Abstract
A displacement detection device is for detecting a change amount of relative positions of two parts as an angle displacement amount. The displacement detection device includes a link mechanism configured to connect the two parts, the link mechanism including at least one joint part; and a rotation angle detector connected to one end of the link mechanism. A spring is used as the at least one joint part of the link mechanism.
Claims6
A displacement detection device for detecting a change amount of relative positions of two parts as an angle displacement amount, the displacement detection device comprising:
- a link mechanism configured to connect the two parts, the link mechanism including at least one joint part;
- and
- a rotation angle detector connected to one end of the link mechanism, wherein
- a spring is used as the at least one joint part of the link mechanism,
- the spring is a torsion coil spring,
- the link mechanism includes two of the torsion coil springs,
- the link mechanism includes
- an intermediate connection part configured to connect the two of the torsion coil springs,
- a detector connection part extending from one of the two of the torsion coil springs, and
- a detection object connection part extending from another one of the two of the torsion coil springs, and
- the two of the torsion coil springs are formed by processing a single metal wire.
