PROBLEM TO BE SOLVED: To position a seat on a floor without using a specific member by providing a structure where a displacement of a seat position with respect to a floor portion is restricted completely when the seat is latched with respective strikers with front/back locking means. SOLUTION: A seat 2 is swung about an axial line of a striker 16 and when a lock unit 12 is pushed into a striker 14, the striker 14 is relatively fitted into a receiving groove. When the lock unit 12 is further pushed in, the striker 14 relatively guides the receiving groove and latches a latch 26 at an appropriate latching position. In this case, since the latch 26 is free to move in the axial direction of the striker 14, that is in the vehicle longitudinal direction, predetermined undercuts D, E are provided at the front and back of the latch 26 respectively. When the front and back strikers 14, 16 are latched with the latches 26, 36 respectively, the seat 2 can be positioned securely on a floor panel 10.
