1. A starting device comprising:
a clutch configured to transmit power input from an input member to an input shaft of a transmission device and configured to cut off the power transmission between the input member and the input shaft, wherein the clutch includes a first friction plate arranged to rotate together with the input member, a second friction plate arranged to rotate together with the input shaft of the transmission device, a piston rigidly fixed to the input member so as to rotate together with the input member and move in an axial direction toward the input member to press the first and second friction plates, and an oil-chamber defining member rigidly fixed to the input member so as to rotate together with the input member, the oil-chamber defining member and the piston together defining an engagement-side oil chamber to which hydraulic oil is supplied, wherein a first lubricant passage arranged to supply the hydraulic oil to the first and second friction plates is defined between the input member and the piston, a second lubricant passage communicating with the first lubricant passage is formed in the input member, and a first shaft oil passage communicating with the engagement-side oil chamber and a second shaft oil passage communicating with the second lubricant passage are formed in the input shaft. |
