<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic circuit for a hydraulic multiple disc clutch, capable of fluid-tightly communicating an oil passage on a relatively rotating clutch drum side with an oil passage on a case side with a simple structure. <P>SOLUTION: The outer periphery of a hollow shaft 106 and a recessed groove 105 are fluid-tightly sealed by a seal ring 109. The inner periphery of the hollow shaft 106 and a torque converter output shaft 26 are fluid-tightly sealed, and an oil chamber 103 is formed in the recessed groove 105. By opening the upstream side of the drum-side oil passage 101 and the downstream side of the case-side oil passage 102 to the oil passage 103, the drum-side oil passage 101 and the case-side oil passage 102 are communicated with each other with a simple structure where the single seal ring 109 is disposed on the outer periphery of the hollow shaft 106. <P>COPYRIGHT: (C)2004,JPO</p> |
