To provide a vehicle seat lock device that has excellent operability, and can be miniaturized while preventing a striker from rattling at a latch position.SOLUTION: A vehicle seat lock device 4 includes a latch 42 and a wedge 43 which are rotatable around a first rotational axis 411. The wedge 43 is slidable in a first direction. A latch body part 421 and a wedge body part 431 are arranged such that at least portions of them overlap each other when viewed in the axial direction. A latch groove 422 and a wedge groove 432 are formed at positions where at least portions of them overlap with each other when viewed in the axial direction. An outer end part 432d in the radial direction of a first wedge support wall 432a is located at a position overlapping with the latch body part 421 when viewed in the axial direction. The wedge 43 slides in the first direction as a striker 5 approaches the first latch position P1, and the first wedge support wall 432a approaches first latch support wall 422a in the circumferential direction.SELECTED DRAWING: Figure 6

    【課題】ストライカがラッチ位置でガタつくことを防止しつつ、操作性に優れ、小型化を図ることができる車両用シートロック装置を提供する。【解決手段】車両用シートロック装置4は、第1回動軸411を軸に回動可能なラッチ42とウェッジ43とを備え、ウェッジ43は第1方向にスライド可能である。ラッチボディ部421とウェッジボディ部431とは、軸方向から見て少なくとも一部が互いに重なる位置に配置され、ラッチ溝422とウェッジ溝432とは、軸方向から見て少なくとも一部が互いに重なる位置に形成されている。第1ウェッジ支持壁432aの径方向の外側端部432dは、軸方向から見てラッチボディ部421と重なる位置に位置し、ウェッジ43は、ストライカ5が第1ラッチ位置P1に近づくほど、第1ウェッジ支持壁432aが周方向において第1ラッチ支持壁422aに近づくように第1方向にスライドする。【選択図】図6
