Claims

[Scope of utility model registration request]

A linear movement device comprising two parallel first guide shafts and a second guide shaft for guiding a carriage carrying an object to linearly move the object in both directions. at least two first fixed rotating bodies that abut in a horizontal direction and at least two second fixed rotating bodies that abut in a horizontal direction, and are connected to one end of a first support plate biased by a first spring member. Said first
At least one first pressing rotating body is provided that presses the guide shaft from the side opposite to the first fixed rotating body in a direction perpendicular to the guide shaft; a third fixed rotating body is provided on the carriage at an angle of about 45° with respect to the horizontal direction of the second guide shaft;
A second support plate having a slope in the direction is fixed, and a third support plate rotatably supported on the second support plate and a fulcrum is provided, and the third support plate and the second support plate are supported. A second spring member is connected to one end of the fulcrum at a position far away from the fulcrum, and the third support plate is biased by the second spring member at an angle of approximately 45° on the opposite side from the third fixed rotating body. A precision linear movement device comprising at least one second pressing rotating body that presses the second guide shaft from the direction.
