Abstract
A portion of the target guide plate interposed between the rolling surface of each ball and an inner surface of the sub-concave groove is supported at the other radial surface opposite to the rolling surface of each ball by the inner surface of the sub-concave groove at a state where one radial surface facing towards the rolling surface of each ball is pressed by the rolling surface of each ball and is thus curved along the rolling surface of each ball.
