1. A vehicle seat comprising:
a slide rail that includes a lower rail disposed on a side of a vehicle structure member, and an upper rail disposed on a side of a seat body and supported to be slidable with respect to the lower rail; and a slide lock mechanism that restrains slide movement of the upper rail with respect to the lower rail at a selected position, wherein: the slide lock mechanism includes a lock member that restrains the slide movement of the upper rail at the selected position to achieve a slide lock state, and an operating member that transmits, to the lock member, a canceling operating force for canceling the slide lock state achieved by the lock member; the lock member includes a first urging member that elastically applies an urging force to maintain the slide lock state achieved by the lock member; the operating member includes a second urging member that applies an urging force toward an initial position at which the operating member is located before an operation of the operating member is started; the urging force of the first urging member is set to be larger than the urging force of the second urging member; the operating member is moved from the initial position to an operation position such that the canceling operating force is applied against the urging force of the first urging member and the urging force of the second urging member; when the operating member is located at the operation position, the slide lock state achieved by the lock member is canceled; a clearance is set in a region from the initial position to the operation position; the operating member includes an input operating member to which the canceling operating force is input, and an output operating member that outputs the canceling operating force; the second urging member is provided between the input operating member and the output operating member such that the input operating member and the output operating member are connected to be movable relative to each other; the clearance is provided between the input operating member and the output operating member; the initial position is set by maintaining the clearance between the input operating member and the output operating member using the urging force of the second urging member; and the second urging member includes a first support portion that applies an urging force to the input operating member to support the input operating member, a second support portion that applies an urging force to the output operating member to support the output operating member, and a first engagement portion that is engaged with the upper rail. |
