<p><P>PROBLEM TO BE SOLVED: To provide a one-way clutch unit capable of being secured to other member simply and certainly and manufacturable with less man-hours at low cost. <P>SOLUTION: In the range from an engagement cam face 7 to a track groove 8 on the inside surface of an inner ring 2, a threaded hole 20, a minor diametric circular hole 24, and a major diametric circular hole 29 are formed in the sequence as named so that the threaded hole 20 and the minor diametric circular hole 24 are in communication and also the minor diametric circular hole 24 and the major diametric circular hole 29 are in communication and that the inside diameter of the major diametric circular hole 29 is greater than that of the threaded hole 20 and also the inside diameter of the threaded hole 20 is greater than that of the small diametric circular hole 24. On the approximately same pitch circle at the bottom of the major diametric circular hole 29, two pin holes 30 are formed having communication with the major diametric circular hole 29 and extending approximately in the axial direction. The engagement cam groove 7 and the track groove 8 are formed at the periphery of the inner ring 2 in such a way that the outside diameter of the engagement cam surface 7 is smaller than that of the track groove 8. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
