Claims

[Scope of Claim for Utility Model Registration] 1. 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 the seat, and has both rails. In the power seat slide device, a rack member is fixed to the one rail in the longitudinal direction, a housing of the drive unit is attached to the other rail, and the housing is provided with a drive unit that moves the drive unit relatively. A pinion is secured to a drive shaft which is pivotably supported, the pinion is engaged with rack teeth of the rack member, and has a stop portion in sliding contact with or in close proximity to the rear surface of the rack member opposite to the rack teeth. A retaining member is provided which is pivotally connected to the drive shaft of the pinion, and when fixing the housing, a mounting bolt is inserted into a mounting hole having play in a direction perpendicular to the longitudinal direction of the housing, and the rack member and the rail are connected to each other. An elastic member is interposed between the housing and the other rail to allow movement of the housing in the direction of play in order to absorb errors in parallelism, and the elastic member presses the housing at a resilient point to mount the housing. A power seat slide device characterized in that a bolt is fastened to the other rail. 2. A drive unit that has 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, and that moves both rails relatively. In the power seat slide device, a rack member is fixed to the one rail in the longitudinal direction, a housing of the drive unit is attached to the other rail, and the drive unit is rotatably supported by the housing. A pinion is fixed to the shaft, the pinion is meshed with the rack teeth of the rack member, and a stop portion is in sliding contact with or close to the back surface of the rack member opposite to the rack teeth, and the drive shaft of the pinion is provided. a retaining member pivotally attached to the rack member; when fixing the rack member, a mounting hole having play in a direction perpendicular to the longitudinal direction is bored at the end thereof, and a mounting shaft member is inserted into the mounting hole; In order to absorb errors in parallelism between the rack member and the rail, an elastic member is interposed between the head of the mounting shaft member and the one rail to allow movement of the rack member in the play direction; A power seat slide device characterized in that the mounting shaft member is fixed to the one rail by elastically pressing the rack member with an elastic member.
