摘要： PROBLEM TO BE SOLVED: To provide a ball screw making a seal hardly contact with a screw shaft even if the dislocation of a cutting surface is caused without causing dislocation in the axial direction in the seal even if the seal is deformed as the seal of the ball screw.
SOLUTION: A cutting part 2 is formed in one place in the peripheral direction of a ring of the seal 1. A line (a line forming the cutting surface) 3 visible to the outer peripheral surface of the ring is a V shape (a broken line). This seal 1 can be fitted in the screw shaft by opening the opposed cutting surfaces 21 and 22 of the cutting part 2 by an elastic force. When a load in the axial direction is applied to the seal 1, the dislocation is caused in the direction indicated by an arrow in Fig. 1 (d) and (e), and the seal 1 likely moves to the outside in the radial direction (in a direction separating from the center) even in any direction.
