Abstract
A guide apparatus includes a track member, a movable member having a first rolling surface that forms a load rolling passage together with a rolling surface of the track member, and a damper provided on a first surface. The first surface is at least a portion of the surface of the movable member opposed to the track member excluding the first rolling surface. The damper includes a plate member disposed in such a way as to cover the first area and a reservoir space formed between one surface of the plate member and the first area. The reservoir space contains a damping medium and allows the plate member to displace relative to the first area. The damper is provided on the movable member in such a way that the other surface of the plate member slides on at least a portion of the surface of the track member opposed to the movable member.
