Description

  The present invention relates to a slide lock device that is disposed between a fixed member and a movable member to stop the rotation of the movable member.

  In an automobile, it is necessary to prevent the door from being automatically closed due to the inclination of the slope or its own weight, or the door from being closed due to the wind pressure, by maintaining the open state of the door. Moreover, in the center console provided in the vehicle interior, it is convenient to keep the door open and to easily take out the articles inside. The slide lock device is used to lock the rotation of such a movable member such as a door or a door.

  Patent Document 1 describes a conventional slide lock device for maintaining an open state of a door of an automobile. This device has a structure in which a plurality of raised portions are formed along the length direction on the upper and lower surfaces of a lever that is rotatably supported on the vehicle body side, and the raised portions pass through a holding member held on the door side. Yes. The holding member includes a slider that moves while sliding on the protruding portion of the penetrating lever, and an elastic body that urges the slider so as to press the protruding portion. In this slide lock device, the holding member moves along the length of the lever as the door opens, and during this movement, the slider rides on the protruding portion of the lever to compress the elastic body, and the reaction of compression Thus, the open state of the door is maintained by utilizing a sliding resistance generated between the slider and the lever.

  However, in the slide lock device of Patent Document 1, the door opening angle is only about two to three stages. This is because the door is kept open when it rides on the raised portion of the lever, and the door opening angle depends on the location of the raised portion. In such a structure, the door opening angle cannot be arbitrarily set, and there is a problem that it is inconvenient for raising and lowering the automobile. Moreover, the door opening operation force cannot be reduced, and there is a problem that the operability is poor. Such a problem applies not only to automobile doors but also to other devices that need to keep the movable member open.

  On the other hand, Patent Documents 2 and 3 describe a slide lock device that can stop the opening angle of a door or the like steplessly.

  In the slide lock device described in Patent Document 2, a door-side slide member is movably attached to a vehicle body-side lever plate, and a leaf spring that contacts the lever plate and generates a frictional force is provided on the slide member. The lever plate is stopped at an arbitrary position in the length direction. Thereby, it becomes possible to stop the door opening angle steplessly. Further, the release member is provided on the slide member, and the release member is inserted between the leaf spring and the lever plate to release the stop. In such a structure, the movement of the slide member, that is, the opening operation of the door (movable side member) can be stopped steplessly by the frictional force of the leaf spring, and the release member can release the stop state. .

  The slide lock device described in Patent Document 3 has a structure in which a door open position holding mechanism and a door lock mechanism are provided. The door open position holding mechanism is a mechanism that holds the door in an open state by friction resistance between a raised portion provided on the lever and a slider that slides the lever, and by applying a force greater than the friction resistance to the door. The door can be opened and closed. The door lock mechanism locks the door at an arbitrary angle by stopping the cylinder at an arbitrary position by winding a reversely wound coil spring around the cylinder moving along the rod and expanding and contracting the coil diameter of the coil spring by lever operation. It has a structure.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In each embodiment, the same member is assigned the same reference numeral.

(First embodiment)
1 to 8 show a slide lock device 1 according to a first embodiment of the present invention. The slide lock device 1 is applied to, for example, an automobile door. 1 to 3 are states before the slide lock device 1 is operated, FIG. 4 is a state applied to the door 13 of the automobile, FIGS. 5 and 6 are movement states of the slide member 3, and FIGS. 7 and 8 are cable tension adjustments. The operation of the mechanism 7 is shown respectively.

  The slide lock device 1 includes a lever plate 2, a slide member 3, a shaft body 4, a cable 5, and a tension applying mechanism 7.

  The lever plate 2 is formed by a long plate-like plate main body 2a, and a first bent portion 2b and a second bent portion 2c bent in the same direction from both ends in the length direction of the plate main body 2a. One end (first bent portion 2b) of the lever plate 2 is attached to a vehicle body 12 (see FIG. 4) as a stationary member, and the other end (second bent portion 2c) is in a free state. In order to perform attachment to the vehicle body 12, the attachment bracket 11 is attached to the first bent portion 2b. The mounting bracket 11 is fixed to the vehicle body 12, and the lever plate 2 is rotatably mounted on the pivot pin 15 of the mounting bracket 11.

  As shown in FIG. 4, in the automobile, the door 13 that is a movable member can rotate forward and backward with respect to the vehicle body 12 that is a stationary member, and the door 13 is opened and closed by this forward and reverse rotation. In FIG. 4, reference numeral 14 denotes a door rotation shaft serving as the rotation center of the door 13 with respect to the vehicle body 12, and the pivot pin 15 serving as the rotation center of the slide lock device 1 has a position different from that of the door rotation shaft 14. It has become. By opening and closing the door 13, the door 13 rotates forward and backward around the door rotation shaft 14, whereas the slide lock device 1 rotates forward and backward around the pivot pin 15 as the door 13 opens and closes. . As shown in FIG. 4, the door 13 is opened and closed within the range of the angle A, the solid line is the fully closed position of the door 13, and the chain line is the fully open position of the door 13.

  The slide member 3 moves along the length direction of the plate body 2 a in the lever plate 2. The slide member 3 is formed by a contact bracket portion 3a and a holding bracket portion 3b assembled to the contact bracket portion 3a. The abutting bracket portion 3a is fixed to the inner wall of the door 13 by bolts, welding or the like. When the door 13 is opened and closed, the contact bracket portion 3 a receives the opening and closing force of the door 13, so that the entire slide member 3 reciprocates with respect to the lever plate 2. The holding bracket portion 3b fixes the shaft body 4, and the shaft body 4 is attached while being sandwiched between the holding bracket portions 3b.

  The shaft body 4 is formed by a bobbin portion 4a having a circular outer shape and shaft portions 4b at both ends of the bobbin portion 4a. A cable 5 is wound around the bobbin portion 4a. The shaft portions 4b at both ends of the bobbin portion 4a penetrate the holding bracket portion 3b of the slide member 3, and the penetrating ends of one shaft portion 4b are crimped. Thereby, the shaft body 4 is a fixed shaft fixed to the slide member 3.

  The cable 5 is wound around the bobbin portion 4a of the shaft body 4, and is arranged so as to be pulled out from both sides of the bobbin portion 4a in this wound state. For this reason, the cable 5 has the winding part 5a wound around the shaft body 4, and the left and right cable parts 5b and 5c extending from both sides of the shaft body 4 in a state of being continuous with the winding part 5a. The cable portions 5 b and 5 c on both sides of the shaft body 4 extend linearly along the length direction of the lever plate 2, and the end portion 5 d of one cable portion 5 b located on the left side is the first bent portion of the lever plate 2. The end portion 5e of the other cable portion 5c that is locked to the outside of the portion 2b and located on the right side is locked to the outside of a tension applying mechanism 7 described later.

  In this structure, when the left and right cable portions 5b and 5c are in a tension state in which they are pulled in a straight line, the winding portion 5a of the cable 5 applies a frictional force to the shaft body 4, and the winding portion 5a is the shaft body 4. The movement of the shaft body 4 (that is, the slide member 3) is stopped at an arbitrary position by the frictional force applied to.

  When a moving force that is greater than the frictional force of the winding portion 5a around the shaft body 4 is applied to the slide member 3 with respect to such a stopped movement state of the slide member 3, the tension of the cable portion 5b or 5c on the direction side becomes loose. Accordingly, since the winding state of the winding portion 5a around the shaft body 4 is also loosened, the slide member 3 can be forcibly moved in that direction. For example, by applying a rightward movement force on the slide member 3 that is equal to or greater than the frictional force of the wrapping portion 5a, the tension state of the other cable portion 5c on the right side is loosened. As a result, the winding of the winding portion 5a around the shaft body 4 is loosened and the frictional force is reduced. Therefore, the slide member 3 can be forcibly moved from the position shown in FIGS. 1 and 2 to the position shown in FIGS. 5 and 6 and the door 13 can be opened.

  Then, when the moving force on the slide member 3 is released at the position of FIGS. 5 and 6, the other cable portion 5 c on the right side is in a tension state similar to the one cable portion 5 b on the left side, and the winding portion 5 a is attached to the shaft body 4. Since the acting frictional force is restored, the slide member 3 is stopped at that position by the frictional force applied to the shaft body 4 of the winding portion 5a. In these structures, since the movement of the slide member 3 can be stopped at an arbitrary position, the opening angle of the door 13 (movable side member) can be stopped steplessly. In order to apply the frictional force having such a function, the winding portion 5a is wound around the bobbin portion 4a of the shaft body 4 in two or more turns.

  The tension applying mechanism 7 is disposed on the second bent portion 2 c side of the lever plate 2. As shown in FIGS. 7 and 8, the tension applying mechanism 7 includes a cam case 7a fixed to the outer surface of the second bent portion 2c, a tension cam member 7b accommodated in the cam case 7a, a return spring 9, and a cam case. And an operation member 8 drawn outward from 7a. In this case, the other cable portion 5 c penetrates the tension applying mechanism 7.

  The tension cam member 7b is formed by a rotation cam 7c, a slide cam 7d facing the rotation cam 7c, and a lock piece 7g provided on the slide cam 7d side. The opposing surfaces of the rotating cam 7c and the slide cam 7d are cam surfaces 7e inclined toward the end 5e of the other cable portion 5c. An inclined surface 7f is formed on the inner surface of the cam case 7a. The inclined surface 7f has an inclined diameter that gradually decreases toward the end 5e of the other cable 5c. The lock piece 7g is provided between the slide cam 7d and the end portion 5e of the other cable portion 5c, and a plurality of lock pieces 7g are arranged on the circumference centering on the other cable portion 5c. Each lock piece 7g is provided so as to slide on the slope 7f, and operates to approach or separate from the other cable portion 5c by sliding in the reciprocating direction along the slope 7f. Then, the other cable portion 5c is sandwiched and held by approaching the other cable portion 5c, and the holding is released by moving away from the other cable portion 5c.

  The return spring 9 urges the lock piece 7g and the slide cam 7d to return to the rotating cam 7c side. FIG. 7 shows a normal state, in which the slide cam 7d is positioned on the rotating cam 7c side, and the lock piece 7g is separated from the other cable portion 5c. In the state shown in FIG. 7, the lock piece 7g is urged away from the other cable part 5c by the return spring 9, so that the lock piece 7g does not sandwich the other cable part 5c. The operating member 8 is connected to the rotating cam 7c, and rotates the rotating cam 7c by the rotating operation. Then, the rotation cam 7c pushes the slide cam 7d and moves in the direction of the end 5e of the other cable portion 5c by the rotation operation in one direction, so that the tension cam member 7b is extended. 7g pinches the other cable portion 5c, and the lock piece 7g moves in the extending direction. By this movement, the other cable portion 5c is linearly pulled in the right direction away from the winding portion 5a wound around the bobbin portion 4a, so that the other cable portion 5c is in a tension state and this tension state is locked. . When the operation member 8 is rotated in the opposite direction, the pushing of the slide cam 7d by the rotating cam 7c is released, so that the slide cam 7d returns to the original state by the urging force of the return spring 9 and the other cable by the lock piece 7g. The pinching of the part 5c is released.

As shown in FIGS. 7 and 8, the other cable portion 5c passes through the rotating cam 7c, the slide cam 7d and the lock piece 7g and is drawn to the outside of the cam case 7a, and the drawn end portion 5e is the cam case 7a. Is locked to the outer surface.

In the state of FIG. 7, the operating member 8 is operated to rotate the rotating cam 7c, and the slide cam 7d is moved so as to approach the end 5e of the other cable portion 5c. By moving in this direction, the tension cam member 7b is extended, and the lock piece 7g sandwiches the other cable portion 5c and pulls the other cable portion 5c linearly to make the tension state. Lock it. Thus, when the tension state of the other cable part 5c is locked, the slide member 3 cannot move to the end part 5e side (the opening direction of the door 13) of the other cable 5c, and the slide member 3 moves. Is forcibly locked. For this reason, even if a strong wind is received when the door is released, the vehicle stops on a slope, or even if a person leans on the door, the door 13 secures its position, which is safe.

  In this case, the lock member 7 is forcibly locked via the slide member 3 by applying a force larger than the lock force of the tension applying mechanism 7 to the door 13 without operating the operation member 8. It can be canceled. Therefore, it is possible to perform a throw door operation in an emergency such as a vehicle collision.

  When the operating member 8 is operated in the state of FIG. 8 to rotate the rotary cam 7c in the opposite direction, the slide cam 7d is separated from the end 5e of the other cable portion 5c and is in the state of FIG. 7 is released, and the other cable portion 5c on the left side returns to the state before the tension applying mechanism 7 does not operate. For this reason, the slide member 3 stops moving based on the tension state of the left and right cable portions 5b and 5c and the frictional force of the winding portion 5a around the shaft body 3 as described above.

  1 to 3 show a state in which the door 13 is closed. When the door 13 is rotated and opened in this state, the slide member 3 is pushed by the rotation of the door 13, so that the slide member 3 moves along the lever plate 2. Move left. 5 and 6 show the slide member 3 when the door 13 is opened. In the movement of the slide member 3, the shaft body 4 moves integrally with the slide member 3 while the winding position with respect to the shaft body 4 changes. At this time, the shaft body 4 is a fixed shaft fixed to the slide member 3, and the winding portion 5 a of the cable 5 applies a frictional force to the shaft body 4. As described above, when the left and right cable portions 5b and 5c are in tension, when the opening of the door 13 is stopped, the sliding member 3 stops moving at that position by the frictional force of the winding portion 5a. Thereby, since the door 13 stops at the opening angle, the door 13 can be stopped at an arbitrary angle, and the opening of the door 13 can be stopped steplessly. When the door 13 is further opened or rotated to close the door 13 in this state, the slide member 3 moves in a direction corresponding to the rotational direction against the frictional force on the shaft body 4 of the winding portion 5a. . Therefore, the door 13 can be opened and closed smoothly. In this embodiment, as described above, the opening operation of the door 13 can be firmly stopped by operating the tension applying mechanism 7 and tension-locking the other cable portion 5c.

  In such an embodiment, since the movement of the slide member 3 stops at an arbitrary position due to the frictional force of the winding portion 5a of the cable 5 wound around the shaft body 4 provided on the slide member 3, the door 13 (movable side member) ) Can be stopped steplessly. In addition, since the door 13 (movable side member) is opened and closed by the frictional force of the cable 5 wound around the shaft body 4, it can be opened and closed simply by winding the cable 5 around the shaft body 4. Is not required, the assembly is facilitated, and the cost can be reduced.

(Second Embodiment)
9 to 13 show a slide lock device 1A according to the second embodiment of the present invention. FIGS. 9 to 11 show a state before the operation, and FIGS. 12 and 13 show a movement state of the slide member 3. FIG.

  The slide lock device 1A of this embodiment has a structure provided with a friction mechanism 17 that makes the shaft body 4 a rotatable movable shaft and restricts the rotation of the shaft body 4 within a predetermined friction force range. Further, the tension applying mechanism 7 is omitted from the slide lock device 1 of the first embodiment. Other structures are the same as those of the slide lock device 1 of the first embodiment.

  In the shaft body 4 of this embodiment, in addition to the shaft portions 4b at both ends of the bobbin portion 4a being rotatably inserted into the holding bracket portion 3b of the slide member 3, one shaft portion 4b (in the illustrated example, on the upper side) The shaft portion 4b) extends in a direction perpendicular to the slide member 3, and a friction mechanism 17 is provided on the extended shaft portion 4b side.

  The friction mechanism 17 includes a friction plate 17a, an elastic body 17b made of a disc spring, a push plate 17f, a slide cam 17c, and a rotary cam 17d that are housed in a case 17g in a state in which they are sequentially arranged as they move away from the slide member 3. It has become. The rotating cam 17d is rotated, and a lever 17e for performing the rotating operation is attached to the rotating cam 17d.

The friction plate 17a is attached to one shaft portion 4b while being rotationally restrained by one shaft portion 4b of the shaft body 4. The elastic body 17b presses the friction plate 17a to apply a frictional force to the friction plate 17a. When the frictional force of the elastic body 17b is equal to or greater than a predetermined value, the rotation of the friction plate 17a is constrained. The body 4 is rotationally restrained. On the other hand, when the frictional force of the elastic body 17b is equal to or less than a predetermined value, the friction plate 17a can rotate and the shaft body 4 can rotate.

The rotating cam 17d is formed with an inclined cam surface 17h rising toward the friction plate 17a, and the slide cam 17c is in contact with the cam surface 17h. The slide cam 17c moves along one shaft portion 4b of the shaft body 4 by rotating the rotating cam 17d by operating the lever 17e. By this movement, the pressing force of the slide cam 17c acting on the elastic body 17b via the push plate 17f changes, and the rotation restraint and the rotatable ability of the shaft body 4 can be switched.

  9 to 11 show a state in which the lever 17e is not operated, and the elastic body 17b is weakly pressed by the slide cam 17c, and the elastic body 17b causes the friction plate 17a to exert a friction force of a predetermined value or less. ing. In this state, the shaft body 4 is rotatable with respect to the slide member 3. Therefore, the slide member 3 can be moved with a small force.

  12 and 13 show a state where the lever 17e is operated to rotate the rotary cam 17d and the slide cam 17c is moved in the direction of the elastic body 17b while the slide member 3 is being slid. In this state, the pressing force of the slide cam 17c against the elastic body 17b is increased, and the elastic body 17b applies a predetermined or higher frictional force to the friction plate 17a. Thereby, the shaft body 4 is rotationally restrained, and the shaft body 4 becomes the same as the fixed shaft in the first embodiment. In this state, the shaft member 4 is the same as that of the first embodiment in which the shaft 4 is a fixed shaft, and the slide member 3 is moved by the frictional force on the shaft member 4 of the winding portion 5a in the tension state of the left and right cable portions 5b and 5c. Stopped. Further, when the moving force more than the frictional force of the winding portion 5a to the shaft body 4 is applied to the slide member 3, the slide member 3 moves in that direction.

  In such an embodiment, in addition to obtaining the same effect as the first embodiment, the shaft body 4 can be changed to a rotatable movable shaft state, and the shaft body 4 can be rotated. Thus, the slide member 3 can be moved with a small force.

(Third embodiment)
14 to 18 show a slide lock device 1B according to a third embodiment of the present invention. FIGS. 14 to 16 show a state before operation, and FIGS. 17 to 20 show a movement state of the slide member 3. FIG.

  The slide lock device 1 </ b> B of this embodiment is provided with two elastic members 6 and 16 for the cable 5, and the elastic members 6 and 16 are disposed at both ends of the cable 5. Each of the elastic member members 6 and 16 uses a compression spring. Hereinafter, the elastic member 6 will be described as the first elastic member 6, and the elastic member 16 will be described as the second elastic member 16. In this embodiment, the tension applying mechanism 7 of the first embodiment is omitted, and the shaft body 4 is a fixed shaft fixed to the slide member 3.

  The first elastic member 6 is disposed so as to be positioned on the other cable portion 5 c side on the right side of the cable 5, and is provided so as to contact the outer surface of the second bent portion 2 c on the other side of the lever plate 2. It has been. The other cable portion 5 c passes through the second bent portion 2 c and the first elastic member 6, and an end portion 5 e of the cable portion 5 c is locked to the outside of the first elastic member 6. Thereby, the first elastic member 6 applies tension to the other cable portion 5c to be in a tension state, and prevents the other cable portion 5c from being loosened.

  The second elastic member 16 is disposed so as to be positioned on the left one cable portion 5 b side of the cable 5. The second elastic member 16 is provided so as to contact the outer surface of the first bent portion 2 b on one side of the lever plate 2, and the one cable portion 5 b penetrates the first bent portion 2 b and the second elastic member 16. The end 5d is locked and fixed to the outside of the second elastic member 16. Thereby, the 2nd elastic member 16 makes tension state act on one cable part 5b, and is preventing it from loosening one cable part 5b.

  Thus, by providing the elastic members 6 and 16 with respect to both ends of the cable 5, it is possible to maintain a tension state in which both the left and right cable portions 5b and 5c extend linearly. In the tension state of the left and right cable parts 5b and 5c, the movement of the slide member 3 is stopped by the frictional force that the winding part 5a of the cable 5 acts on the shaft body 4, and the opening and closing of the door 13 (movable side member) is stopped. It will be in the state. When a moving force equal to or greater than the frictional force applied to the shaft body 4 of the winding portion 5a is applied to the slide member 3 with respect to the stopped state of the movable member, the slide member 3 moves.

  That is, as shown in FIGS. 17 and 18, when a moving force in the direction of the other cable portion 5c (first elastic member 6) on the right side is applied to the slide member 3, the one cable portion 5b is moved in the same direction. When pulled, the second elastic member 16 is bent and the other cable portion 5c on the right side of the shaft body 4 is relaxed. For this reason, the slide member 3 can be moved to an arbitrary position in the direction of the arrow A. On the other hand, as shown in FIGS. 19 and 20, when a moving force in the direction of the left cable portion 5b is applied to the slide member 3, the operation is reversed, and the slide member 3 moves in the arrow B direction. be able to. In these movements, by releasing the moving force, the cable portions 5b and 5c are returned to the tension state by the biasing force of the elastic members 6 and 16, and the slide member 3 is moved to its position by the frictional force of the winding portion 5a around the shaft body 4. Stop at. For this reason, the door 13 stops at the opening angle, and the opening of the door 13 can be stopped steplessly. When the door 13 is further opened or the door 13 is closed, an opening / closing force greater than the frictional force of the winding portion 5a acting on the shaft body 4 is applied to the door 13.

  In such an embodiment, each of the left and right cable portions 5b and 5c is maintained in a tension state by the elastic members 6 and 16, and the winding portion 5a is reliably wound around the shaft body 4. Inadvertent movement can be prevented, and a stable movement stop state can be achieved. The left and right elastic members 6, 16 may have the same spring force or different spring forces. In the latter case, the moving force of the slide member 3 in any one direction is different from the moving force of the slide member 13 in the other direction. For example, the moving force in the other direction with respect to the moving force in one direction. Therefore, the door 13 can be closed or opened freely. In addition, the elastic members 6 and 16 should just be provided in one of the cable parts 5b and 5c, and do not need to be provided in both cable parts 5b and 5c.

The shaft body 4 is a fixed shaft fixed to the slide member 3.

  In this embodiment, when the tension imparting mechanism 7 is not operating, it operates similarly to the slide lock device 1B of the third embodiment. That is, the left and right cable members 5b and 5c maintain a tension state in which the left and right cable portions 5b and 5c extend linearly by the left and right elastic members 6 and 16, respectively. The movement of the slide member 3 is stopped by the frictional force that the part 5a acts on the shaft body 4, and the opening and closing of the door 13 (movable side member) is stopped. When a moving force equal to or greater than the frictional force applied to the shaft body 4 of the winding portion 5a is applied to the slide member 3 with respect to the stopped state of the movable member, the slide member 3 moves.

  On the other hand, when the tension applying mechanism 7 is activated, that is, the operating member 8 is rotated to operate the tension cam member 7b, the other cable portion 5c is sandwiched by the lock piece 7g, and the other cable portion 5c is Assuming that the cable 5 is pulled away from the winding portion 5a, the other cable portion 5 is locked in a tension state regardless of the first elastic member 6. Thus, the slide member 3 can be forcibly locked at the stop position, and the door 13 can be locked at an arbitrary opening angle (FIGS. 24 and 25).

(Fifth embodiment)
26 to 30 show a slide lock device 1D according to the fifth embodiment of the present invention. FIGS. 26 to 28 show a state before operation, and FIGS. 29 and 30 show a movement state of the slide member 3. FIG.

A cam surface 18e and a cam that are inclined in a rising direction toward the elastic member 6 are provided on a surface of the rotating cam 18c facing the slide cam 18d. A top surface 18f continuous to the top of the surface 18e is formed, and a cam projection 18g facing the cam surface 18e is formed on the slide cam 18d. The other cable part 5c penetrates the rotary cam 18c and the slide cam 18d and penetrates the elastic member 6, and its end part 5e is locked to the outer end surface of the elastic member 6.

In the tension increasing mechanism 18, the cam protrusion 18g contacting the cam surface 18e contacts the top surface 18f by operating the operation lever 18h to rotate the rotating cam 18c. As a result, as shown in FIGS. 29 and 30, the rotary cam 18 c and the slide cam 18 d are in the most distant state, and the entire tension increasing mechanism 18 is extended to bend the elastic member 6. When the elastic member 6 is bent, the tension state of the left portion of the tension increasing mechanism 18 in the other cable portion 5c is strengthened. That is, since the elastic member 6 is bent and the spring force is changed by operating the tension increasing mechanism 18, the tension state of the other cable portion 5 c is stronger than the tension state of the other cable portion 5 c before the tension increasing mechanism 18 is operated. Can be changed. For this reason, it becomes possible to change the stopping force of the slide member 3, that is, the locking force.
In this case, the slide member 3 can be slid by applying a force on the slide member 3 that is greater than or equal to the spring force of the elastic member 6 changed by the operation of the tension increasing mechanism 18.
