Claims

[Scope of Utility Model Registration Claim] A rail unit that has a rail on the vehicle body side that is fixed to the installation site and a rail on the seat side that fits into the rail on the vehicle body side so as to be movable back and forth relative to the seat side and supports the seat. In the power seat slide device, the power seat slide device is configured to adjust the longitudinal position of the seat by relatively moving the rail on the vehicle body side and the rail on the seat side in the longitudinal direction using power via a drive section, The part has a gear case in which a worm case part for storing a worm rotated by the power and a worm wheel case part for storing a worm wheel that meshes with the worm are integrally formed in the vertical direction, The worm case part fits into one of the rails on the vehicle body side or the rails on the seat side so that the gear case can be inserted into the space between the side rail and the seat side rail from the front and rear directions. The other rail is formed to have a constant groove-like cross section so that the worm wheel case part can fit thereinto, and the groove wall of the one rail and both sides of the gear case are connected to each other. A fitting groove extending in the front-rear direction is formed on one of the rails, and a protrusion that is fitted into the fitting groove and restrains the gear case from wobbling on a plane orthogonal to the front-rear direction is attached to the groove of the one rail. A power seat slide device, characterized in that it is formed on the other of a wall and both sides of the gear case.
