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.
Claims8
A stay comprising:
- a first member;
- a second member connected to the first member so as to be capable of rotating around a rotation axis in two opposing directions relatively;
- a disk joined to the first member through a friction plate;
- and
- a cam base capable of rotating around the rotation axis in an integrated manner with the second member, and capable of moving in a direction of the rotation axis through relative rotation of the second member with respect to the first member;
- one of the second member and the cam base further comprising a convex part protruding to the other of the second member and the cam base;
- and
- the other of the second member and the cam base further comprising a concave part which fits with the convex part;
- wherein, when the second member rotates relative to the first member in one direction, the convex part fits with the concave part deeper, the cam base moves away from the 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;
- and
- when the second member rotates relatively to the first member in the other direction, an inclined surface of the convex part and an inclined surface of the concave part come into contact, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and the disk rotate relative to the first member with resistance force.
A stay comprising:
- a first member;
- a second member connected to the first member so as to be capable of rotating around a rotation axis in two opposing directions relatively;
- a disk joined to the first member through frictional force;
- and
- a cam base capable of rotating around the rotation axis in an integrated manner with the second member, and capable of moving in a direction of the rotation axis through relative rotation of the second member with respect to the first member;
- a position retention means between the disk and the cam base for allowing the cam base to move in the direction of the rotation axis with respect to the disk, and for temporarily retaining a position of the cam base in the direction of the rotation axis;
- wherein, when the second member rotates relative to the first member in one direction, the cam base moves away from the 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;
- and
- when the second member rotates relatively to the first member in the other direction, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and the disk rotate relative to the first member with resistance force.
