Guide device

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.
