Claims

[Claims for Utility Model Registration] A rail unit consisting of a rail on the vehicle body side and a rail on the seat side that is movably fitted to the rail on the vehicle body side and supports a seat, In a power seat slide device in which a rail on the seat side is moved by power with respect to the rail on the vehicle body side, a screw member is extended in the front-rear direction and rotated on one of the rail on the vehicle body side and the rail on the seat side. an output gear that is rotatable by the power and that is fixed to the screw member is meshed with the input gear, and when the screw member rotates, the other rail moves back and forth relative to the one rail. A nut member attached to the other rail is screwed onto the screw member, and an end portion of the screw member suppresses rotation of the screw member so as to maintain a contact state between the input gear and the output gear. A power seat slide device characterized by being equipped with a rotary control member.
