  • Patent number: 10113344
    Abstract: Provided is a stay which is capable of stabilizing movement of a component part used for transmitting, or not transmitting, the torque of one of a first member and a second member to the other. When a second member rotates relative to a first member in one direction, a cam base moves away from a disk in the direction of the rotation axis, and the second member and the cam base rotate relative to the first member and the disk. When the second member rotates relative to the first member in the opposite direction, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and disk rotate relative to the first member with resistance force.

  • Patent number: 8960387
    Abstract: Provided is a damper position adjusting device capable of adjusting a damping force over a wide adjustment range and facilitating the adjustment work of the position of the damper. The damper position adjusting device has a damper base 38 for storing a plurality of dampers 32 in parallel to each other, each of the dampers 32 having a rod 32a that moves relative to a cylinder 32b; and a damper adjusting shaft 40 which is mounted rotatable in the damper base 38 and has a side wall 44 in contact with ends of the dampers 32 in a moving direction. By rotating the damper adjusting shaft 40, the side wall of the damper adjusting shaft 40 pushes at least one of the dampers 32 out in the moving direction of the rod 32a to change a position of the damper 32 relative to the damper base.

  • Patent number: 8739468
    Abstract: Provided is a door opening and closing device wherein the device width can be made small and wherein the movement of a retraction arm can be stabilized. In a body case (102) which is slender and extends in one direction, there is provided an arm block (121) for a retraction arm (104) which rotates from the open state to the closed state. On one side of the body case (102), there is provided a first slider (134) which, being interlocked with the rotation of the arm block (121), makes linear movements in one direction. In the body case (102), there is provided an arm shaft (105) which serves as the center of rotation of the arm block (121). A second slider (131) which, being interlocked with the rotation of the arm block (121), makes linear movements in one direction, is provided opposite the first slider (134), in such a way as to have the arm shaft (105) held between the first and second sliders (134, 131).
