Rotation output device

A rotation output device, comprising:

• a rotation input body configured to input a rotation driving force;
• a rotation output body located coaxially with the rotation input body and configured to receive a driving force from the rotation input body with a predetermined play angle and to output a rotation force;
• a fixing member provided around an outer circumferential surface of the rotation output body and restricted from rotating;
• a guide holding plate fixed to the rotation output body and configured to rotate integrally with the rotation output body;
• a click spring comprising a first elastic spring arm, a second elastic spring arm, and a central plate, wherein the click spring is fixed to the rotation output body and configured to rotate the guide holding plate with respect to the rotation input body;
• a movement locking plate that is held by the guide holding plate, wherein the movement locking plate is configured to be urged radially outward and to fixedly engage the fixing member;
• a lock operation groove provided in the guide holding plate and configured to release the movement locking plate radially outward to fixedly engage the movement locking plate with the fixing member;
• and
• a release operation groove provided in the rotation input body and configured to guide the movement locking plate radially inward and to release the movement locking plate from the fixed engagement with the fixing member by the rotation of the rotation input body;
• wherein the relative rotation means is configured to relatively rotate the guide holding plate upon stoppage of the rotation driving of the rotation input body.

A rotation output device, comprising:

• a rotation input body comprising a circular recessed portion and engagement grooves on a circumferential surface of the circular recessed portion, wherein the rotation input body is configured to input a rotation driving force;
• a rotation output body located coaxially with the rotation input body and configured to receive a driving force from the rotation input body with a predetermined play angle and to output a rotation force;
• a fixing member provided around an outer circumferential surface of the rotation output body and restricted from rotating;
• a spring plate provided in the circular recessed portion of the rotation input body and comprising a first and a second elastic spring arm, wherein the first and second elastic spring arms are configured to engage the engagement grooves and to rotate the spring plate with respect to the rotation input body upon stoppage of the rotation input body;
• a movement locking plate provided within an inner circumferential surface of the fixing member and comprising a plurality of teeth and a coil spring;
• wherein the coil spring is configured to expand the movement locking plate radially outward and fixedly engage the plurality of teeth to the fixing member upon rotation of the spring plate when the rotation input body stops rotating;
• and
• wherein the plurality of teeth are configured to disengage the fixing member when the rotation input body rotates.
