Claim 14:
15. A rotation module comprising:
a shaft;
cylindrical housing configured to be capable of performing a rotational motion about the shaft;
a cylindrical cam penetrated by the shaft and accommodated in the cylindrical housing, wherein the cylindrical cam is configured to be capable of performing a linear motion on the shaft;
a guide pin coupled to the cylindrical housing and configured to correspond to a guide groove provided in a cylindrical surface of the cylindrical cam; and
a spring accommodated in the cylindrical housing and configured to elastically support the cylindrical cam,
wherein due to interaction between the guide pin and the guide groove, there is a conversion between the rotational motion of the cylindrical housing and the linear motion of the cylindrical cam.
