| 摘要 |
The present invention relates to a friction clutch comprising a clutch shaft; a pressure plate being configured to move in a first direction along an axial direction of the clutch shaft to engage the clutch; an operating shaft being configured to move in a second direction by receiving a force in a direction opposite to the first direction when a clutch operator is operated; a sub-clutch having a friction plate, a pressing member, and a torque transmission member, the pressing member and the torque transmission member sandwiching the friction plate therebetween; the friction plate having a first friction face on the other side thereof and a second friction face on the one side thereof, and being coupled to the pressure plate so as to rotate together with the pressure plate; the pressing member being arranged to face the first friction face and being configured to move in the second direction together with the operating shaft and to contact with the first friction face to press the friction plate in the second direction; the torque transmission member being arranged to face the second friction face and being configured to receive the torque of the pressure plate via the friction plate by being pressure-contacted by the friction plate pressed by the pressing member; a slide shaft being coupled to the torque transmission member to rotate together with the torque transmission member and being also coupled to the pressure plate to move along the axial direction together with the pressure plate, the slide shaft being configured to give a force in the second direction to the pressure plate by receiving a torque from the torque transmission member and moving in the second direction; and a transmission member being configured to transmit, to the slide shaft, a portion of the force in the second direction applied to the operating shaft without use of the friction plate when the operating shaft moves in the second direction.
