A lock lever bracket fixed to an upper rail and serving as a lock mechanism for locking the upper rail sliding relative to a lower rail includes shaft support holes which are separated from each other in the slide direction of the upper rail and through which an open rod is inserted. A lock lever includes two bearing portions which are disposed close to both shaft support holes of the lock lever bracket and a rotation transmission groove. The open rod includes a linear shaft portion which extends through each shaft support hole and each bearing portion and a bent portion which engages with the rotation transmission groove of the lock lever and rotates along with the linear shaft portion so as to rotate the lock lever in the unlock direction. The bearing portion of the lock lever is formed as a clip-shaped bearing portion in which a pair of plate-shaped portions is provided separated from each other in the insertion direction of the open rod, bearings are formed by bending the pair of plate-shaped portions in the opposite directions so as to interpose the open rod therebetween, and a gap between the bearings in the radial direction is smaller than a diameter of the open rod. |
