Zusammenfassung:	An imaging apparatus includes a shutter for controlling object light incident to an image sensor, a holding frame holding the shutter, an annular elastic member for absorbing impact generated when the shutter is driven, a first fastening member engaging with an inner circumferential surface of the annular elastic member, a first body-side support provided to a body of the imaging apparatus, and a first holding-frame-side support provided to the holding frame. On either of the first body-side support and the first holding-frame-side support, a through hole is formed, into which the annular elastic member is press-fitted. A length of an inner circumference of the through hole is greater than a length of an outer circumference of the annular elastic member when the through hole is seen from a direction to which the first fastening member is fastened. Another of the body-side support and the first holding-frame-side support is fastened with the first fastening member.
