<P>PROBLEM TO BE SOLVED: To easily secure a seat surface for a pushing pin, on an end surface of a planetary carrier, without changing diameter sizes of an inner and outer splines of the planetary carrier. <P>SOLUTION: The planetary carrier 100 includes: a nearly cylindrical cylinder 130 in which inner and outer splines 131 and 132 are formed; the inner spline 131 formed of one end surface 136 of the cylinder 130; and protrusions 133 formed consecutively from spline teeth of the outer spline 132 from the outer splines 132 through to the one end surface 136 of the cylinder 130. The tooth width 1331 of the protrusions 133 and the tooth bottom diameter 1332 is preferably reduced toward the one end surface 136 side by a die cutting gradient. <P>COPYRIGHT: (C)2012,JPO&INPIT |
