Further, in the latch 17, the free end of the engaging portion 17b is formed approximately perpendicularly to the direction in which the latch 17 enters the locking hole 7 (the left-right direction in FIG. 1). A short bent portion 17c is formed by bending the latch 17 at a right angle toward the center of rotation (upper side in FIG. 1), and the dimensions of each portion are the same as those of the operating portion 13a.
When the latch 17 rotates together with the operating rod 13 by the operation, the bent portion 17c is designed so that it can easily pass through the locking hole 7, and when engaged, the latch 17 is
In the figure, the upper end 17d of the bent portion 17c is the locking hole 7.
It is located slightly above the upper edge 7a of.

上を図ることができる。 The device of the present invention has the same function as the conventional device, and is designed to lock the seat, but in this locked state, the device receives a severe impact, such as when the car collides with an obstacle in front of the vehicle. in case of,
An impact force acts on the sliding frame 3 together with the seat in a direction in which the lock plate 5 on the vehicle body side is horizontally forward or the rear side lifts up using the front side as a fulcrum, and the lock plate 5, bracket 11, or latch 17 is twisted. deform by However, at this time, the bent portion 17c bent upward at the tip of the latch 17 gets caught on the upper edge 7a of the locking hole 7, and the lock plate 5 and the latch 1
7 becomes difficult to disengage. This effect of making the engagement difficult to disengage does not require increasing the thickness of each member such as the latch 17 that makes up the locking mechanism, and can be achieved by a simple process of forming the bent portion 17c. In this embodiment, it is possible to suppress an increase in weight and improve the locking effect at a low cost.
