Summary: | PROBLEM TO BE SOLVED: To provide a vehicular seat lock device which can be downsized as compared with a conventional structure.SOLUTION: A seat lock device 20 includes: a base member 30 which has a base groove portion 31 in which a striker 100 can be inserted; a latch 40 which can rotate between a lock position where the latch 40 is attached to the base member 30 and restrains the striker 100 between the latch 40 and the base groove portion 31, and an unlock position releasing the striker 100; and a cam ball 50 which can rotate between a permission position permitting rotations of the latch 40 and a locking position locking the latch 40 at the lock position, and rotates with lock releasing operation. The cam ball 50 has a regulating surface 55 and a cam surface 54 on the same peripheral surface. The regulating surface 55 regulates rotations of the latch 40 in the unlock position direction by making the latch 40 abut on a contacting surface 48. The cam surface 54 abuts on the contacting surface 48 to rotate the latch 40 in the lock position direction and regulates the rotations of the latch 40 in the unlock position direction.SELECTED DRAWING: Figure 2
【課題】従来構造に比べて小型化可能な車両用シートロック装置を提供する。【解決手段】シートロック装置20は、ストライカ100の挿入可能なベース溝部31を有するベース部材30と、ベース部材30に取り付けられてベース溝部31との間でストライカ100を拘束するロック位置とストライカ100を解放するアンロック位置との間で回動可能なラッチ40と、ラッチ40の回動を許容する許容位置とロック位置でラッチ40を係止する係止位置との間で回動可能であってロック解除操作に伴い回動するカムポール50とを備える。カムポール50は規制面55とカム面54とを同一周面上に有する。規制面55は、ラッチ40の接触面48との当接によりラッチ40のアンロック位置方向への回動を規制する。カム面54は、接触面48との当接によりラッチ40をロック位置方向に回動させるとともにラッチ40のアンロック位置方向の回動を規制する。【選択図】図2 |
