Abstract
A clutch mechanism used in a system in which first and second driven members are driven using one driving source. The mechanism includes a driving member, a driving side engaging member, an idler side engaging member, an urging unit, a releasing member provided with a cam surface configured to cause the driving side engaging member to move axially, and to perform engagement or release of the driving side engaging member with or from the idler side engaging member, and a cam member provided with a cam surface configured to engage with the cam surface of the releasing member. In at least one of the releasing member and the cam member, at least a portion where collision occurs when the releasing member has moved in an axial direction to approach the cam member, is formed of an elastic member.
