Abstract:
A joint for integrally rotatably connecting a rotating shaft to an output shaft of an electric motor comprising:a cylindrical first transmission member integrally rotatably mounted on the output shaft; a cylindrical second transmission member enclosing the cylindrical first transmission member via a gap therebetween; a cylindrical elastic body interposed between the cylindrical first transmission member and the cylindrical second transmission member for transmission of the rotation of the cylindrical first transmission member to the cylindrical second transmission member; a cylindrical third transmission member providing integrally rotatable connection of the rotating shaft; and a torque limiter inhibiting relative rotation between the cylindrical second transmission member and the cylindrical third transmission member but permitting the relative rotation therebetween when the rotational resistance of the cylindrical second transmission member or the cylindrical third transmission member exceeds a predetermined value; and flat faces formed at an outer periphery of the cylindrical first transmission member and an inner periphery of the cylindrical second transmission member so as to be in opposed relation with each other and to restrain the cylindrical first transmission member and the cylindrical second transmission member from relatively rotating with respect to each other through a given angle or more.
