<P>PROBLEM TO BE SOLVED: To simply realize the connection without a looseness between an inner shaft and an outer shaft fitted inside and outside, and to effectively prevent a defect resulting from the looseness from occurring for the long time. <P>SOLUTION: The inner shaft 3a having a circular cross-section and the outer shaft 3b are fitted inside and outside. Splines 30, 31 arranged in the fitting peripheral direction are engaged to connect. A retaining hole 33 bored in the periphery of the outer shaft 3b is formed to insert a ball 34 in the retaining hole 33. At the projection of the ball 34 outside the outer shaft 3b, a ring spring 5 wound around the periphery of the outer shaft 3b is elastically brought into contact with the projection of the ball 34 outside the retaining hole 33, and ball 34 is pressed down against the spline 31 of the periphery of the inner shaft 3a to prevent the looseness between the inner shaft 3a and the outer shaft 3b. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
