In a vehicle seat that can rotate a seat body between a position where it faces the front side of a vehicle and a position where it faces a door opening and can move the seat body in the lateral direction of the vehicle, an actuator such as an electric motor is conventionally used in order to release a rotation lock mechanism for rotationally locking the seat body. This resulted in high costs. Further, it was necessary to provide a space for providing the cable or the like. As a result, it was difficult to reduce in size of the vehicle seat. The present invention provides a mechanism that can release the rotation lock mechanism without using an actuator. In the present vehicle seat, a nut ( 73 ) is moved upon rotation of a screw shaft ( 72 ) so that the seat body is moved in the lateral direction of the vehicle. When the nut ( 73 ) is moved by a desired distance, a guide roller ( 69 ) is pushed so that an operation arm ( 66 ) is moved parallel with the guide roller. As a result, a lock plate ( 64 ) is rotated in an unlock direction so that a claw ( 64 a) is disengaged from a striker ( 61 ).
