Abstract

A guide device is equipped with a rail having a first surface in contact with a mounting surface, a second surface opposite the first surface, a through hole penetrating between the first surface and the second surface, and a recessed portion that is an opening on a first surface side of the through hole and is formed to be recessed from the first surface toward the second surface, wherein the recessed portion includes a third surface that is a surface orthogonal to the first surface and orthogonal to a width direction of the rail; the recessed portion receives an eccentric part that rotates eccentrically with respect to a reference axis orthogonal to the mounting surface to apply a force to the third surface in the width direction of the rail; and the through hole has a diameter shorter than a length of the recessed portion in the width direction.

Claims (18)

1 . A guide device equipped with a mounting member, a rail, and an eccentric part, wherein the rail is fixed to a mounting surface of the mounting member, the rail comprising:

a first surface in contact with the mounting surface;

a second surface opposite the first surface;

a through hole penetrating between the first surface and the second surface; and

a recessed portion that is an opening of the through hole on a first surface side and is formed to be recessed from the first surface toward the second surface; wherein

the recessed portion includes a third surface that is a surface orthogonal to the first surface and orthogonal to a width direction of the rail;

the recessed portion receives the eccentric part that rotates eccentrically with respect to a reference axis orthogonal to the mounting surface to apply a force to the third surface in the width direction of the rail; and

the through hole has a diameter smaller than a length of the recessed portion in the width direction.

2 . The guide device according to claim 1 , wherein

the eccentric part is a head of an eccentric bolt that rotates about the reference axis.

3 . The guide device according to claim 1 , wherein

the recessed portion is formed up to at least one end of the rail.

4 . The guide device according to claim 1 , wherein

the through hole is formed at a location closer to an end of the rail than a mounting hole that is a hole through which a bolt for fixing the rail to the mounting surface passes.

5 . The guide device according to claim 1 , wherein

the through hole is formed between a plurality of mounting holes that are holes through which bolts for fixing the rail to the mounting surface pass.

6 . The guide device according to claim 1 , wherein

an axial end face of the rail is inclined with respect to an axial direction of the rail.
