ABSTRACT:
An elastic shaft coupling comprises a tubular housing having a first inner peripheral surface portion and a second inner peripheral surface portion, a shaft member extending into the tubular housing, an elastic member disposed between the tubular housing and the shaft member, and a displacement preventing portion for preventing excessive relative rotational displacement between the tubular housing and the shaft member. The shaft member has a terminal end disposed in the tubular housing, a first outer peripheral surface portion, and a second outer peripheral surface portion disposed at the terminal end. The elastic member is connected to the first inner peripheral surface portion of the tubular housing and the first outer peripheral surface portion of the shaft member. The displacement preventing portion is disposed between the second inner peripheral surface portion of the tubular housing and the second outer peripheral surface portion of the shaft member.
