To provide a rotating operation-type electric part which can transmit the rotation of the operation member to the rotary shaft, and can make the axial size of the rotary shaft small.

This electric part is so constituted that it has a rotation-type electric part member 2, a shaft member 11 arranged in the axial direction of rotation shaft 5 of the rotation-type electric part member 2, an operation member 14 which is provided in the shaft member 11 and facing the rotation- type electric part member 2 in the axial direction and which tilts the shaft member 11 and lets it rotate, and a switch member 15 which operates switching according to the tilting of the shaft member 11. It is also constituted that it has a concave 12 on the end face of the edge 11a of the shaft member 11, that it has a connecting shaft 10 in the rotating shaft 5 which protrudes from the rotation-type electric part member 2 to the operation member 14 along the axial direction, that the tip of the connecting shaft 10 is inserted into the concave 12, that the rotation shaft 5 is rotated via the connecting shaft 10 by the rotation of the shaft member 11, and that the shaft member 11 is tilted by making the tip of the connecting shaft 10 an fulcrum.
