The housing 31 is coupled to the bottom surface of the slider upper wall 12A and is disposed between the pair of slider inner side walls 12B. Thus, the slide lock device 30 can be disposed in the slider 12 in a space-saving manner. The pair of slider inner side walls 12B are formed with slider openings 12F at portions opposed to the housing 31.

The respective locking members 32 are arranged in parallel with each other. Each lock member 32 has a shaft portion 32A extending in the front-rear direction. That is, the rotation axis of each locking member 32 extends in the front-rear direction. The front and rear ends of the shaft portion 32A are rotatably supported by the housing 31. Each locking member 32 includes at least one protruding portion 32B protruding from the shaft portion 32A in the radial direction. In the present embodiment, a plurality of convex portions 32B protrude from the shaft portion 32A on one side in the radial direction.

As shown in fig. 6 and 7, the plurality of protrusions 32B preferably extend helically around the rotational axis of the locking member 32. The plurality of convex portions 32B are intermittently formed with each other. The plurality of projections 32B are arranged at regular intervals in the front-rear direction. The housing 31 is preferably provided with a spiral groove 31C for slidably receiving the plurality of projections 32B.

The left and right side portions of the housing 31 are each provided with a housing opening 31D. Each of the lock members 32 pivots between a lock position in which the plurality of projections 32B protrude to the outside of the housing 31 through the housing opening 31D, and a release position in which the plurality of projections 32B are disposed within the housing 31. The plurality of protrusions 32B are arranged above the shaft portion 32A when the lock member 32 is in the release position. When each of the lock members 32 is in the lock position, the pair of arm portions 32C extend laterally in directions toward each other, that is, from the corresponding shaft portion 32A toward the center of the housing 31. The locking position of the locking member 32 is preferably determined by at least one of the plurality of protrusions 32B contacting the housing 31.

Each urging member 33 is provided between the housing 31 and the corresponding locking member 32, and urges the locking member 32 toward the locking position. For example, the urging member 33 is preferably a torsion coil spring. Preferably, the urging member 33 is supported on the shaft portion 32A of the lock member 32.

The operating member 34 includes a fan-shaped main body 34A having surfaces facing left and right, and a pressing portion 34B provided at a lower end of the main body 34A. The operating member 34 is arranged at the center of the housing 31 in the left-right direction. At the rear end of the main body 34A, a support shaft 34C protruding in the left-right direction is provided. The support shaft 34C is disposed at the center of the fan-shaped body 34A when viewed in the left-right direction. In the case where the support shaft 34C is rotatably supported by the housing 31, the operating member 34 is supported by the housing 31 so as to be pivotable about an axis extending laterally. The upper end of the main body 34A protrudes above the housing 31 by passing through an insertion hole 35 formed in the upper housing member 31B. The slide upper wall 12A of the slide 12 is formed with an operation hole 36 penetrating in the up-down direction. The upper end of the main body 34A of the operating member 34 protrudes above the slider 12 by passing through the operating hole 36. The pressing portion 34B is disposed inside the case 31. The left-right width of the pressing portion 34B is formed larger than the left-right width of the operation hole 36. When the locking member 32 is in the locked position, the operating member 34 is in the initial position. At this time, the pressing portion 34B is disposed above the left and right arm portions 32C and is in contact with the arm portion 32C. The operating member 34 may be urged toward the initial position by an urging member 37.

The left and right sliders 12 are pivotably provided with an operation lever 41. The operation lever 41 includes a lever center portion 41A extending in the left-right direction below the front portion of the seat cushion 5 and left and right lever side portions 41B extending rearward from left and right end portions of the lever center portion 41A. Intermediate portions of the left and right lever side portions 41B in the front-rear direction are supported by the corresponding slide members 12 so as to be pivotable about a pivot shaft 41C extending in the left-right direction. The rear ends of the left and right lever sides 41B contact the upper end of the operating member 34 from above. Preferably, the rear ends of the left and right lever side portions 41B are urged upward by urging members not shown in the drawings.

As shown in fig. 9, when the operating member 34 is in the initial position, the left and right locking members 32 are in the locked position. When the left and right locking members 32 are in the locking position, the plurality of protrusions 32B pass through the housing opening 31D and the slider opening 12F and protrude into the corresponding locking holes 15 of the rail 11 to be locked by the locking holes 15. Thereby, the movement of the slider 12 relative to the rail 11 is restricted.

When the user pulls up the lever center portion 41A of the operating lever 41, the rear end of each of the left and right lever side portions 41B pushes down the upper end of the main body 34A. Thereby, as shown in fig. 10, the operating member 34 pivots to move downward, and moves from the initial position to the post-operation position. At this time, the pressing portion 34B of the operating member 34 presses the lock member 32 to move the lock member 32 from the lock position to the release position. Specifically, the pressing portion 34B of the operating member 34 pushes the left and right arm portions 32C downward, whereby the left and right locking members 32 are pivoted from the locking position to the releasing position. Therefore, the plurality of protrusions 32B are separated from the locking holes 15 of the rail 11 and move to the inside of the housing 31. Thereby, the slider 12 becomes movable relative to the rail 11.

The operating member 34 presses the arm portion 32C in a first direction parallel to a tangential direction about the rotational axis of the locking member 32, and when the locking member 32 reaches the release position, each arm portion 32C and the operating member 34 do not overlap in the first direction. In the present embodiment, the first direction is the up-down direction. According to this aspect, even when an excessive load is applied to each of the operation members 34, the load is not transmitted to the arm portion 32C. Thus, breakage of each locking member 32 is prevented.

When each locking member 32 moves from the locking position to the releasing position, at least one protrusion 32B slides in the spiral groove 31C, whereby the locking member 32 can smoothly rotate from the locking position to the releasing position.

In the slide lock device 30, the lock member 32 is rotatably supported by the housing 31, and therefore, when the lock member 32 is pushed by the operation member 34, the lock member 32 can be smoothly moved from the lock position to the release position. Thus, the slide lock device 30 that can be smoothly operated can be provided.

The plurality of protrusions 32B protrude from the housing 31 when the locking member 32 is in the locking position, and the plurality of protrusions 32B are disposed inside the housing 31 when the locking member 32 is in the releasing position, and therefore, the gap between the housing 31 and the rail 11 can be made small.

Since the pair of locking members 32 are arranged parallel to each other and the operating member 34 contacts each of the pair of arm portions 32C, the locking members 32 can be engaged with the rail 11 with good stability.

The above-described assembling method of the sliding apparatus 1 includes a step of assembling the sliding lock apparatus 30 by mounting the lock member 32, the urging member 33, and the operating member 34 to the housing 31, a step of mounting the housing 31 to the slider 12, and a step of mounting the slider 12 to the rail 11. According to this aspect, it is possible to assemble the slide lock device 30 to the inner side of the slide 12 in a work efficient manner. Further, the step of assembling the slide lock device 30 includes a step of mounting the urging member 33 to the lock member 32, a step of causing one of the plurality of housing members to support the lock member 32 and the operating member 34 to which the urging member 33 is mounted, and a step of joining the plurality of housing members to each other. The plurality of housing members includes a lower housing member 31A and an upper housing member 31B.

Second embodiment

Fig. 11 to 15 show a slide lock device 100 according to a second embodiment. The slide lock device 100 according to the second embodiment is different from the slide lock device 30 according to the first embodiment in the configuration of the housing 31, the lock member 32, the operating member 34, the urging member 33, and the like. The configuration of the rail 11 and the slider 12 to which the slide lock device 100 is provided is the same as that in the first embodiment, and therefore, they are denoted by the same reference numerals, and a description thereof will be omitted.

The slide lock device 100 includes a housing 101 coupled to the slider 12, left and right lock members 102 supported by the housing 101 so as to be slidably movable between a release position and a lock position, a pair of front and rear urging members 103 for urging the lock members 102 toward the lock position, and an operating member 104 displaceably supported by the housing 101 and in contact with the lock members 102.

The housing 101 includes a lower housing member 106, an upper housing member 107, and a pair of front and rear guide members 108. The lower housing member 106 and the upper housing member 107 are bonded to each other, and form the outer shell of the hollow housing 101. The left and right side portions of the housing 101 are each formed with a housing opening 109.

The pair of guide members 108 is sandwiched by the lower housing member 106 and the upper housing member 107. Each guide member 108 is formed with a pair of left and right guide holes 108A. Each guide hole 108A penetrates the guide member 108 in the front-rear direction and extends laterally.

The pair of left and right locking members 102 are arranged parallel to each other. Each locking member 102 includes a body 102A extending in the front-rear direction. A plurality of guide shafts 102B are provided at the front end and the rear end of the main body 102A, respectively. Each guide shaft 102B is engaged with one of the respective guide holes 108A formed in the front and rear guide members 108. The left and right locking members 102 are supported by the housing 101 so as to be slidably movable in the left-right direction due to the front and rear guide members 108. Further, a lower portion of each main body 102A is provided with a guide projection 102C protruding downward. The upper surface of the lower housing member 106 is formed with a laterally extending guide groove 106A. The left and right guide bosses 102C are engaged with the guide grooves 106A.

Each locking member 102 includes a plurality of protrusions 102D protruding laterally outward from the body 102A. The inner side surface of each main body 102A is formed with a pair of front and rear receiving holes 102E. Each urging member 103 is a compression coil spring extending laterally. The left and right ends of the pressing member 103 on the front side are received in the left and right receiving holes 102E provided on the front side. The left and right ends of the pressing member 103 on the rear side are received in the left and right receiving holes 102E provided on the rear side. The urging member 103 urges the locking member 102 in a direction away from each other.

Each of the lock members 102 slidably moves between a lock position in which the plurality of projections 102D protrude to the outside of the housing 101 through the housing opening 31D, and a release position in which the plurality of projections 102D are disposed within the housing 101. The locking and releasing positions of each locking member 102 are defined by guide members 108. When the locking member 102 is in the locked position, the sliding lock apparatus 100 is in the locked state, and when the locking member 102 is in the released position, the sliding lock apparatus 100 is in the released state. Each locking member 102 is urged towards the locking position by an urging member 103.

The operation member 104 includes an operation shaft 104A extending in the up-down direction, a connection shaft 104B extending in the front-rear direction from a lower portion of the operation shaft 104A, and a pair of front and rear cam members 104C coupled to front and rear ends of the connection shaft 104B. The upper end of the operation shaft 104A protrudes above the housing 101 by passing through an operation hole 107A formed in the upper portion of the upper housing member 107. The operation member 104 is supported by the housing 101 so as to be slidably movable in the up-down direction. The front and rear cam members 104C are arranged between the front and rear urging members 103.

Each cam member 104C includes a central portion 104D coupled to the connecting shaft 104B, left and right cam arm portions 104E extending laterally outward and downward from an upper end of the central portion 104D, and a stopper portion 104F extending laterally outward from a lower end of the central portion 104D. The distal end portion of each cam arm portion 104E is provided with a laterally inward and downward facing cam surface 104G. An upper portion of the body 102A of each of the left and right locking members 102 is provided with a pair of front and rear cam surfaces 102F facing laterally outward and upward. The pair of front and rear cam surfaces 104G are opposite the corresponding pair of cam surfaces 102F.

The operating member 104 is movable between an initial position and a post-operation position that is located below the initial position. Between the lower end of the operation shaft 104A and the housing 101, a pressing member (not shown in the drawings) is provided. With the urging member, the operation member 104 is urged toward the initial position.

When the operating member 104 is in the initial position, the cam surface 104G is spaced upwardly from the cam surface 102F. At this time, each stopper 104F of the operating member 104 pushes the inner side surface of the main body 102A of the corresponding locking member 102 laterally outward, and each locking member 102 is held in the locking position. The left and right sides of each stop 104F are preferably angled upward and laterally inward. When the left and right locking members 102 are in the locking position, the plurality of protrusions 102D protrude into the corresponding locking holes 15 of the rail 11 by passing through the housing opening 109 and the slider opening 12F, and are locked to the locking holes 15. Thereby, the movement of the slider 12 relative to the rail 11 is restricted.

An upper end of the operation shaft 104A is in contact with a rear end of one of the respective lever side portions 41B of the operation lever 41. When the user pulls up the lever center portion 41A of the operation lever 41, the rear end of each of the left and right lever side portions 41B pushes down the upper end of the operation shaft 104A. Thus, the operating member 104 slidingly moves downward and moves from the initial position to the post-operation position. At this time, each stopper 104F of the operating member 104 is separated from the respective main body 102A, and each locking member 102 becomes movable from the locking position to the releasing position.

As the operating member 104 moves further downward toward the post-operation position, each cam surface 104G pushes the corresponding cam surface 102F downward and laterally inward. Thereby, the left and right locking members 102 are moved from the locking position to the releasing position. Accordingly, the plurality of protrusions 102D are separated from the locking holes 15 of the rail 11 and move to the inside of the housing 101. Thereby, the slider 12 becomes movable relative to the rail 11.

The angle of each cam surface 104G and the angle of each cam surface 102F with respect to the water surface (surface perpendicular to the axis of the operation shaft 104A) are preferably greater than or equal to 16 degrees and less than or equal to 27 degrees, more preferably greater than or equal to 20 degrees and less than or equal to 25 degrees. Thereby, a large stroke of the operation member 104 can be realized. Thus, a large stroke of each locking member 102 can be achieved, and a large protruding length of each boss 102D into the locking hole 15 can be achieved. Further, a large distance between each of the convex portions 102D and the locking hole 15 when the locking member 102 is in the release position can be achieved.

Third embodiment

As shown in fig. 16 to 18, the slide lock device 130 according to the third embodiment is different from the slide lock device 100 according to the second embodiment in the configuration of the lock member 102 and the operation member 104. In the slide lock device 130, the same configuration as that of the slide lock device 100 is denoted by the same reference numeral, and a description thereof will be omitted.

In the slide lock device 130, left and right lock members 131 are supported by the housing 101 so as to be slidably movable in the left-right direction. Further, the operating member 132 is supported by the housing 101 so as to be slidably movable in the up-down direction.

Each of the locking members 131 includes a main body 131A extending in the front-rear direction and a connecting portion 131B extending from a front end or a rear end of the main body 131A in the left-right direction toward the center of the housing 101. A plurality of protrusions 131C are provided on a side surface of the main body 131A. The configuration of the body 131A and the convex portion 131C may be the same as the configuration of the body 102A and the convex portion 102D.

Preferably, in one locking member 131, the connection portion 131B is provided at the front end of the main body 131A, and in the other locking member 131, the connection portion 131B is provided at the rear end of the main body 131A. Each of the connection portions 131B is formed with a cam groove 131D. As shown in fig. 17 and 18, the cam groove 131D extends upward from the side of the main body 131A toward the protruding end of the connecting portion 131B. In the present embodiment, the cam groove 131D extends straight. The cam groove 131D penetrates the connection portion 131B in the front-rear direction.

The left and right locking members 131 are movable between a locking position in which the plurality of projections 131C project laterally outward from the housing 101, and a releasing position in which the plurality of projections 131C are retracted into the housing 101.

The operating member 132 includes an operating shaft 132A extending in the up-down direction and a connecting shaft 132B extending forward and backward from the lower end of the operating shaft 132A. The upper end of the operation shaft 132A protrudes upward from the housing 101. The connection shaft 132B is disposed inside the housing 101. The operating member 132 is supported by the housing 101 so as to be movable in the up-down direction.

The front end of the connecting shaft 132B is engaged with the cam groove 131D of one of the left and right locking members 131.

The slide lock device 130 includes urging members 134 for urging the left and right lock members 131 toward the lock position. For example, the urging member 134 may be a compression coil spring. For example, the pressing member 134 may be disposed between the left and right bodies 131A. The urging member 134 may urge the left and right locking members 131 toward the locking position via the operating member 132.

A state in which the left and right locking members 131 are in the locking position is referred to as a locking state of the slide locking device 130. A state in which the left and right locking members 131 are in the release position is referred to as a release state of the slide locking device 130. When the slide locking device 130 is in the locked state, the left and right plurality of protrusions 131C protrude laterally outward from the housing 101 and are locked in the plurality of locking holes 15 of the rail 11. Thereby, the movement of the slider 12 relative to the rail 11 is restricted. When the slide locking device 130 is in the released state, the left and right plurality of protrusions 131C are retracted into the housing 101 and separated from the plurality of locking holes 15 of the rail 11. Thereby allowing movement of the slider 12 relative to the track 11.

When the user operates the operation lever 41, the rear end of each lever side portion 41B of the operation lever 41 pushes down the upper end of the operation shaft 132A, and the operation member 132 moves downward. Accordingly, the front and rear ends of the connection shaft 132B push down the corresponding cam grooves 131D, so that the left and right locking members 131 move to the release positions.

In the slide lock device 130 according to the third embodiment, the guide member 108 and the cam member 104C can be omitted, and thus the number of components can be reduced, as compared with the slide lock device 100 according to the second embodiment. In addition, as in the slide lock device 100 according to the second embodiment, in the slide lock device 130 according to the third embodiment, a large stroke of the lock member 131 can be achieved.

Fourth embodiment

As shown in fig. 19, the slide lock device 150 according to the fourth embodiment is different from the slide lock device 130 according to the third embodiment in the shape of the cam groove 131D. Each cam groove 131D extends in an arc shape from the side of the main body 131A toward the protruding end of the connecting portion 131B. Each cam groove 131D is formed in an arc shape protruding forward and laterally outward. Therefore, the operation member 132 requires a relatively large operation force when starting to move from the initial state toward the post-operation position, and the required operation force becomes smaller as it approaches the post-operation position.

Fifth embodiment

As shown in fig. 20, the slide lock device 160 according to the fifth embodiment is different from the slide lock device 130 according to the third embodiment in the connection portion 131B of each lock member 131 and the operating member 132. The front and rear connection parts 131B are each formed with a cam groove 131D penetrating in the up-down direction. Each cam groove 131D extends rearward from the main body 131A side toward the protruding end of the connecting portion 131B when viewed from above.

The operation member 161 includes: an operation shaft 161A provided in the housing 101 so as to be movable in the up-down direction; a transmission member 162 extending in the front-rear direction and provided in the housing 101 so as to be movable in the front-rear direction; and a plurality of pins 163 provided at front and rear ends of the transmission member 162.

The transmission member 162 is provided with a cam surface 162A slidably contacting the lower end of the operating shaft 161A. The cam surface 162A is preferably inclined downward toward the rear. When the operating shaft 161A moves downward, the lower end of the operating shaft 161A pushes the cam surface 162A, and the transmission member 162 moves forward. At this time, each pin 163 pushes the corresponding cam groove 131D, whereby the lock member 131 moves from the lock position to the release position.

Sixth embodiment

As shown in fig. 21, the slide lock device 170 according to the sixth embodiment is different from the slide lock device 130 according to the third embodiment in the lock member 131 and the operating member 132. Each of the locking members 131 includes a first rack 171 extending in the left-right direction. The operating member 132 includes an operating shaft 132A extending in the up-down direction, left and right second racks 172 provided on left and right side surfaces of the operating shaft 132A and extending in the up-down direction, and left and right pinions 173 rotatably supported by the housing 101. The left pinion 173 is engaged with the left first rack 171 and the left second rack 172. The right pinion 173 is engaged with the right first rack 171 and the right second rack 172.

When the operation shaft 132A is in the initial position, the left and right locking members 131 are in the locking position. When the operation shaft 132A moves from the initial position to the post-operation position, the left and right pinions 173 that are engaged with the left and right second racks 172 rotate. Thereby, the left and right locking members 131 having the first racks 171 engaged with the respective pinions 173 are moved from the locking position to the releasing position.

The screw shaft 183 extends laterally, and each of left and right ends thereof is formed with an external thread 183A. The left and right external threads 183A have different rotational directions (spiral directions). The mutually opposing surfaces of the main body 131A of the left and right locking members 131 are each formed with an internally threaded hole 184 extending in the left-right direction. Left and right external threads 183A of screw shaft 183 are threadedly engaged with transversely corresponding internally threaded holes 184. At the central portion of the screw shaft 183, a pinion gear 183B that engages with the rack 182A is provided.

An upper end of the operation shaft 182 contacts a rear end of one of the respective lever side portions 41B of the operation lever 41. When the user operates the operation lever 41, the operation shaft 182 is pushed downward by the operation lever 41, and the operation shaft 182 moves downward. Thus, the pinion gear 183B engaged with the rack 182A rotates, and the screw shaft 183 rotates. As a result, the left and right external threads 183A are threadedly advanced with respect to the corresponding internal threaded holes 184, whereby the left and right locking members 131 are moved in directions toward each other. That is, the left and right locking members 131 are moved from the locking position to the releasing position. When the user stops the operation of the operation lever 41, the left and right locking members 131 move from the release position to the locking position due to the urging force of the urging member 134, and the operation shaft 182 moves to the initial position.

The operating member 132 includes an operating shaft 132A extending in the up-down direction, left and right arms 192 and left and right stoppers 193 provided on the operating shaft 132A. The operating member 132 is preferably disposed in front of and behind the support shaft 191. The operation shaft 132A is supported by the housing 101 so as to be displaceable in the up-down direction. The upper end of the operation shaft 132A protrudes above the housing 101. Left and right stoppers 193 protrude leftward and rightward from the lower end of the operation shaft 132A. Left and right arms 192 are disposed in the housing 101 and protrude leftward and rightward from an upper portion of the operation shaft 132A. Between the lower end of the operation shaft 132A and the housing 101, a pressing member 195 for pressing the operation shaft 132A upward (toward the initial position) is provided.

When the operating member 132 is in the initial position, the left and right stoppers 193 contact the inner side surfaces of the main body 131A of the left and right locking members 131 and hold the left and right locking members 131 in the locking position. When the user operates the operation lever 41, the operation shaft 132A is pushed downward by the operation lever 41, and the operation shaft 132A moves downward. Accordingly, the left and right stoppers 193 are separated from the corresponding bodies 131A, so that the left and right locking members 131 become movable to the release positions. In this state, when the operating member 132 is further moved downward, the left and right arms 192 push the corresponding connection portions 131B downward. Thereby, the left and right locking members 131 pivot about the supporting shaft 191 and move from the locking position to the releasing position. Thereby, the left and right locking members 131 are separated from the locking holes 15 of the rail 11, so that the slider 12 becomes movable with respect to the rail 11. When the user stops the operation of the operation lever 41, the left and right locking members 131 return to the locking position due to the urging force of the urging member 134, and the operation member 132 returns to the initial position due to the urging force of the urging member 195.

The operation shaft 132A of the operation member 132 is connected to the left and right locking members 131 through left and right links 201. Each link 201 includes a first shaft 201A pivotably coupled to the operating shaft 132A and a second shaft 201B pivotably coupled to the locking member 131. The first shaft 201A and the second shaft 201B extend parallel to each other in the front-rear direction.

At least one of the front end and the rear end of the body 131A of the locking member 131 is provided with a guide pin 203 protruding in the front-rear direction. The housing 101 is formed with left and right guide slots 204 for slidably receiving the left and right guide pins 203. Each guide slot 204 is inclined downward toward the laterally inner side.

When the user operates the operation lever 41, the operation shaft 132A is pushed downward by the operation lever 41, and the operation shaft 132A moves downward. Accordingly, the left and right locking members 131 connected to the operation shaft 132A via the link 201 are moved from the locking position to the releasing position. That is, the left and right locking members 131 are pulled by the operation shaft 132A to move laterally inward from the housing 101. At this time, since the left and right guide pins 203 are guided by the left and right guide slots 204, tilting of the left and right locking members 131 is suppressed.

Each of the front and rear ends of the main body 131A of each of the left and right locking members 131 is provided with a first guide pin 223 protruding in the front-rear direction. The front and rear first guide pins 223 are received in the corresponding guide slots 221D. Thereby, the left and right locking members 131 are supported by the housing 101 so as to be slidably movable left and right between the locking position and the releasing position. At the lower end of each body 131A, a guide arm 224 extending downward is provided. The lower end portion of each guide arm 224 is provided with a lock portion 224A bent laterally outward.

The operating member 132 includes an operating shaft 226, a cam plate 227, and a pressing member 228. The operation shaft 226 extends in the up-down direction. The operation shaft 226 is formed in a polygonal pillar shape. In the present embodiment, the operation shaft 226 has a quadrangular cross section. The operation shaft 226 includes a torsion portion 226A in an intermediate portion in the up-down direction. At the torsion portion 226A, the operation shaft 226 is twisted by 90 degrees about an axis extending in the up-down direction. The operation shaft 226 includes a stopper 226B protruding sideways from a portion above the torsion portion 226A.

An upper portion of the operation shaft 226 is inserted into the polygonal hole 221E so as to be movable in the up-down direction. The operation shaft 226 engages with the polygonal hole 221E, thereby restricting rotation about an axis extending in the up-down direction. The stopper 226B is disposed below the upper wall 221A. The stopper 226B determines the initial position of the operation shaft 226 by contacting the upper wall 221A. An upper end of the operation shaft 226 is in contact with a rear end of one of the respective lever side portions 41B of the operation lever 41.

The cam plate 227 is a plate-like member having upwardly and downwardly facing surfaces. The cam plate 227 is preferably formed in a circular shape. At the center of the cam plate 227, an insertion hole 227A penetrating in the up-down direction is formed. A pair of cam slots 227B are formed around the insertion hole 227A of the cam plate 227. The pair of cam slots 227B are formed to be rotationally symmetrical about the axis of the cam plate 227. Each cam slot 227B penetrates the cam plate 227 in the up-down direction. The cam slot 227B extends in the circumferential direction of the cam plate 227 and has a first end 227C and a second end 227D. The distance between the first end 227C and the center of the cam plate 227 is greater than the distance between the second end 227D and the center of the cam plate 227.

The lower portion of the operation shaft 226 is inserted into the insertion hole 227A so as to be movable in the up-down direction. The insertion hole 227A is engaged with a lower portion of the operation shaft 226 so as to be non-rotatable with respect to the operation shaft 226.

The urging member 228 is disposed between the stopper 226B and the cam plate 227. The urging member 228 may be a compression coil spring. The urging member 228 urges the operation shaft 226 upward with respect to the cam plate 227. That is, the urging member 228 urges the operation shaft 226 toward the initial position.

When the operation shaft 226 is at the initial position, a lower portion of the operation shaft 226 is seated in the insertion hole 227A. At this time, each of the left and right guide arms 224 is seated in the first end 227C of the corresponding cam slot 227B. Thus, the left and right locking members 131 are in their locking positions distant from each other in the left-right direction.

When the user operates the operation lever 41, the operation shaft 226 is pushed downward by the operation lever 41, and the operation shaft 226 moves downward. Thus, the operation shaft 132A moves downward with respect to the cam plate 227, and the torsion portion 226A enters the insertion hole 227A. Thus, the cam plate 227 rotates and each of the left and right guide arms 224 moves in the corresponding cam slot 227B from the first end 227C to the second end 227D. Thereby, the left and right locking members 131 move in the left-right direction in the direction toward each other. That is, the left and right locking members 131 are moved from the locking position to the releasing position.

At this time, the left and right locking members 131 are guided by the inclined surfaces 292 and move laterally inward. That is, the left and right locking members 131 are moved to the release position.

Fifteenth embodiment

As shown in fig. 36 to 40, the slide lock device 300 according to the fifteenth embodiment is different from the slide lock device 100 according to the second embodiment in the configuration of the lock member 102, the operation member 104, the guide member 108, and the like. The same configurations are denoted by the same reference numerals, and description thereof will be omitted.

As shown in fig. 36, the housing 101 is configured to be fastened to the lower surface of the slider upper wall 12A by a bracket 301. The bracket 301 extends in the front-rear direction and is fastened to the slider upper wall 12A at the front end and the rear end. The central portion 301A of the holder 301 in the front-rear direction is recessed downward. The housing 101 is fixed to the upper surface of the central portion.

The operation member 104 includes an operation shaft 104A and a connection member 303 extending forward and backward from a lower end of the operation shaft 104A. At each of the front end and the rear end of the connection member 303, a pressing shaft 304 extending in the front-rear direction is provided. A pair of front and rear stoppers 305 are provided on the lower sides of the front and rear portions of the connection member 303. Each stopper 305 extends downward from the connection member 303 and extends to both the left and right sides. The operating member 104 is urged upwardly, i.e. towards the initial position, by the urging member 306.

The front and rear guide members 108 are formed with second guide holes 307 for receiving the front and rear pressing shafts 304. Each of the second guide holes 307 extends in the up-down direction. Each pressing shaft 304 is movable in the up-down direction in the corresponding second guide hole 307.

Between the front end of the connection member 303 and the front guide member 108, left and right cam members 310 are provided. Also between the rear end of the connection member 303 and the rear guide member 108, similar left and right cam members 310 are provided. When the pressing shaft 304 moves downward, the left cam member 310 moves the left locking member 102 rightward, i.e., toward the release position. When the pressing shaft 304 moves downward, the right cam member 310 moves the right locking member 102 leftward, i.e., toward the release position. The left and right cam members 310 are supported by the housing 101 so as to be slidably movable in the left-right direction.

The left cam member 310 includes a cam surface 310A disposed below the pressing shaft 304 and a locking portion 310B for locking the guide shaft 102B of the left locking member 102. Cam surface 310A slopes downward toward the left. The locking portion 310B may be a hook locking the guide shaft 102B or a hole into which the guide shaft 102B protrudes. The right cam member 310 is formed to be bilaterally symmetrical with the left cam member 310. The left and right cam members 310 have an overlap when viewed from the front. The left and right cam surfaces 310A intersect each other when viewed from the front.

As shown in fig. 39, when the operation member 104 is in the initial position, the pressing shaft 304 is separated upward from the cam surface 310A of each cam member 310. At this time, the left and right locking members 102 are disposed in the locking position due to the urging member 103. Further, each stopper 305 of the operation member 104 contacts the inner side surface of the main body 102A of the corresponding locking member 102, and each locking member 102 is held in the locking position.

When the user pulls up the lever center portion 41A of the operation lever 41, the rear end of each of the left and right lever side portions 41B pushes the upper end of the operation shaft 104A. Thereby, as shown in fig. 40, the operation member 104 is slidingly moved downward, and is moved from the initial position to the post-operation position. At this time, each stopper 305 of the operation member 104 is separated from each main body 102A, and each locking member 102 becomes movable from the locking position to the releasing position.

As the operating member 104 moves further downward toward the post-operation position, each pressing shaft 304 pushes the corresponding cam surface 310A downward. Thus, the left and right cam members 310 move laterally inward and the locking member 102 moves from the locking position to the release position. Accordingly, the plurality of protrusions 102D are separated from the locking holes 15 of the rail 11 and move to the inside of the housing 101. Thereby, the slider 12 becomes movable relative to the rail 11.

When the locking member 102 reaches the release position, the pressing shaft 304 is separated from the end of the cam surface 310A. Thus, the locking member 102 is prevented from receiving a load after reaching the release position. Further, each cam member 310 is provided with a concave portion 310C recessed downward in the vicinity of the cam surface 310A. Due to the concave portion 310C, even if the pressing shaft 304 moves further downward, contact between the pressing shaft 304 and the cam member 310 in the up-down direction can be avoided.

The second screw member 407 has a second gear 407C engaged with the driving gear 413A. Each of the driving gear 413A, the first gear 406C, and the second gear 407C may be spur gears. When the driving shaft 413 is rotated, the first screw member 406 and the second screw member 407 are rotated in the same direction as each other. The first gear 406C and the second gear 407C may be symmetrical in shape.

The first gear 406C is supported so as to be displaceable in the front-rear direction (axial direction) with respect to the shaft portion 406A of the first screw member 406 and is non-rotatable with respect to the shaft portion 406A. For example, it is preferable that a polygonal hole is formed at the center of the first gear 406C, and the shaft portion 406A has a polygonal columnar portion fitted in the polygonal hole so as to be non-rotatable and movable in the front-rear direction. Similarly, the second gear 407C is supported so as to be displaceable in the front-rear direction (axial direction) with respect to the shaft portion 407A of the second screw member 407, and is non-rotatable with respect to the shaft portion 407A. The first gear 406C and the second gear 407C have lengths in the front-rear direction. Therefore, even when the first gear 406C moves in the front-rear direction, engagement between the first gear 406C and the driving gear 413A is maintained. Similarly, even when the second gear 407C moves in the front-rear direction, engagement between the second gear 407C and the driving gear 413A is maintained.

The screw assembly 403 includes a first urging member 406D for urging the first screw member 406 in the front-rear direction.

In the present embodiment, the second urging member 407D is supported on the front end of the shaft portion 407A. The second urging member 407D is disposed between the screw 406B and the front bearing 415. The second urging member 407D urges the shaft portion 407A and the screw 407B rearward with respect to the gear housing 411. The first urging member 406D and the second urging member 407D may be at least one coil spring, compression coil spring, leaf spring, rubber, or the like.

The first buffer member 406E may be disposed in a gap between the first screw member 406 and the gear housing 411 in the front-rear direction. The first cushioning member 406E is preferably disposed on an end of the shaft portion 406A opposite the first urging member 406D. In the present embodiment, the first cushioning member 406E is supported on the front end of the shaft portion 406A. The first cushioning member 406E is disposed between the threads 406B and the front bearing 415.

The second buffer member 407E may be disposed in a gap between the second screw member 407 and the gear housing 411 in the front-rear direction. The second cushioning member 407E is preferably disposed on an end of the shaft portion 407A opposite the second urging member 407D. In the present embodiment, the second buffer member 407E is supported on the rear end of the shaft portion 407A. The second cushioning member 407E is disposed between the threads 407B and the rear bearing 415. The first cushioning member 406E and the second cushioning member 407E may be rubber, nonwoven fabric, or the like.

As shown in fig. 41 and 42, the gear housing 411 has a housing opening 418, which is an opening for exposing the first screw member 406 and the second screw member 407 to the side. The threads 406B of the first threaded member 406 pass through a housing opening 418 formed in the left side portion of the gear housing 411 and protrude leftward. Similarly, the screw 407B of the second screw member 407 passes through a housing opening 418 formed in the right side portion of the gear housing 411 and protrudes rightward. A housing opening 418 is formed in the housing body 411A.

The first bracket 412 extends in the front-rear direction, and includes a first coupling portion 412A provided at a front end and a second coupling portion 412B provided at a rear end. The first bracket 412 is coupled to the lower surface of the slider upper wall 12A of the slider 12 at a first coupling portion 412A and a second coupling portion 412B. The first bracket 412 includes a support portion 412C extending from the first coupling portion 412A to the second coupling portion 412B. The first bracket 412 is preferably an integral metal member including a first coupling portion 412A, a second coupling portion 412B, and a supporting portion 412C. The support portion 412C has a portion disposed under the first and second coupling portions 412A and 412B. Due to the support portion 412C, the first bracket 412 cooperates with the slider upper wall 12A to form a closed structure. The gear housing 411 is disposed between the slider upper wall 12A of the slider 12 and the support portion 412C. The first bracket 412 is formed by bending a metal sheet. The first coupling portion 412A extends forward from the front of the gear housing 411, and the second coupling portion 412B extends rearward from the rear of the gear housing 411. The first and second coupling portions 412A and 412B are preferably fastened to the slider upper wall 12A by fastening members such as threads, rivets, or the like. The distance between the fastening points of the first coupling portion 412A and the second coupling portion 412B is set to be longer than the front-rear length of the gear housing 411.

Behind the first bracket 412, a second bracket 421 for supporting the electric motor 404 on the slider upper wall 12A of the slider 12 is provided. The second bracket 421 includes a coupling portion 421A coupled to the slider upper wall 12A and a supporting portion 421B extending downward from the coupling portion 421A in a direction opposite to the slider upper wall 12A. The supporting portion 421B is perpendicular to the coupling portion 421A, so that the second bracket 421 is formed in an L shape. The electric motor 404 is coupled to the supporting portion 421B at one end portion thereof. In the present embodiment, the electric motor 404 is disposed below the joint 421A, and the second bracket 421 supports the end of the electric motor 404 on the side of the screw members 406, 407 in a cantilever manner.

The rear end of the driving shaft 413 protrudes rearward from the rear support member 411C of the gear housing 411 and extends rearward to pass through a through hole formed in the first bracket 412. The rotation shaft of the electric motor 404 is connected to the rear end portion of the drive shaft 413. The rotation shaft of the electric motor 404 and the drive shaft 413 are preferably coupled to each other by coupling. Further, the rotation shaft of the electric motor 404 and the driving shaft 413 may have fitting portions engaged with each other. The rotation shaft of the electric motor 404 and the drive shaft 413 are arranged on the same straight line. The electric motor 404 is formed in a cylindrical shape and extends in the front-rear direction.

A decelerator may be provided between the rotation shaft of the electric motor 404 and the driving shaft 413. For example, the decelerator is preferably a planetary gear mechanism. The decelerator is preferably provided on a surface of the support portion 421B of the second bracket 421 opposite to the electric motor 404. In another embodiment, the decelerator may be supported on the rear end surface of the gear housing 411. The decelerator is an optional construction and may be omitted.

The rotation shaft of the electric motor 404 and the drive shaft 413 may be coupled via a flexible shaft. Thereby, the rotation shaft of the electric motor 404 and the drive shaft 413 can be arranged to be offset from each other. In this way, the degree of freedom in layout of the screw assembly 403 and the electric motor 404 is improved.

The screw assembly 403, the electric motor 404, the first bracket 412 and the second bracket 421 are disposed below the slider upper wall 12A and between the left and right slider inner side walls 12B. The left and right slider inner side walls 12B each have a slider opening 12F at a position corresponding to the screw assembly 403. The slider opening 12F is formed in a recess 12E of the slider inner side wall 12B. The left portion of the thread 406B of the first screw member 406 passes through the left housing opening 418 of the gear housing 411 and the slider opening 12F of the left slider inner side wall 12B, and protrudes leftward from the left slider inner side wall 12B. Similarly, the right portion of the screw 407B of the second screw member 07 passes through the right housing opening 418 of the gear housing 411 and the slider opening 12F of the right slider inner side wall 12B, and protrudes rightward from the right slider inner side wall 12B.

The rail 11 is formed with a plurality of locking holes 15 extending in the front-rear direction to engage with the screw members 406, 407. The first screw member 406 is engaged with the plurality of locking holes 15 at the left portion of the screw 406B, and moves forward and backward with respect to the locking holes 15 by rotating. Similarly, the second screw member 407 is engaged with the plurality of locking holes 15 at the right portion of the screw 407B, and moves forward or backward with respect to the locking holes 15 by rotating.

The rotation of the electric motor 404 is transmitted to the first screw member 406 and the second screw member 407 via the rotation shaft, the drive shaft 413, the drive gear 413A, and the first gear 406C or the second gear 407C. As a result, the first screw member 406 and the second screw member 407 rotate in the same direction. When the first screw member 406 and the second screw member 407 are rotated, the first screw member 406 and the second screw member 407 are moved forward or backward with respect to the locking hole 15, and the slider 12 is moved forward or backward with respect to the rail 11.

In the electric slide rail 401 according to the present embodiment, since the electric motor 404 and the screw assembly 403 are fixed to the slider 12, tilting of the first screw member 406 and the second screw member 407 with respect to the locking hole 15 is suppressed. Accordingly, the first screw member 406 can be engaged with the locking hole 15 at an appropriate angle, and the rotation of the first screw member 406 becomes smooth. The same applies to the second screw member 407. As a result, the electric slide rail 401 that can be smoothly operated can be provided. Further, since the electric motor 404 is mounted to the slider 12 received in the rail 11, the external shape of the electric slide rail 401 can be made compact. Further, since the electric motor 404 is disposed inside the slider 12, the distance between the electric motor 404 and the screw assembly 403 can be reduced, and the length of the drive shaft 413 connecting the electric motor 404 and the screw assembly 403 can be shortened. Therefore, deflection of the drive shaft 413 is suppressed, and the screw assembly 403 can smoothly rotate.

Since the screw assembly 403 includes two screw members, i.e., the first screw member 406 and the second screw member 407, the screw assembly 403 can be made compact while being engaged with the locking holes 15 of the two rail inner side walls. Further, since the direction of the reaction force received by the first screw member 406 from the locking hole 15 and the direction of the reaction force received by the second screw member 407 from the locking hole 15 are opposite to each other, the first screw member 406 is reliably engaged with the locking hole 15, and the second screw member 407 is reliably engaged with the locking hole 15.

The first screw member 406 and the second screw member 407 constitute the screw assembly 403 together with the gear housing 411 and the first bracket 412, and thus, assembly to the slider 12 is easy.

Since the first urging member 406D urges the screw 406B forward, the screw 406B can contact the front edge of the locking hole 15 when the electric motor 404 is stopped. Further, since the second pressing member 407D presses the screw 407B rearward, the screw 407B can contact the rear edge of the locking hole 15 when the electric motor 404 is stopped. Due to this, rattling of the screw assembly 403 with respect to the rail 11 can be suppressed.

Due to the first cushioning member 406E, the collision between the first screw member 406 and the bearing 415 in the front-rear direction is suppressed, and the generation of collision sound is suppressed. Due to the second buffer member 407E, the collision between the second screw member 407 and the bearing 415 in the front-rear direction is suppressed, and the generation of collision sound is suppressed.

Seventeenth embodiment

Referring to fig. 44 and 45, an electric slide rail 450 according to a seventeenth embodiment will be described. As shown in fig. 44, in the electric slide rail 450, the first lock plate 451 is provided between the screw 406B of the first screw member 406 and the first gear 406C. The first locking plate 451 includes a plate portion 451A having forward and rearward facing surfaces and fixed to the gear housing 411, an insertion hole 451B penetrating the plate portion 451A in the forward and rearward direction, and at least one protruding portion 451C protruding from the plate portion 451A toward the screw thread 406B. The shaft portion 406A of the first screw member 406 passes through the insertion hole 451B.

At the rear end of the thread 406B, at least one boss 454 is provided that protrudes rearward. The first urging member 406D is provided between the plate portion 451A of the first lock plate 451 and the screw thread 406B. The first urging member 406D urges the screw 406B forward with respect to the first lock plate 451.

As shown in fig. 45, the second locking plate 461 is provided between the screw 407B of the second screw member 407 and the front bearing 415. The second locking plate 461 includes a plate portion 461A having forward and rearward facing surfaces and fixed to the gear housing 411, an insertion hole 461B penetrating the plate portion 461A in the front-rear direction, and at least one protruding portion 461C protruding from the plate portion 461A toward the screw 407B. The shaft portion 407A of the second screw member 407 passes through the insertion hole 461B.

At the front end of the screw 407B, at least one convex portion 464 protruding forward is provided. The second urging member 407D is disposed between the plate portion 461A of the second lock plate 461 and the screw 407B. The second urging member 407D urges the screw 407B rearward with respect to the second lock plate 461.

When a predetermined forward load is not applied to the slider 12, the protruding portion 451C of the first lock plate 451 and the protruding portion 454 of the screw 406B are separated from each other in the front-rear direction due to the urging force of the first urging member 406D. Accordingly, the first screw member 406 can rotate with respect to the first locking plate 451 and the gear housing 411. Similarly, when a predetermined rearward load is not applied to the slider 12, the convex portion 461C of the second lock plate 461 and the convex portion 464 of the screw 407B are separated from each other in the front-rear direction due to the urging force of the second urging member 407D. Accordingly, the second screw member 407 can rotate with respect to the second locking plate 461 and the gear housing 411. Note that when the electric motor 404 is also rotating, the first screw member 406 and the second screw member 407 can similarly rotate with respect to the gear housing 411.

When a predetermined forward load is applied to the slider 12, the gear housing 411 and the first lock plate 451 move forward against the urging force of the first urging member 406D, and the projection 451C of the first lock plate 451 and the projection 454 of the screw 406B are engaged in the circumferential direction. Thereby, the first screw member 406 becomes non-rotatable with respect to the first locking plate 451 and the gear housing 411. Similarly, when a predetermined rearward load is applied to the slider 12, the gear housing 411 and the second lock plate 461 move rearward against the urging force of the second urging member 407D, and the convex portion 461C of the second lock plate 461 and the convex portion 464 of the screw 407B are engaged in the circumferential direction. Thereby, the second screw member 407 becomes non-rotatable with respect to the second locking plate 461 and the gear housing 411. In this way, when a predetermined forward or backward load is applied to the slider 12, the rotation of the first screw member 406 or the second screw member 407 is restricted, whereby the movement of the slider 12 with respect to the rail 11 is restricted.

Eighteenth embodiment

Referring to fig. 46, an electric slide rail 470 according to an eighteenth embodiment will be described. As shown in fig. 46, the first screw member 406 may be longitudinally divided into a front part 471 and a rear part 472. The front part 471 and the rear part 472 are connected to be movable relative to each other in the front-rear direction and not rotatable relative to each other. For example, the rear end of the front part 471 is preferably formed with a polygonal hole 471A, and the front end of the rear part 472 is preferably provided with a polygonal column 472A protruding into the polygonal hole 471A to be movable in the front-rear direction and non-rotatable.

The front 471 is urged rearward relative to the gear housing 411 by a front urging member 474. The rear portion 472 is urged forward relative to the gear housing 411 by a rear urging member 475. Thus, the threads 406B of the front portion 471 are in contact with the rear edge of the locking hole 15 of the rail 11, and the threads 406B of the rear portion 472 are in contact with the front edge of the locking hole 15 of the rail 11. Thus, rattling of the rail 11 with respect to the screw member 403 is suppressed. The same applies to the second screw member 407.

The axial length of the first screw member 406 including the front portion 471 and the rear portion 472 is preferably set to be shorter than the axial length of the electric motor 404. The axial length of the first screw member 406 including the front portion 471 and the rear portion 472 may be set to be longer than the axial length of the electric motor 404. The same applies to the second screw member 407.

As shown in fig. 47, the rearmost locking hole 15 of the rail 11 preferably has an extension 477 that expands in width forward. In a state before the slider 12 having the screw assembly 403 mounted thereto is assembled with the rail 11, the front part 471 and the rear part 472 are brought into a position closest to each other by the front pressing member 474 and the rear pressing member 475. Thus, the distance between the rear end of the thread 406B of the front portion 471 and the front end of the thread 406B of the rear portion 472, i.e., the pitch, is short. Therefore, if the plurality of locking holes 15 are arranged at equal intervals, when the slider 12 is inserted into the rail 11 from the rear, the front end of the thread 406B of the rear portion 472 cannot be smoothly inserted into the rearmost locking hole 15. In the present embodiment, since the rearmost locking hole 15 has the extension 477, the front end of the thread 406B of the rear portion 472 can be smoothly inserted into the rearmost locking hole 15. After the front end of the screw 406B of the rear portion 472 is inserted into the rearmost locking hole 15, the rear portion 472 relatively moves rearward away from the front portion 471 against the urging force of the rear urging member 475 according to the intervals of the plurality of locking holes 15. The same applies to the second screw member 407.

When the slider 12 is inserted into the rail 11 from the front, the foremost locking hole 15 of the rail 11 preferably has an extension (not shown in the drawings) that expands in width rearward.

The positions of the plurality of wheels 18 in the slider 12 relating to the sixteenth to eighteenth embodiments will now be described. As shown in fig. 48 and 49, the plurality of wheels 18 includes left and right front wheels 18A and left and right rear wheels 18B. The left and right front wheels 18A are disposed in front of the screw assembly 403 when viewed in the left-right direction. The left and right rear wheels 18B are arranged in a position overlapping the electric motor 404 when viewed in the left-right direction.

Since the left and right front wheels 18A are arranged so as to avoid the screw assembly 403 and the electric motor 404, an increase in the left-right width of the slider 12 can be suppressed.

Since the left and right rear wheels 18B are arranged in positions overlapping the electric motor 404 when viewed in the left-right direction, an increase in the front-rear length of the slider 12 can be suppressed.

In another embodiment, as shown in fig. 50, the plurality of wheels 18 may include left and right front wheels 18A, left and right rear wheels 18B, and left and right intermediate wheels 18C. Left and right front wheels 18A are preferably arranged at the front end of the slider 12 when viewed in the left-right direction. The left and right intermediate wheels 18C may be disposed in a position overlapping the screw assembly 403 when viewed in the left-right direction. The left and right rear wheels 18B are preferably disposed between the screw assembly 403 and the electric motor 404 when viewed in the left-right direction.

Since the left and right front wheels 18A are arranged in positions overlapping the screw assemblies 403 when viewed in the left-right direction, an increase in the front-rear length of the slider 12 can be suppressed.

Since the left and right rear wheels 18B are arranged between the screw assembly 403 and the electric motor 404 when viewed in the left-right direction, an increase in the front-rear length of the slider 12 can be suppressed. The left and right rear wheels 18B can be supported by using a space between the screw assembly 403 and the electric motor 404.

As shown in fig. 51, in another embodiment, the screw assembly 403 and the electric motor 404 may be arranged in reverse order with respect to the front-rear direction. That is, the electric motor 404 may be disposed in front of the screw assembly 403. In this case, the left and right front wheels 18A may be arranged in a position overlapping with the electric motor 404 when viewed in the left-right direction. Left and right rear wheels 18B are preferably disposed rearward of the threaded assembly 403.

In another embodiment, as shown in fig. 52, front and rear electric motors 404 may be disposed in front of and behind the screw assembly 403. In this case, preferably, the drive shaft 413 extends forward and rearward from the screw assembly 403 and is connected to the front and rear electric motors 404. The left and right front wheels 18A may be arranged in a position overlapping the front electric motor 404 when viewed in the left-right direction. Left and right rear wheels 18B are preferably disposed rearward of the threaded assembly 403. The front-to-back length of each of the front and back electric motors 404 is preferably longer than the front-to-back length of the screw assembly 403. Thereby, it is possible to increase the torque of the front and rear electric motors 404.

As shown in fig. 3, when viewed from above, a gap is formed between the rail inner side wall 11D of the rail 11 and the slider inner side wall 12B of the slider 12. Through this gap, the worker can view the first screw member 406 and the second screw member 407 from above. The upper portion of the protrusion 11G of the track inner side wall 11D and the upper portion of the recess 12E of the slider inner side wall 12B form parallel inclined surfaces opposed to each other. Thereby, intrusion of foreign matter into the gap between the slider inner side wall 12B of the slider 12 and the rail inner side wall 11D of the rail 11 is suppressed.

As shown in fig. 53, in another embodiment, at least one inspection window 481 penetrating the slider upper wall 12A in the up-down direction may be formed. The inspection window 481 is preferably disposed over at least one of the screw assembly 403, the electric motor 404, and the drive shaft 413. The worker can view the screw assembly 403 and the like through the inspection window 481.

As shown in fig. 54, the left and right sliders 12 may be connected to each other by a first line 501 and a second line 502. The first wire 501 connects the front end of the left slider 12 and the rear end of the right slider 12. The second wire 502 connects the front end of the right slider 12 and the rear end of the left slider 12.

The first wire 501 is wound around a first pulley 503 and a second pulley 504. The first pulley 503 is provided at the front end of the left rail 11, and the second pulley 504 is provided at the rear end of the right rail 11. The second wire 502 is wound around a third pulley 505 and a fourth pulley 506. The third pulley 505 is disposed at the front end of the right rail 11, and the fourth pulley 506 is disposed at the rear end of the left rail 11.

The first line 501 and the second line 502 extend to pass through the inside of the track 11. The first wire 501, the second wire 502, and the first to fourth pulleys 503 to 506 are preferably disposed under the floor 2. Due to the first wire 501 and the second wire 502, the left and right sliders 12 move in synchronization with each other. The first wire 501 and the second wire 502 may be other linear members such as a belt.

As shown in fig. 55, a sensor 510 for detecting tension may be provided between the left slider 12 and the first wire 501 and between the right slider 12 and the second wire 502. Preferably, the left and right electric motors 404 are controlled based on tension detected by the sensor 510. For example, the left and right electric motors 404 are preferably controlled to reduce the tension detected by the sensor 510.

As shown in fig. 56, a sensor 520 for measuring the rotational speeds of the left and right electric motors 404 may be provided. The left and right electric motors 404 are preferably controlled so that their rotational speeds become the same. Each sensor 520 may be, for example, a variable resistor, a rotary encoder, or a hall element. Further, the left and right rails 11 may be provided with slider position sensors for detecting the positions of the corresponding sliders 12.

As shown in fig. 57, a wire 530 is connected to the rear ends of the left and right sliders 12. The wires 530 extend back through the interior of the respective tracks 11. Behind the track 11, a reel 531 is provided on which the respective wire 530 is wound. The spool 531 is forced in the direction of the winding wire 530. Each spool 531 is provided with a variable resistor 532 for measuring the rotational speed. In this embodiment, the positions of the left and right sliders 12 are detected based on the rotational speeds of the left and right reels 531.

The electric slide rails 401, 450, 470 according to the above-described embodiments are provided in a vehicle 600 as shown in fig. 58 and 59. As shown in fig. 58, the vehicle 600 includes left and right front wheels 601, left and right rear wheels 602, and a cabin 603. In the vehicle cabin 603, a driver seat 605, a first seat 606, a second seat 607, and a third seat 608 are provided. The first seat 606 may be referred to as a front passenger seat, the second seat 607 may be referred to as a center seat, and the third seat 608 may be referred to as a rear seat.

The driver seat 605 is preferably provided in the left or right front portion of the vehicle cabin 603.

The second seat 607 is preferably disposed between the operator's seat 605 and the first seat 606. The third seat 608 is preferably disposed behind the operator's seat 605.

The power track 606A for the first seat 606, the power track 607A for the second seat 607, and the power track 608A for the third seat 608 may be any of the power tracks 401, 450, 470 described above.

The left and right rails 11 of the power slide rail 606A for the first seat 606 preferably extend in the front-rear direction from the front of the vehicle cabin 603 to the rear wheels 602. The rear ends of the left and right rails 11 of the electric slide rail 606A may be disposed rearward of the front ends of the rear wheels 602.

The left and right rails 11 of the power track 607A for the second seat 607 preferably extend in the front-rear direction from the front of the vehicle cabin 603 to the rear wheels 602. Rear ends of the left and right rails 11 of the electric slide rail 607A may be disposed rearward of front ends of the rear wheels 602.

The left and right rails 11 of the power slide rail 607A for the third seat 608 preferably extend in the front-rear direction from the rear of the driver seat 605 to the rear wheels 602. Rear ends of the left and right rails 11 of the electric slide rail 607A may be disposed rearward of front ends of the rear wheels 602.

Rear ends of the left and right rails 11 of each of the power slide rails 606A, 607A, 608A may be disposed at the rear end of the vehicle compartment 603.

As shown in fig. 59, the second seat 607 may be omitted. The left and right rails 11 of the electric slide rail 606A for the first seat 606 may be provided to be inclined with respect to the front-rear direction. For example, the left and right rails 11 of the power slide rail 606A for the first seat 606 may be inclined laterally inward toward the rear. The left and right rails 11 of the power slide rail 606A for the first seat 606 are preferably configured to avoid the wheel cover 611 of the rear wheel 602. The front end of one of the left and right rails 11 of the electric slide rail 606A for the first seat 606 is preferably disposed in front of the wheel cover 611 of the rear wheel 602.
