Claims

[Scope of utility model registration request]

a fixed plate fixed on the bed; an end plate arranged on the bed to face the fixed plate and movable in a direction toward or away from the fixed plate;
Four tie bars having both ends fixed to the fixed plate and the end plate and having male threads of a ball screw mechanism on the outer periphery, and four nut members each having a female thread of a ball screw mechanism that engages with the male threads of the four tie bars. A movable plate that is held rotatably while being restrained in the axial direction, and a movable plate that is installed on the movable plate,
