<P>PROBLEM TO BE SOLVED: To suppress an outflow of hydraulic oil while promoting a discharge of air when filling a cancel oil chamber of a hydraulic clutch with hydraulic oil, and more suitably secure centrifugal hydraulic pressure in the cancel oil chamber. <P>SOLUTION: An end surface 520 of a sleeve 52 fitted into an inner cylinder portion 303 of a clutch drum 30 comes into contact with an end portion 303d formed at the inner cylinder portion 303. The sleeve 52 comprises: a first passage 521 which is communicated with a relay oil passage 303c communicated with a first cancellation oil chamber 37 formed at the inner cylinder portion 303 of the clutch drum 30, and which is formed at an outer circumference of the sleeve 52 to extend toward the end surface 520 in an axial direction; and a second passage 522 which extends in a radial direction and is recessed more in the axial direction than in the end surface 520 so as to connect the first passage 521 to an inner portion of the sleeve 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
