These

rotation restricting protrusions

70 and 70 come into contact with the restricting portion 32 of each rod 20 when the rotating member 60 rotates more than a predetermined rotation angle, thereby restricting the rotation of the rotating member 60 (see FIG. 5). ).

The rotating member 60 is rotationally biased in the direction of arrow F in FIG. 8 by a biasing spring 75 having one end locked to the base member 40 and the other end locked to the rotating member 60. Thus, the pair of

rods

20, 20 engaged with and connected to the rotating member 60 is urged in a direction to engage with the pair of

lock portions

3, 3. Further, the pair of

rods

20 and 20 are slid in synchronization. When one rod 20 slides, the other rod 20 also slides in conjunction therewith.

Next, the function and effect of the lock device 10 having the above configuration will be described.

That is, as shown in FIG. 4, the bottom surface side of the base portion 23 of the rod 20 is disposed on the bottom surface 41 a side of the base member 40 in a state where the rotating member 60 is rotatably attached to the base member 40. The restriction portion 32 of the rod 20 is disposed on the locking portion 46 side of the base member 40, the rib 33 of the rod 20 is disposed on the elastic piece 50 side of the base member 40, and the base portion 23 of the rod 20 is disposed on the base member 40. From the direction perpendicular to the bottom surface 41 a of the base member 41, it is pushed into the gap between the holding wall portion 48 of the base member 40 and the guide wall portion 63 of the rotating member 60. In this embodiment, as shown in FIG. 4, each rod 20 is pushed in using the marker 27 provided on each rod 20 as a mark.

Then, the locking portion 46 of the standing portion 44 of the base member 40 is pressed and bent by the restriction portion 32 on the one side surface 23a side of the rod 20, and the rib 33 on the other side surface 23b side of the rod 20 causes the base portion to be bent. The elastic piece 50 of the clamping wall 48 of the member 40 is pressed and bent. Then, when the top portion of the locking portion 46 (the portion that protrudes outward most) gets over the restricting portion 32, the locking portion 46 is elastically restored, and its locking surface 46a is locked to the restricting portion 32, and the elastic piece. When the top portion of 50 gets over the rib 33, the elastic piece 50 is elastically restored, and its abutment surface 50a (see FIG. 3) abuts on the rib 33, and the rod 20 is urged toward the rotating member 60. The pair of

rods

20 and 20 are connected to the rotating member 60 in a state where the rack 30 of the rod 20 and the pinion gear 65 of the rotating member 60 are engaged with each other and the rod 20 is prevented from coming off from the bottom surface 41a side of the base member 40. (See FIGS. 5-7).

At this time, in this embodiment, a marker 27 for meshing the rack 30 with the pinion gear 65 of the rotating member 60 at a predetermined position is provided on the surface of the rod 20 opposite to the bottom surface 41a side of the base member 40. Therefore, by attaching the rack 30 of each rod 20 to the pinion gear 65 with the marker 27 as a mark, it is easy to mount the rods 20 so that the distances between the rods 20 and the lock portions 3 facing the rods 20 are equal. become.

In the locking device 10, the side surfaces 23 a and 23 a of the pair of

rods

20 and 20 are engaged with the rack 30 that meshes with the pinion gear 65 of the rotating member 60, and the rack 30 meshes with the pinion gear 65 (see FIG. 6). 5), as shown in FIG. 5, the guide wall 63 of the rotating member 60 can be contacted. Therefore, as shown by the arrow in FIG. 5, even if the rod 20 is pushed toward the rotating member 60 in a state where the rack 30 is engaged with the pinion gear 65, the restricting portion 32 of the rod 20 remains the guide wall portion of the rotating member 60. 63, the pinion gear 65 and the rack 30 are restricted from being excessively close to each other, so that the pinion gear 65 and the rack 30 are prevented from being excessively engaged (the pinion gear 65 and the rack 30 are engaged with each other by a predetermined amount or more). The operation feeling when the rod 20 slides can be maintained well.

Further, in this embodiment, as shown in FIGS. 2 and 6, the restricting portion 32 of the rod 20 has a protrusion that protrudes and extends along the rack 30 at a predetermined height, as shown in FIG. 6. Further, when viewed from the rotational axis direction of the rotating member 60, the tip end in the protruding direction has a shape protruding from the tooth tip 30 a of the rack 30. Therefore, even when the rod 20 is slid, even if the rod 20 is pushed toward the rotating member 60, the restricting portion 32 can be reliably brought into contact with the guide wall portion 63 of the rotating member 60, and the pinion gear 65 and the rack 30 can be contacted. Can be more reliably suppressed, and the slide of the rod 20 can be more stably guided by the protruding restricting portion 32 and the guide wall portion 63.

Furthermore, in this embodiment, as shown in FIGS. 4 and 7, the base member 40 is locked to the restriction portion 32 of the rod 20 to hold the rod 20 against the base member 40. Part 46 is provided. Therefore, the operation of simply assembling the pair of

rods

20, 20 to the rotating member 60 attached to the base member 40 causes the locking portion 46 of the base member 40 to be locked to the restriction portion 32 of the rod 20, and The

rods

20 and 20 can be prevented from coming off, and the rotating member 60 can be rotatably mounted by one base member 40, and the pair of

rods

20 and 20 can also be kept from coming off, and the entire locking device can be held. Can be made into a compact and simple structure.

Further, in this embodiment, as shown in FIGS. 4, 5, and 7, each rod 20 is sandwiched between the guide wall portion 63 and the sandwiching wall portion 48 of the rotating member 60 and the sandwiching wall. Each rod 20 is urged toward the rotating member 60 by the elastic piece 50 formed in the portion 48 (see the arrow in FIG. 7), so that the rack 30 of each rod 20 and the pinion gear 65 of the rotating member 60 are securely engaged. In addition, the generation of abnormal noise due to backlash can be suppressed.
