<p>PROBLEM TO BE SOLVED: To reduce wear of a rotary shaft in a pressure oil supplying structure to a clutch drum of a transmission. SOLUTION: This pressure oil supplying structure to a clutch drum 22 of a transmission is structured so that a hydraulic chamber 25 is formed between the clutch drum 22 rotating together with a rotary shaft 5 and a piston 23 and that the oil from an oil passage 17 furnished on the stationary wall 24 around the rotary shaft 5 is led into the hydraulic chamber 25 via a supply hole 22a provided in the clutch drum 22. The oil supply hole 22a is coupled with the oil passage 17 through an oil passage portion 17b which is parallel with the rotary shaft 5.</p> |
