Operating member, and method of manufacturing operating portion of operating member

An operating member comprising:

• a body portion;
• an operating portion connected to the body portion;
• an engaging portion arranged in the body portion;
• an engaged portion arranged in the operating portion, and engaged with the engaging portion to connect the body portion and the operating portion;
• a piece portion arranged on a back surface portion of the operating portion and protruding toward the body portion;
• a piece-portion hole arranged in the body portion, into which the piece portion is inserted;
• and
• a protruding portion made of an elastic material, arranged on the piece portion, protruding from a side of the piece portion and press-contacting an edge portion of the piece-portion hole, wherein:
• the operating portion includes an operating-portion main body and an exterior body made of an elastic material and fixed to a front surface portion of the operating-portion main body;
• the engaged portion is arranged on the operating-portion main body;
• the piece portion is arranged on a back surface portion of the operating-portion main body;
• the operating-portion main body includes a through hole arranged in a portion of the operating-portion main body corresponding to a base portion of the piece portion and penetrating from the front surface portion to the back surface portion of the operating-portion main body, and a plug space portion communicating with the through hole and opening to a middle portion of the piece portion;
• and
• a portion of the exterior body is continuously plugged into and fixed to the through hole and the plug space portion, and the portion of the exterior body fixed to the plug space portion provides the protruding portion protruding from the side of the piece portion.

A method of manufacturing an operating portion of an operating member, which includes:

• a body portion;
• an operating portion including an operating-portion main body and an exterior body made of an elastic material and fixed to a front surface portion of the operating-portion main body, and connected to the body portion;
• an engaging portion arranged in the body portion;
• an engaged portion arranged in the operating-portion main body, and engaged with the engaging portion to connect the body portion and the operating portion;
• a piece portion arranged on a back surface portion of the operating-portion main body, and protruding toward the body portion;
• and
• a piece-portion hole arranged in the body portion, into which the piece portion is inserted,
• the operating-portion main body including a through hole arranged in a portion of the operating-portion main body corresponding to a base portion of the piece portion and penetrating from the front surface portion to the back surface portion of the operating-portion main body, and a plug space portion communicating with the through hole and opening to a middle portion of the piece portion,
• a portion of the exterior body being continuously plugged into and fixed to the through hole and the plug space portion,
• the portion of the exterior body fixed to the plug space portion providing a protruding portion protruding from the side of the piece portion,
• the protruding portion press-contacting an edge portion of the piece-portion hole when the piece portion is inserted into the piece-portion hole,
• the method of manufacturing the operating portion of the operating member comprising:
• die molding the operating-portion main body with a first die and a second die, which are separable from each other and provide a cavity for the operating-portion main body;
• separating the second die from the first die;
• die matching the first die, on which the operating-portion main body remains, with a separable third die for providing a cavity for the exterior body using the first die and the operating-portion main body;
• and
• die molding and fixing the exterior body to the operating-portion main body using the first die, the operating-portion main body and the third die.
