1. A rotary electric component comprising:
an operation part that is operated to perform a rotation;
a housing part including an accommodating part that includes a peripheral wall surface, the peripheral wall surface including an irregular part formed thereon;
a rotating body housed in the housing part and connected to the operation part, the rotating body being disposed so as to rotate along the peripheral wall surface in accordance with the rotation of the operation part;
a biasing part that performs biasing toward the peripheral wall surface; and
a rotating piece disposed at the rotating body so as to be brought into contact with the peripheral wall surface by the biasing of the biasing part, wherein the rotating piece rotates while moving along the peripheral wall surface according to the rotation of the rotating body, and the rotating piece includes a recess and a facing surface facing the peripheral wall surface, the recess being for holding a lubricant and formed in the facing surface
wherein the rotating piece has a columnar shape
with an outer peripheral surface facing the peripheral wall surface, and
wherein the recess of the rotating piece is formed in the outer peripheral surface so as to extend obliquely with respect to a rotation direction of the rotating piece.
