Abstract
A speed change device includes a power transfer shaft, a tubular shaft member, and a planetary gear mechanism that has a carrier. An in-shaft oil passage is formed in the power transfer shaft. A radially inner portion of the carrier and the tubular shaft member are splined to each other. An inside opening portion of a guide oil passage is formed in a non-spline portion of the radially inner portion. A target race member of a thrust bearing is disposed so as to abut against the carrier. The radially innermost position of the non-spline portion is on the radially outer side of the radially outermost position of a spline engagement portion. An oil receiving portion is formed by the tubular shaft member, the non-spline portion, and the target race member.
