<p><P>PROBLEM TO BE SOLVED: To provide a multiple disk clutch for a transmission capable of securing power transmission force between a rotary shaft and a clutch drum and support stiffness of the clutch drum and of expecting good reliability. <P>SOLUTION: In a multiple disk clutch structure, a shaft part 26 of which outer circumference surface 26a is rotatably and slidingly contacted and supported by an inner circumference surface 3a of a bearing part opening to a transmission case is formed on the clutch drum 2 of the multiple disk clutch 21, and a hydraulic pressure supply hole 42 bored on a transmission case 1 having a working fluid supply route 41 supplying working fluid to a hydraulic pressure chamber 27 from a hydraulic pressure supply source open a delivery port 42a on an inner circumference surface 3a and a hydraulic pressure supply hole 43 bored on the clutch drum 22 having a supply port 43a communicate to the delivery port 42a and the hydraulic pressure chamber 27 communicate to the delivery port 43b are provided. Since the clutch drum 22 rotatably and slidingly contacts the transmission case 1, support stiffness of the clutch drum 22 is improved. Since sufficient effective length of a spline engagement part is secured, power transmission capacity between the clutch drum 22 and the input shaft 11 are secured. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
