Abstract

PURPOSE: To ensure a damping force by securing to a guide a pulling bolt which is loosely fitted into a U-shaped elastic body and which can be moved axially by the elasticity of an elastic body provided at the other end, and supporting the guide in such a way that it is rotatable about a semicircular curved surface provided at the guide and used as a fulcrum. CONSTITUTION: A damper 9 and a guide 13 having a gradient surface are opposite to each other across a roller 12, and a semicircular curved surface 28 is provided on the opposite side to the gradient surface of the guide 13 and brought into contact with a U-shaped elastic body 15. A pulling bolt 18 is secured to the curved surface 28 and loosely fitted into a loose fit hole 29 in the elastic body 15. An elastic member 19 is fitted in between a stopper 24 provided at the other end of the pulling bolt 18 and the elastic body 15. Therefore, the damper 9, the roller 12, and the guide 13 are held in such a way as to be movable in the direction of the axis of the pulling bolt 18 and are supported in such a way as to be rotatable using the curved surface 28 as a fulcrum. Therefore, the damper 9 rises while keeping contact and in parallel with guide rails 2, and receives an elastic force to ensure a damping force.
