The interval between the front rod 14 and the rear rod 15 of the striker 11 is wider than the interval between the first-stage engagement groove 24 and the second-stage engagement groove 26, and the rear rod 15 is in the first-stage engagement. When engaged with the mating groove 24, the front rod 14 has a gap with the inner periphery of the second stage engaging groove 26.

That is, the distance T between the front rod 14 and the rear rod 15 of the striker 11 is between the front inner peripheral surface 28 of the first step engagement groove 24 and the rear inner peripheral surface 29 of the second step engagement groove 26. The distance T ′ is wider than the distance T ′, and is narrower than the distance t between the front inner circumferential surface 28 of the first stage engaging groove 24 and the inner inner circumferential surface 31 of the second stage engaging groove 26.
The side surface of the engagement member 20 is provided with a shaft-shaped engagement body 35 protruding rearward. The engagement body 35 is provided with an engagement surface 37 of an opening member (operation transmission means) 36 between the engagement body 35 and the engagement body 35. The gap 38 is provided. The opening member 36 is rotatably attached to the body 10 and the cover 40 by a shaft 39. One end of an operation transmission member 41 is attached to the opening member 36, and the other end of the operation transmission member 41 is locked to an operation member 42 such as an arbitrary knob or handle.

Below the striker entry groove 12 of the cover 40, a stopper surface 45 is formed to which the lower part of the lowest front inner peripheral surface 28 of the engagement member 20 abuts (FIG. 3).
Since the stopper surface 45 is formed by bending the cover 40 to be attached to the body 1, it is only necessary to attach the cover 40 to the body 1, and manufacturing and assembly are easy.

In this case, the one side insertion hole 110 and the other side insertion hole 111 are formed wider in the front / rear / left / right direction than the wire diameter of each inner cable 101, and each inner cable is moved when the operation transmitting means 36 moves. 101 moves in the one-side insertion hole 110 and the other-side insertion hole 111 in the front-rear and left-right directions, so that the operation transmitting means 36 can be smoothly rotated.

In order for each inner cable 101 to smoothly move back and forth and right and left in the one side insertion hole 110 and the other side insertion hole 111, the inner peripheral surfaces of the one side insertion hole 110 and the other side insertion hole 111 are all in plan view. The upper and lower corners are formed in the arc portion 113A over the circumference, and wear and breakage of each inner cable 101 is suppressed and prevented. Also in the cross section, the one side insertion hole 110 and the other side insertion hole 111 are formed in the inner peripheral circular arc portion 113B so that a so-called edge does not occur in the inner peripheral upper and lower corners over the entire circumference, and wear of each inner cable 101・ Suppress and prevent damage.
Further, each of the one side insertion hole 110, the other side insertion hole 111, and the engagement groove 112 is formed to be smaller than the diameter of the tip engagement portion 104, and only the center of the fitting hole 113 is provided at the tip engagement portion. 104 is configured to pass through.

The cable locking portion 105 bends the engaging plate portion 116 at approximately 90 degrees at the tip of the base plate portion 115. The engaging plate portion 116 is provided with a counter plate portion 117 substantially parallel to the base plate portion 115. The engagement plate portion 116 is formed with the one side insertion hole 110 and the other side insertion hole 111.
The opposing plate portion 117 has an engagement groove 112 communicating with the one side insertion hole 110 and the other side insertion hole 111, and a fitting hole that communicates with the engagement groove 112 and can be fitted with the tip engagement portion 104. 113.
In the embodiment, the engagement groove 112 of the one-side insertion hole 110 and the engagement groove 112 of the other-side insertion hole 111 are communicated so as to intersect at the lower side, and a fitting hole 113 is provided at the center of the left and right engagement grooves 112. ing.
The outer locking portion 103 is provided at a predetermined position of the device L above in the tangential direction with respect to the rotation trajectory of the engagement plate portion 116 of the cable locking portion 105.

That is, the outer locking portion 103 is the body 1 or the upper position in the crossing direction with respect to the moving direction of the cable locking portion 105 of the operation transmitting means 36 when the operating member 20 moves from the latched state to the unlatched state. Provided on the cover 40.
In the embodiment, the outer locking portion 103 is provided on the cover 40.
The outer locking portion 103 is provided with an engagement groove 121 that locks the attachment member 120 at the end of the outer tube 100 so as to face the one side insertion hole 110 and the other side insertion hole 111.
The base plate portion 115 and the counter plate portion 117 of the cable locking portion 105 are provided at a predetermined interval on the left and right.
That is, the cable locking portion 105 is configured to be rotatable upward with respect to the distal end engaging portion 104 that is in contact with the lower surface of the engaging plate portion 116.

Further, the main body 123 of the operation transmission means 36 is formed to a thickness that does not interfere with the distal end engaging portion 104 that moves to the side opposite to the cable locking portion 105 from the engaging plate portion 116.
That is, when the main body 123 of the operation transmission means 36 is rotated upward by an unlatching operation, the main body 123 is rotated upward while maintaining the disengaged state of the tip engaging portion 104 that remains without being operated. The thickness is set so as not to interfere with the front end engaging portion 104 moving to the side opposite to the cable locking portion 105 from the engaging plate portion 116.
The main body 123 of the operation transmission means 36 facing the engagement plate portion 116 is formed with an inclined surface 124 that is low on the engagement plate portion 116 side and increases as the distance from the engagement plate portion 116 increases. The inclined surface 124 smoothly rotates the main body 123 of the operation transmission means 36 while leaving the tip engaging portion 104 remaining without being operated.

Thus, the operation mechanism of the device of the operation transmission member 41 can be used (applied) to various devices. In the present application, the device L is provided between the back sheet 6 of the seat 1 and the fixing portion 3. In addition, a latch device L is provided for holding the dorsal seat 6 in a predetermined position.
The actuating member 20 actuated by the actuating transmission means 36 is an engaging member 20 that engages with the striker 11 fixed to the fixing portion 3.
The cable locking portion 105 is formed by bending a metal plate member, and one side insertion hole 110 to fitting hole 113 is formed in the metal plate member, and the cable transmitting portion 105 is formed of a resin member. The body 123 is integrally formed.
Therefore, one end of the cable 41A connected to the one side operation member 42A provided at a predetermined position away from the backrest seat 6 and the other end provided on the backrest seat 6 are connected to the cable locking portion 105 of the operation transmitting means 36. The front end engaging portion 104 of each inner cable 101 with the other side cable 41B connected to the side operation member 42B is locked, and the reclining or lying down operation of the dorsal seat 6 can be performed from two places.

(Operation of Example)
When seatback 6 is rotated forward to axis 7 around Mounting the upper portion relative to the vehicle body 3 from the normal seating position, the rear surface of the backrest seat 6 is a substantially flat, to increase the vehicle compartment space.
Further, the latch device L can be unlatched from the normal seating position, and can be tilted slightly rearward from the reclining position tilted from the normal seating position.
For example, when the dorsal seat 6 in the forward-turned state in which the striker 11 is not engaged with the latch device L in the unlatched state is raised, the striker 11 enters the striker entry groove 12 of the body 1, and the striker 11 The inclined guide surface 22 contacts the inclined guide surface 22 and guides the engaging member 20 to rotate upward about the engaging member mounting shaft 21 against the spring 55, and the front rod 14 of the striker 11 is inclined and guided. When passing through the surface 22 and below the first stage engagement groove 24, the engagement member 20 is engaged with the front rod 14 of the striker 11 by the elasticity of the spring 55.

Therefore, when the dorsal seat 6 is erected, the engagement member 20 can be engaged with the striker 11 without holding any operation, and the dorsal seat 6 can be held in the normal position. Improve operability.
Another second stage engagement groove 26 is formed on the engagement member mounting shaft 21 side of the first stage engagement groove 24 of the engagement member 20, and the other end of the engagement body 35 of the engagement member 20 is arbitrary. Since the engagement surface 37 of the release member 36 that is locked to the operation member 42 such as a knob is exposed, when the release member 36 is moved upward by the operation transmission member 41, the engagement surface of the release member 36 37 rotates the engaging body 35 upward about the engaging member mounting shaft 21, whereby the engaging member 20 rotates upward about the engaging member mounting shaft 21, and the striker 11 is moved from the first stage engaging groove 24. The front rod 14 can be detached.

Since the engagement surface 37 of the release member 36 is provided with a predetermined gap 38 between the engagement body 35 and the engagement surface 37 of the release member 36 is rotated by a predetermined amount, the engagement surface 37 contacts the engagement body 35. Rotate.
Therefore, even if there is a difference in length caused by a manufacturing error between the engagement surface 37 and the operation member 42, the gap 38 absorbs this, and the operation member 42 can always be positioned at a certain position. And the operation is transmitted reliably.
Next, in this state, when the dorsal seat 6 is tilted rearward, the front rod 14 and the rear rod 15 of the striker 11 enter toward the back side of the striker entry groove 12, and the rear rod 15 is engaged. When the operation member 42 is released after coming into contact with the inner peripheral surface 31 at the back of the second-stage engagement groove 26 of the member 20, the engagement member 20 is moved by the elasticity of the spring 55 to the first-stage engagement groove. side rod 15 after the striker 11 engages the 24, the front rod 14 is loosely fitted in the striker 11 to the second stage engaging grooves 26, backrest seat 6 is held in Rikurainin grayed position.

In this case, the front inner peripheral surface 28 of the first stage engaging groove 24 is inclined in a straight line or an arc shape so as to become the rear side as it goes downward in the engaged state, so that the rear inner peripheral surface 27 and the front side are inclined. Since the front-rear width of the inner peripheral surface 28 is formed narrower upward, the rear rod 15 causes the striker 11 to leave a gap above the first stage engaging groove 24 and the rear inner peripheral surface 27 and the front inner surface. Abuts and engages both of the peripheral surfaces 28.
Therefore, the “gap” that the striker 11 moves back and forth with respect to the engaging member 20 and the generation of abnormal noise are prevented.
Further, when the dorsal seat 6 is in the reclining state, the front rod 14 of the striker 11 does not come into contact with either the rear inner peripheral surface 29 or the rear inner peripheral surface 31 of the second-stage engagement groove 26. "And" prevent the generation of abnormal noise.

The first stage engaging groove 24 of the engaging member 20 has a rear inner peripheral surface 27 located on the striker 11 side and a front inner peripheral surface 28 located on the engaging member mounting shaft 21 side. Since the lower end of the surface 28 is formed so as to be positioned below the lower end of the rear inner peripheral surface 27, the striker 11 contacts the inclined guide surface 22, and the striker 11 is rotated while the engaging member 20 is rotated upward. When strikes and passes through the lower end of the rear inner peripheral surface 27, the striker 11 always hits the front inner peripheral surface 28.
Accordingly, when the dorsal seat 6 is erected, not only the engagement operation is unnecessary, but also the first-stage engagement groove 24 is always engaged.

Since the front inner circumferential surface 28 is inclined linearly or arcuately so as to become the rear side as it goes downward, the engagement member 20 is rotated upward from the engagement state with the striker 11 to the non-engagement state. At this time, the front inner circumferential surface 28 is separated from the striker 11. Accordingly, the striker 11 and the engaging member 20 are separated without changing the relative positions, so that the operation load is not increased during the non-engaging operation.
That is, when the front inner peripheral surface 28 is inclined to the front side as opposed to the embodiment, the front inner peripheral surface 28 is released while pushing the striker 11, so that it moves while pushing the back of the seated person. Therefore, the operation load becomes heavier, but this is eliminated.

The lower part of the front inner peripheral surface 28 is lower than the lower part of the rear inner peripheral surface 29 of the second stage engaging groove 26, and the lower part of the front inner peripheral surface 28 and the rear inner peripheral surface 29 of the second stage engaging groove 26 are arranged. Since the gap is inclined so as to increase toward the rear side, even if the engagement member 20 vibrates up and down in an engaged state due to an unforeseen cause, the second stage is separated from the first stage engagement groove 24. The engaging groove 26 is not engaged.
Further, since the space between the lower portion of the front inner peripheral surface 28 and the rear inner peripheral surface 29 of the second stage engaging groove 26 is inclined to reach the rear side, the second stage engaging groove 26 is provided. When the striker 11 is disengaged, the striker 11 passes through the lower part of the lowest front inner peripheral surface 28 and does not engage with the first-stage engagement groove 24, so that the striker 11 is brought into a free state in one motion.

Further, the lower part of the front inner peripheral surface 28 is lower than the lower part of the rear inner peripheral surface 29 of the second stage engaging groove 26, and the lower part of the front inner peripheral surface 28 and the rear inner part of the second stage engaging groove 26. since between the peripheral surface 29 is inclined so as to be higher in accordance reach the rear and is brought into contact with the bottom of the lowest front inner peripheral surface 28 of the engagement member 20 on the upper surface of the stopper surface 45, the scan Toraika 11 Makes the engaging member 20 stand by at the standby position so that the engaging member 20 contacts the inclined guide surface 22 and rotates the engaging member 20 upward.
Therefore, not only is the operation for engaging with the inclined guide surface 22 unnecessary when raising from the lying upper body, but the engaging member 20 is also caused by the action of the stopper surface 45 and the spring 55 when lying down from the standing state. The initial automatic return is performed, and the engagement standby operation is also unnecessary.

  Thus, the interval between the front rod 14 and the rear rod 15 of the striker 11 is wider than the interval between the first-stage engagement groove 24 and the second-stage engagement groove 26 of the engagement member 20. When the rod 15 engages with the first stage engaging groove 24, the front rod 14 has a gap between the inner periphery of the second stage engaging groove 26, so that the engaging member 20, the striker 11, Can be achieved by engaging the front rod 14 or the rear rod 15 with the first stage engagement groove 24, and the front rod 14 fits with respect to the second stage engagement groove 26. Therefore, it is possible to improve the certainty for preventing the occurrence of “ra” and abnormal noise.

In other words, the distance T between the front rod 14 and the rear rod 15 of the striker 11 is between the front inner peripheral surface 28 of the first step engagement groove 24 and the rear inner peripheral surface 29 of the second step engagement groove 26. 1 and is narrower than the distance t between the front inner peripheral surface 28 of the inclined guide surface 22 and the rear inner peripheral surface 31 of the second stage engaging groove 26. A configuration in which the front rod 14 or the rear rod 15 is always engaged with the step engagement groove 24 can be easily realized.
A configuration in which the interval between the front rod 14 and the rear rod 15 of the striker 11 is made wider than the interval between the first-stage engagement groove 24 and the second-stage engagement groove 26 and only the front rod 14 is engaged. Then, the striker 11 becomes larger and becomes heavier to ensure the strength of the striker 11.

Further, when the front rod 14 and the rear rod 15 are respectively engaged with the first-stage engagement groove 24 and the second-stage engagement groove 26, high dimensional accuracy and mounting accuracy are required, and manufacturing is performed. Is troublesome.
In the present invention, the gap between the front rod 14 and the rear rod 15 is reduced, and the front rod 14 and the rear rod 15 are engaged with the first-stage engagement groove 24 so that there is no backlash. In addition, the front rod 14 is fitted with play in the second stage engaging groove 26 to absorb dimensional errors and mounting errors.
The release member 36 that contacts the engagement body 35 of the engagement member 20 is formed with a non-action cam surface 48 following the engagement surface 37, and the non-action cam surface 48 contacts the engagement body 35. since the formed surface shape to reduce the upward rotation amount of polymer 35 (engaging member 20), from a predetermined position of the operation member 42 operated, the infrasound of open- member 36 against the engaging member 35 Thus, the amount of upward rotation of the engagement body 35 is reduced, and the operation system such as the operation transmission member 41 and the operation member 42 is prevented from being damaged.

In other words, the engagement surface 37 of the opening member 36 is rotated by a predetermined amount by the gap 38 and then comes into contact with the engagement body 35. When the contact is made, the engagement surface 37 causes the engagement body 35 to center on the engagement member mounting shaft 21. When the front inner peripheral surface 28 of the engagement member 20 passes the striker 11 (the front rod 14 or the rear rod 15), the engagement body 35 is moved from the engagement surface 37 to the non-acting cam. It moves to the surface 48 (FIGS. 10 to 11).
Since the non-acting cam surface 48 is formed in a surface shape that reduces the upward rotation amount of the engagement body 35 (engagement member 20), even if the opening member 36 is further rotated upward by the operation member 42, the engagement cam surface 48 is engaged. The upward movement direction of the combined body 35 is changed from the initial direction of FIG.

Therefore, the opening member 36 reduces the amount of upward rotation of the engagement body 35 (engagement member 20) by the non-operation cam surface 48, and an excessive operation force by the operation member 42 is applied to the engagement body 35 by the non-operation cam surface. 48 is moved to escape and the breakage and deformation of the operation member 42 and the operation transmission member 41 are prevented.
Further, since the non-operating cam surface 48 has a surface shape that reduces the amount of upward rotation of the engaging body 35, the non-operating cam surface 48 acts to receive the downward rotation of the engaging member 20. When it moves to the latch position by the elasticity of, the engagement body 35 comes into contact with the engagement surface 37 from the non-acting cam surface 48 and returns to the original position.
Further, the outer periphery of the opening member 36 following the non-working cam surface 48 is formed on the retreating surface 49, and the non-working cam surface 48 and the retreating surface 49 are formed even when the opening member 36 rotates the engaging member 20 upward. Since the striker entry groove 12 is arranged so as to be positioned above the upper edge of the striker entry groove 12, the vertical width of the striker entry groove 12 is widened so that the striker 11 can enter easily and smoothly.

The spring 55 that urges the engaging member 20 to the latch position passes the coil portion 56 through the engaging member mounting shaft 21 and first locks one end 57 of the spring 55 in the mounting groove 58 of the engaging member 20. .
In this state, the engaging member 20 is attached to the cover 40.
Next, the other end 59 of the spring 55 is engaged with an engagement protrusion 60 provided on the cover 40.
Since the engaging protrusion 60 is provided above the axis of the engaging member mounting shaft 21 and the cover 40 below the engaging protrusion 60 is formed with a notch 62, the rear side of the engaging member mounting shaft 21 is provided. In addition, it is possible to secure a sufficiently large space for engaging the other end 59 around the engagement protrusion 60, thereby facilitating work.
Further, since the other end 59 of the spring 55 is engaged with the engaging protrusion 60, the other end 59 can be greatly elastically deformed, and there is also a sufficient space for elastic deformation by the notch 62. Makes locking work easier.

For example, the other end 59 of the spring 55 can be moved from the notch 62 in the axial direction of the engaging member mounting shaft 21 and can be engaged with the engaging protrusion 60, facilitating the locking operation.
Since the rear flange 63 is provided in the body 10 at the portion facing the notch 62, when the body 10 and the cover 40 are combined, the rear flange 63 is located in the notch 62, It abuts on or is close to the base vertical plate portion 61 of the cover 40, and acts to prevent the one end 57 of the spring 55 from coming off.
Therefore, the latch device L is configured by sandwiching the engaging member 20 between the body 1 and the cover 40, and the body 1, the cover 40, and the engaging member 20 are assembled by the engaging member mounting shaft 21. Therefore, assembly is very easy.
Since the peripheral position of the striker entry groove 12 of each of the body 10 and the cover 40 is provided with a peripheral rib 65 improves the rigidity of the body 10 and the cover 40.

That is, since the latch device L has the striker entry groove 12 at the upper and lower intermediate positions of the latch device L, the latch device L is divided vertically by the striker entry groove 12, and the striker entry groove 12 reduces the rigidity of the latch device L. One of the causes is that in the present application, since the peripheral rib 65 is provided at the periphery of each striker entry groove 12 of the body 10 and the cover 40, the point that the rigidity of the latch device L is lowered is reinforced, and the entire latch device L The rigidity of can be improved.

In the body 10, the upper step portion 66 and the lower step portion 67 arranged in parallel in the front and rear are respectively arranged on the upper and lower sides of the striker entry groove 12, so that the striker entry groove of the portion with which the striker 11 is engaged is arranged. 12 can be reinforced by the upper step portion 66 and the lower step portion 67 from the upper and lower sides, and the rigidity of the latch device L is improved.

Since the engagement protrusion 60 that engages the other end 59 of the spring 55 is bent toward the body 10 from the base vertical plate portion 61, the rigidity of the cover 40 in the vicinity of the engagement protrusion 60 is improved.
Further, since the rear flange portion 63 that prevents the one end 57 of the spring 55 from being detached is bent toward the striker entry groove 12, the rigidity of the body 10 in the vicinity of the rear flange portion 63 is improved.
That is, the engaging projection 60 is bent formed on the body 10 side of the base over the scan vertical plate portion 61 of the cover 40, the side flange portion 63 after the body 10 is bent formed on the cover 40 side of the base vertical plate portion 64 Therefore, the rigidity of the latch device L around the engaging member mounting shaft 21 can be improved.

Since the body 10 above the striker entry groove 12 is provided with reinforcing lateral ribs 70 that are long in the moving direction of the striker 11, the rigidity of the body 10 near the striker entry groove 12 is improved.
The body 10 and the cover 40 on the upper side of the striker entry groove 12 are formed with a body side upper bent portion 77 and a cover side upper bent portion 78 that are bent toward the cover 40 and the body 10 side, respectively. in one of the bent portion 77 and the cover-side upper bent portion 78 forms an engagement portion 79, the engaging portion 79 to the other of the body-side upper bent portion 77 and the cover-side upper bent portion 78 is engaged Since the mating engagement hole 80 is formed, the engagement portion 79 is engaged with the engagement hole 80 and overlapped so as to sandwich the engagement member 20 from the left and right to engage the body 1 and the cover 40. The member 20 is assembled in a fixed state by the engaging member mounting shaft 21.

Therefore, since the fastening portion at the time of assembly is one place of the engaging member mounting shaft 21, the assembly is ready.
Further, the engaging portion 79 and the engaging hole 80 prevent the body 10 and the cover 40 from being displaced not only in the left-right direction but also in the up-down direction.
Further, since the engaging portion 79 and the engaging hole 80 are engaged with each other, the rigidity of the body 10 and the cover 40 is improved.
An inner member 83 is provided on the inner surface of the cover 40 on the inlet side of the striker entry groove 12, and the inner member 83 is positioned between the base vertical plate portion 61 of the cover 40 and the side surface of the engaging member 20.

The assembly strength is strengthened, and the assembly work to the back sheet 6 is also used to facilitate the work and improve the efficiency.
Thus, the operation transmission member 41 is composed of two cables, the one side cable 41A connected to the one side operation member 42A and the other side cable 41B connected to the other side operation member 42B. The member 42A and the other side operation member 42B can be operated independently by the one side cable 41A and the other side cable 41B.

For this reason, the one-side operation member 42A and the other-side operation member 42B are provided at positions that are sufficiently separated from each other. For example, the one-side operation member 42A is provided in the vicinity of the driver seat, and the other-side operation member 42B is provided on the back seat 6. Then, the operation can be performed at each position, and the operability can be improved.
Both the one side cable 41A and the other side cable 41B are formed by inserting the inner cable 101 into the outer tube 100, and one end of the outer tube 100 is fixed at a predetermined position in the vicinity of the one side operation member 42A and the other side operation member 42B. Since one end of the inner cable 101 is connected to the one-side operation member 42A and the other-side operation member 42B, when one of the one-side operation member 42A and the other-side operation member 42B is operated, two inner cables One of the members 101 is pulled to operate the operation transmitting means (opening member) 36.

Since the other end of the outer tube 100 of the one side cable 41A and the other side cable 41B is fixedly attached to the outer locking portion 103 provided at a predetermined position of the device L, the flexible outer tube 100 is arranged. The separated one side operation member 42A and the other side operation member 42B are connected to the operation transmission means 36 of the apparatus L.
A tip engaging portion 104 is provided at each end of the inner cable 101 of the one side cable 41A and the other side cable 41B, and each tip engaging portion 104 of the one side cable 41A and the other side cable 41B is an operation transmitting means. Since one of the one-side operation member 42A and the other-side operation member 42B is operated, one of the two inner cables 101 is pulled to transmit the operation. The tip engaging portion 104 engaged with the means 36 operates the operation transmitting means 36.

In this case, the cable locking portion 105 and the distal end engaging portion 104 are operated by either one of the one side operation member 42A and the other side operation member 42B, and the corresponding one side cable 41A and the other side cable 41B. Since any one of the front end engaging portions 104 engages with the cable locking portion 105 to rotate the operation transmitting means 36, one of the other one of the non-operated one side operation member 42A and the other side operation member 42B.

Operation transmitting means 36 for become disengaged and it rotates.

The cable locking portion 105 has an engagement groove 112 communicating with the one-side insertion hole 110 and the other-side insertion hole 111, and a fitting hole that can communicate with the engagement groove 112 and fit the tip engagement portion 104. 113, the respective front end engaging portions 104 of the one side cable 41A and the other side cable 41B are fitted into the engaging grooves 112 from the fitting holes 113, and the respective inner cables 101 are fitted into the one side insertion holes 110. And it is made to project from the other side insertion hole 111.
The cable latching portion 105 bends the engagement plate portion 116 at approximately 90 degrees at the distal end of the base plate portion 115, and provides the engagement plate portion 116 with a counter plate portion 117 substantially parallel to the base plate portion 115. The one-side insertion hole 110 and the other-side insertion hole 111 are formed in the portion 116, and the engagement groove 112 communicating with the one-side insertion hole 110 and the other-side insertion hole 111 and the engagement are formed in the opposing plate portion 117. Since there is provided a fitting hole 113 that communicates with the groove 112 and into which the tip engaging portion 104 can be fitted, the tip engaging portion 104 is fitted from the lateral direction of the fitting hole 113 and the inner cable 101 is fitted. Is passed from the engagement groove 112 to the one-side insertion hole 110 or the other-side insertion hole 111.

In the embodiment, since the engagement groove 112 of the one side insertion hole 110 and the engagement groove 112 of the other side insertion hole 111 are communicated so as to cross downward, the distal end engagement portion 104 of one inner cable 101 is The fitting hole 113 is inserted into the one side insertion hole 110 through the left engagement groove 112 in FIG. 25, and the tip engagement portion 104 of the other inner cable 101 is inserted into the right engagement groove 112 from the fitting hole 113 in FIG. Through the other side insertion hole 111.
Since the outer locking portion 103 is provided at a predetermined position of the device L in the tangential direction with respect to the rotation direction of the engagement plate portion 116 of the cable locking portion 105, the inner cable 101 is connected to the outer locking portion 103 and the cable engagement. It is pulled without crossing between the stop portions 105.
Therefore, the two inner cables 101 are not entangled.

That is, since the outer locking portion 103 is arranged in the tangential direction with respect to the rotation trajectory of the engagement plate portion 116 of the cable locking portion 105, the cable locking portion 105 moves in an arc around the shaft 39. The moving direction of the portion 105 can be brought close to a direction substantially parallel to the moving direction of the inner cable 101, and the occurrence of a situation where the two inner cables 101 are entangled can be prevented.
That is, the outer locking portion 103 is the body 1 or the upper position in the crossing direction with respect to the moving direction of the cable locking portion 105 of the operation transmitting means 36 when the operating member 20 moves from the latched state to the unlatched state. Since the cover 40 is provided, when the one side operation member 42A or the other side operation member 42B is operated, the inner cable 101 is pulled upward, and the engagement plate portion 116 of the cable locking portion 105 is moved by the upward movement of the inner cable 101. The tip engaging portion 104 that is in contact with the lower surface moves upward, and the cable engaging portion 105 rotates the operation transmitting means 36 upward by the upward movement of the tip engaging portion 104.

At this time, since the one side insertion hole 110 and the other side insertion hole 111 are formed in a size that does not allow the tip engagement portion 104 to pass through, the inner cable 101 is rotated in FIG. One side insertion hole 110 and the other side insertion hole 111 allow this even if it is swung to the left or right (note that FIG. 28 shows a pair of tip engagement portions for easy understanding of the movement state of the cable locking portion 105. 104 is in contact with the lower surface of the engagement plate portion 116, but does not indicate an actual state.)
Therefore, the inner cable 101 of the non-operating tip engagement portion 104 does not move up and down with respect to the one side insertion hole 110 or the other side insertion hole 111 of the cable locking portion 105, and the tip engagement portion 104 is not engaged. Maintained.

Further, since the base plate portion 115 and the counter plate portion 117 of the cable locking portion 105 are provided at a predetermined interval on the left and right, the tip engagement portion 104 that is in contact with the lower surface of the engagement plate portion 116 is The contact of the cable locking portion 105 that rotates upward to the non-operating tip engaging portion 104 in the non-engaging state that remains in position is prevented.
Further, since the main body 123 of the operation transmitting means 36 is formed to a thickness that does not interfere with the tip engaging portion 104 that moves to the side opposite to the cable locking portion 105 from the engaging plate portion 116, When the main body 123 is rotated upward by an unlatching operation, the tip engaging portion 104 that remains unoperated avoids the main body 123, and the main body 123 is rotated upward without moving the tip engaging portion 104. .

Therefore, the operation transmission means 36 can be rotated upward even at a position where the tip engaging portion 104 that is not operated and the main body 123 of the operation transmission means 36 overlap each other in a side view, and the inner cable 101 is pulled. The amount of operation to be performed can be increased, and the operational feeling of the operator can be improved.
That is, if the operator does not have a certain amount of operation of the one-side operation member 42A or the other-side operation member 42B, the operator does not feel the completion of the operation and inevitably tends to pull the inner cable 101 excessively. When secured enough stroke that can lead the, giving satisfaction to the operator's operation, it is to improve the operational feeling.

Thus, the operation mechanism of the device of the operation transmission member 41 can be used (applied) to various devices. In the present application, the device L is provided between the back sheet 6 of the seat 1 and the fixing portion 3. In addition, since the latch device L that holds the dorsal seat 6 in a predetermined position is used, the operation can be performed by the one side operation member 42A that is separated from the dorsal seat 6, and the operability and workability are improved.
Further, since the operation transmitting member 41 may be a cable and the front end engaging portion 104 may be engaged with the cable locking portion 105, the size of the cable locking portion 105 can be reduced, and the entire apparatus L can be reduced in size. .
The cable locking portion 105 is formed by bending a metal plate member, and the one side insertion hole 110 to the fitting hole 113 are formed in the cable locking portion 105. The cable locking portion 105 is connected to the operation transmission means 36 of the resin member. Since it can be integrally formed by so-called insert molding or the like so as to be embedded in the main body 123, manufacturing is easy and inexpensive.
