<p>PURPOSE:To reduce a size of a hydraulic clutch mechanism in the diameter direction by supplying pressure oil to a portion between a fixed plate and a sliding body, slidingly displacing the sliding body relatively to the fixed plate, pressing a fixed end of the sliding body to a friction plate unit which is engaged with the sliding body and a hollow shaft to the side of the fixed plate. CONSTITUTION:A pressure receiving chamber P is formed between a sliding body 9 and a fixed plate 28, while an oil passage 30 formed on a clutch shaft 15 is communicated therewith. In the case that pressure oil is supplied from the oil passage 30, seal rings 37 are arranged respectively between the sliding body 9 and the fixed plate 28, between the fixed plate 28 and the clutch shaft 15, and a seal ring 35 is arranged between a boss 9a of the sliding body 9 and the clutch shaft 15, so as not to cause leakage of the pressure oil from the pressure receiving chamber P. When the pressure oil is supplied to the pressure receiving chamber P, the sliding body 9 is slidingly displaced in an axial direction relatively to the fixed plate 28. A pressing ring 40 serving as a fixed end of the sliding body 9 presses a frictional plate mechanism 27 to the side of the fixed plate 28, for transmitting power of a hollow shaft 29 to the clutch shaft 15.</p> |
