Rotate 80 to the unlocking operation position. Since the left-right direction distance L3 from the front end (rear end) of the operating member 80 moved to the unlocking operation position to the left side surface of the gripping recess 72 is 60 mm or less, the right hand can be obtained by rotating the operating member 80 to the unlocking operation position. The remaining finger of the right hand can be hung on the holding recess 72 while the operation member 80 is held in the unlocking operation position with the thumb of the user.
When the operation member 80 positioned at the initial position is rotated to the unlocking operation position side in this way, the rotation pulley 82 rotates and the operation wire W is pulled, so the left and right lock switching members positioned at the lock allowable position. 84 rotates to the unlocked position side. Then, when the lock switching member 84 is rotated by a predetermined distance to the lock release position side, the pressing piece 86 of the lock switching member 84 that has been separated from the lock claw 62 (the pressed portion 64) until then becomes the pressed portion 64. Contact. When the lock switching member 84 is rotated to the unlock position by rotating the operation member 80 to the unlock operation position, the left and right lock claws 62 are rotated to the unlock position. The portion 61 escapes outward from the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member to be locked 36, and the lock by the lock claw 62 is released (see the phantom line in FIG. 11).

  If the slide board 71 is pulled backward while the operation member 80 is held in the unlocking operation position, the roller 55, the roller 56, and the support roller 49 rotate, so the upper rail 50 and the board unit 70 are moved rearward with respect to the lower rail 30. Can be slid. When the left and right lock claws 62 are positioned on the sides of the member 37 to be locked, when the operation member 80 is released and the operation member 80 is rotated and returned to the initial position, the lock switching member 84 is rotated and returned to the lock allowable position. Therefore, the left and right lock claws 62 are rotated and returned to the lock position, and the engagement protrusion 61 is engaged (locked) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member 37 to be locked. Can be held at an intermediate position (not shown). Further, when the left and right lock claws 62 are positioned on the side of the member 38 to be locked, if the hand is released from the operation member 80 and the operation member 80 is rotated and returned to the initial position, the engagement protrusion 61 of the lock claw 62 is obtained. Engages (locks) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member to be locked 38, so that the slide board 71 can be held at the maximum drawing position (not shown).

  As described above, in the slide deck device 20 of the present embodiment, the cover member 34A is parallel to the lower rail 30, and the inner edges of the pair of lip portions 34A2 are parallel to each other and the extending direction of the lower rail 30 (front-rear direction). It can be mounted in a short time so as to be parallel to.

  Further, when the lock switching member 84 (pressing piece 86) is located at the lock allowable position, the lock switching member 84 (pressing piece 86) is separated from the lock claw 62 (pressed portion 64), and therefore, between the operation of the operation member 80 and the operation of the lock claw 62. There is a predetermined play. Therefore, since the lock claw 62 does not move only when the operation member 80 is slightly moved due to a load or the body of a passenger hitting the operation member 80, the possibility that the lock by the lock claw 62 is unexpectedly released is small.

  Further, when the operation member 80 is rotated to the unlocking operation position when the rear portion of the vehicle 10 is parked on a slope with the rear portion being positioned below the front portion, the slide board 71 is caused to change its own load or the slide board 71. The load of the load placed on the upper surface may unexpectedly try to slide backward. However, in such a case, the operator tries to keep gripping the concave recesses 72 and 73 with the left and right hands in a reflective manner, but the right hand is open in the left and right direction (the left and right of the thumb and little finger). Because the direction interval is considerably wide), it is easy to reflect the thumb away from the operation member 80 in a reflective manner. In addition, when the operator removes the thumb from the operation member 80, the operation member 80 rotates to the initial position, which is a position away from the holding recess 72 as compared to the unlocking operation position. There is almost no possibility of operating the operating member 80 in a reflective manner. Therefore, in such a situation, the lock claw 62 located at the unlock position rotates to the lock position. Therefore, when the lock claw 62 is located at a position corresponding to the member 37 to be locked, the engagement claw of the lock claw 62 The portion 61 automatically engages (locks) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member 37 to be locked. Therefore, in the slide deck device 20 according to the present embodiment, the possibility that the board unit 70 slides at a stretch beyond the intermediate position to the maximum drawing position is extremely small.

If the rail unit 25 is assembled in advance so that the support roller 49 (and the support bracket 47) are in a predetermined position and direction with respect to the rear connection member 43, the support roller 49 is attached by attaching the rail unit 25 to the bottom plate 15. Is in a predetermined position and a predetermined direction with respect to the bottom plate 15. As described above, when the slide deck device 20 is attached to the bottom plate 15, it is not necessary to adjust the position and direction of the support roller 49 with respect to the bottom plate 15, so that the slide deck device 20 can be easily attached to the bottom plate 15. In addition, the two support rollers 49 can surely prevent the bending of both sides of the center portion of the slide board 71, and the slide board 71 can be smoothly slid by the support roller 49.
Moreover, since the load support portion 44 provided on the lower surface of the rear connection member 43 that supports the support roller 49 is in contact with the bottom plate 15, the rear connection can be achieved even when a heavy load is placed on the slide board 71. The central portion of the member 43 is not greatly bent. Therefore, even when a heavy load is placed on the slide board 71, the lower surface of the slide board 71 can be stably supported by the support roller 49.
Further, since it is not necessary to fix the load support portion 44 to the bottom plate 15 with screws or the like, the work of attaching the rail unit 25 to the bottom plate 15 is not complicated.

Moreover, since the rear bracket 27, which is a member for fixing the left and right lower rails 30 to the bottom plate 15, is used as a member for fixing the rear connection member 43 to the lower rail 30, the rear connection member 43 is used. The number of parts can be reduced compared to the case of separately providing the bracket.
Furthermore, when both ends of the rear side connecting member 43 are fixed to the lower rail 30 or a bracket fixed to the lower rail 30 (not contacting the bottom plate 15), this load is applied when a heavy load is placed on the slide board 71. Therefore, the left and right lower rails 30 are deformed, and as a result, the sliding operation of the upper rails 50 may become unsmooth. However, since both ends of the rear connection member 43 are fixed to the rear bracket 27 that contacts the bottom plate 15, the load applied to the slide board 71 is supported by the support roller 49, the rotating shaft 48, the support bracket 47, and the rear connection. It is transmitted to the bottom plate 15 via the member 43 and the rear bracket 27 and is not transmitted to the lower rail 30. Therefore, even when a heavy load is placed on the slide board 71, the sliding operation of the upper rail 50 does not become unsmooth.

  Further, since the gap between the cover member 34A provided on the lower rail 30 and the upper rail 50 is narrow (see FIGS. 5, 6, and 9), the upper surface of the lower rail 30 is raised by pulling the slide board 71 rearward. Even if a passenger drops a small object in a state where it is exposed, the possibility that the object will enter the lower rail 30 through the gap between the cover member 34A and the upper rail 50 is very small. Moreover, even if the object enters the lower rail 30 through the gap between the cover member 34A and the upper rail 50, when the slide board 71 is slid to the storage position (front end position), the roller 55 presses the object forward. When the slide board 71 reaches the storage position, the object is lifted obliquely upward by the tapered surface of the head of the front end stopper member B3 and is discharged from the front end opening of the lower rail 30 to the front of the lower rail 30. The passenger can easily take the object out of the lower rail 30.

The present invention can also be implemented in aspects other than the above embodiment.
For example, instead of the cover member 34A, a cover member 34B shown in FIG. 15 or a cover member 34C shown in FIG. 16 may be used.
The cover member 34B shown in FIG. 15 is made of the same material as the cover member 34A, and includes a pair of attachment portions 34B1, a lip portion 34B2, a thin wall portion 34B4 (fragile connection portion), a corner cut 34B5 and a concave groove 34B6, and a removal portion 34B3. Are provided. However, the corner portion of the attachment portion 34B1 is rounded, and the removal portion 34B3 is wider than the removal portion 34A3. Further, since the corner cut 34B5 is deeper than the corner cut 34A5, the vertical portion and the horizontal portion of the attachment portion 34B1 are easy to rotate relative to each other. Therefore, it is easier to stick the double-sided tape S1 and the double-sided tape S2 to the lower rail 30 than the cover member 34A.
On the other hand, the cover member 34C shown in FIGS. 16 and 17 is also made of the same material as the cover member 34A, and includes a pair of attachment portions 34C1, a lip portion 34C2, a thin portion 34C4 (fragile connection portion), a corner cut 34C5, and a concave groove 34C6. And removal unit 34C3. However, the corners of the mounting portion 34C1 are rounded, and the corner cut 34C5 is deeper than the corner cut 34A5. Further, a low friction member S3, which is a long object made of urethane extending in the front-rear direction, is attached to the lower surfaces of the pair of lip portions 34C2. Therefore, as shown in FIG. 17, even if the left and right side surfaces of the upper rail 50 are in contact with the inner surface of the low friction member S <b> 3, the friction resistance between the low friction member S <b> 3 and the upper rail 50 is small. It can slide smoothly.

Alternatively, the inner edge portions of the lip portions 34A2, 34B2, and 34C2 may be brought into contact with both side surfaces of the upper rail 50, or the low friction member S3 may be attached to the lower surfaces of the lip portion 34A2 and the lip portion 34B2.
Furthermore, you may shape | mold thin part 34A4, 34B4, 34C4 with the same material as another part.
Further, the cover members 34A, 34B, 34C may be attached to the lower rail 30 by fixing means other than the double-sided tapes S1, S2, for example, an adhesive.
Moreover, you may form the weak connection part of a structure different from thin part 34A4, 34B4, 34C4 in cover member 34A, 34B, 34C. Such a weak connection part is realizable by the perforation extended in the front-back direction (The part to form may be a part with the same thickness as a peripheral part, and may be a thin part), for example.

  Furthermore, although the cover member 34A (34B, 34C) is attached to the lower rail 30 of the slide deck device 20, the present invention is applicable to all lower rails that support the slidable upper rail. Therefore, for example, the cover member 34A (34B, 34C) may be applied to a so-called slide seat lower rail.
