<P>PROBLEM TO BE SOLVED: To provide a cooling structure of a hydraulic clutch release mechanism capable of improving responsiveness, while preventing early deterioration in the hydraulic clutch release mechanism, by improving durability in the hydraulic clutch release mechanism. Ž<P>SOLUTION: An air flowing hole 26 for making air flow between an external part and a space 17 between an outer peripheral part of an input shaft 2 and an inner peripheral part of an inside housing 14, is arranged in one end part of an outside housing 15 installed on a partition wall 5 of a transmission case 4 and a clutch housing 3. A screw part 27 is arranged in the outer peripheral part of the input shaft 2, for sending in air in the space 17 between the outer peripheral part of the input shaft 2 and the inner peripheral part of the inside housing 14 in the axial direction of the input shaft 2. This screw part 27 is formed so as to incline rightward and downward in the axial direction of the input shaft 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
