Rotation member connecting structure and method for manufacturing said structure

A connecting structure of a rotating member, wherein

• the rotating member molded from a resin material is configured to be rotatably connected to a rotating support member molded from a resin material,
• one of the rotating support member and the rotating member includes a main body and a support shaft provided on the main body,
• an other of the rotating support member and the rotating member includes a holding portion that is configured to receive and hold the support shaft,
• the support shaft includes a base portion protruding from the main body, a regulating portion that is configured to regulate axial movement of the support shaft with respect to the holding portion and that is continuously provided at a tip of the base portion in a protrusion direction, and a sliding contact portion that has a circular shape when viewed from an axial direction of the support shaft and that is configured to be in sliding contact with an inner periphery of the holding portion,
• the rotating support member and the rotating member are made of materials that do not join each other when molded from the resin materials,
• the inner periphery of the holding portion has a shape in which a portion in close contact with the sliding contact portion is continuously formed in a circumferential direction, so that the rotating support member and the rotating member are molded in a state of being connected to each other,
• a part of the holding portion is cut off via a slit when viewed from the axial direction of the support shaft,
• the holding portion has a configuration in which a front surface side and a back surface side are open and lateral sides thereof communicate with the slit,
• the inner periphery of the holding portion has a shape in which a central portion thereof has the largest diameter, and
• a width of the base portion is larger than a width of the slit.
