  • Publication number: 20140004743
    Abstract: A connector includes a connecter housing and a case. A housing fixing portion of the case includes a first rib which extends in a circumferential direction of the housing fixing portion. The connector housing includes a second rib which extends in a circumferential direction. An inner circumferential groove which extends in the circumferential direction is formed on an inner circumferential face of the first rib. Vertical protrusions which extend in an inserting direction of the second rib into the inner circumferential groove are formed at a plurality of positions on at least one of vertical side walls defining the inner circumferential groove. Top parts of the vertical protrusions are deformed so as to engage the second rib with the inner circumferential groove when the second rib is inserted into the inner circumferential groove.

  • Patent number: 7244184
    Abstract: A damper mechanism 6 is provided to transmit torque while absorbing and damping torsional vibrations. A small coil spring 45 achieves characteristics of a low rigidity in a small torsion angle region of the torsion characteristics when compressed by rotary members. A coil spring 33 achieves characteristics of a high rigidity in a large torsion angle region of the torsion characteristics when compressed by the rotary members rotating relatively to each other. A frictional resistance generating mechanism 7 generates a frictional resistance while each spring is being compressed. Owing to a rotating-direction space 79, the frictional resistance generating mechanism 7 does not operate in the second stage of the torsion characteristics and also does not in the first stage while a torsion angle is in a predetermined range.

  • Patent number: 7195111
    Abstract: In a clutch device 1, a second flywheel assembly 5 is axially movable within a predetermined range relative to a crankshaft 2, and a flywheel 21 has a friction surface 21a on a side remote from an engine. The damper mechanism 6 elastically couples the flywheel 21 to the crankshaft 2. The clutch disk assembly 9 has a friction facing 54 neighboring the first friction surface 21a. The clutch cover assembly 8 is attached to the flywheel 21, and biases the friction facing 54 toward the first friction surface 21a. The release device 10 applies an axial load directed toward the engine to the clutch cover assembly 8, and thereby releases the load toward the friction facing 54. The relative rotation suppressing mechanism 24 couples the second flywheel assembly 5 to the disk-like member 13 when the clutch cover assembly 8 receives the axial load directed toward the engine.
