Abstract: Provided is a locking device, the fastening strength of which does not vary. A hook is provided with a recess having a first stopper surface and a second stopper surface which extend in the direction of a rotating shaft. A pawl is provided with a projection having a first contact surface capable of contacting the first stopper surface, and a second contact surface capable of contacting the second stopper surface. The provided locking device is one in which the first and second contact surfaces are convexly curving surfaces which project outward toward the first and second stopper surfaces.

Abstract: An outer peripheral portion of a hook in a lock device is formed with a recess, which is formed to extend inwardly from a peripheral surface, and a first face, which is formed at a side of a rotation direction toward the unlock position of the hook than the recess and intersects the rotation direction of the hook, and a pawl is formed with a protrusion, which is detachably engaged with the recess of the hook, and a second face, against which the first face of the hook is capable of abutting.

Abstract: A footrest apparatus for a vehicle seat includes a fixed member fixed to the vehicle seat, a footrest movable between a retracted position and an operating range, and a link mechanism which connects the fixed member and the footrest to each other and moves the footrest between the retracted position and the operating range by extending and contracting. The link mechanism includes a pair of link members which rotate in synchronization with each other, each of which is formed as a plate that is orthogonal to a widthwise direction of the vehicle seat, and a connecting member formed as a plate which extends in the widthwise direction, wherein common edges of the pair of link members are connected to opposite ends of the connecting member in the widthwise direction, respectively.

Abstract: [PROBLEM] An object is to provide a lock device having high locking strength. [SOLUTION] An outer peripheral portion of a hook 57 in a lock device is formed with a recess 57d, which is formed to extend inwardly from a peripheral surface, and a first face 57g, which is formed at a side of a rotation direction toward the unlock position of the hook 57 than the recess 57d and intersects the rotation direction of the hook 57, and a pawl 61 is formed with a protrusion 61a, which is detachably engaged with the recess 57d of the hook 57, and a second face 61c, against which the first face 57g of the hook 57 is capable of abutting.

Abstract: A storable vehicle seat is provided, which can be rotationally moved smoothly and can further be prevented from wobbling in a seating state even though the storable vehicle seat has a structure in which the rotational path of the seat is defined by front and rear links. An elongated support hole 52 and a guide hole 53 are formed in a seat cushion frame 50, a rotational support shaft 30 which is rotatably engaged in the elongated support hole 52 to be relatively movable therein and a guide projection 60 which is engaged in the guide hole 53 to be movable therein are projected from an end of the front link 27, and an extension spring S is installed between the rotational support shaft 30 and a locking projection 56 of the seat cushion frame 50 to bias the rotational support shaft 30 rearwardly.
