<P>PROBLEM TO BE SOLVED: To provide an industrial vehicle miniaturized transmission device. <P>SOLUTION: The transmission device comprises an input shaft 10 and an output shaft 20 rotatably supported in a case 2, and a clutch device 30 for making a first rotary disc D1 in pressure contact with a second rotary disc D2 rotatable relative to the first rotary disc D1 to transmit power from the input device 10 to the output shaft 20 and for eliminating the pressure contact to cut off the power transmission. The clutch device 30 has thrust members 31, 32, and hydraulic power generating means 15, 35, 36 for thrusting the thrust members 31, 32 to one direction with the clutch operating pressure of pressure oil from a hydraulic pressure source to make the first rotary disc D1 in pressure contact with the second rotary disc D2 and for thrusting the thrust members 31, 32 to the other direction with the clutch cancelling pressure of pressure oil from the hydraulic pressure source to eliminate the pressure contact. <P>COPYRIGHT: (C)2008,JPO&INPIT |
