<P>PROBLEM TO BE SOLVED: To provide an in-shaft hydraulic supply structure suppressing increase in strength of an oil passage in an retainer, without increasing the length of the shaft. <P>SOLUTION: Output hydraulic pressure of a hydraulic pressure control mechanism outputting the oil pressure from an oil pump chain-driven is supplied to oil passages 1a, 1b in an input shaft through the oil passage in the retainer and an oil passage in a stator shaft. A second oil passage 13 in the stator shaft is disposed to the stator shaft 11, and a second oil passage 32 in the retainer communicating with the second oil passage 13 in the stator shaft is disposed to the retainer 3. The second oil passage 32 in the retainer is constituted of: a bent part 32a communicating with an inner opening part 13a and bent on a stator shaft side; and a straight line part 32b connecting the bent part 32a with the hydraulic control mechanism at the same position in an input shaft direction as the second oil passage 13 in the stator shaft. Each of opening parts 12a, 13a are connected with corresponding oil passages 31, 32 in the retainer, on the same plane where an input shaft is a perpendicular. <P>COPYRIGHT: (C)2011,JPO&INPIT |
