Abstract
A rotary device includes a rotatable member having an annular recess and a stationary member rotatably supporting the rotatable member. A circular cap having an outer circumferential edge is fixed to the rotatable member so as to cover an opening of a gap between the rotatable member and the stationary member. A receiving section, which has a shape to receive an adhesive on an outer peripheral portion of the cap, includes a diameter reduction part on the outer circumferential edge. The diameter reduction part has a smaller outer diameter than a maximum outer diameter of the outer circumferential edge. The thickness of the diameter reduction part is larger than or equal to a half of an entire thickness of the outer circumferential edge. An adhesive is applied to the diameter reduction part and the inner peripheral portion.
