PROBLEM TO BE SOLVED: To solve the problem in which a component for preventing a rebound increases in a rebound prevention mechanism to quicken an exposure start, and further a system for preventing the rebound has been complicate.SOLUTION: A mirror holding mechanism according to one embodiment of the present invention is a mirror holding mechanism to be installed in a camera body, and the mirror holding mechanism comprises: a main mirror unit that rotates between a first state obliquely provided in a subject light flux and a second state retreated from the subject light flux; and a sub-mirror unit that interlocks with the main mirror unit to oscillate, is obliquely provided in the subject light flux in the first state, and is retreated from the subject light flux in the second state. In an operation displacing from the first state to the second state, the sub-mirror unit displacing toward a retreat direction is configured to perform a first contact with the main mirror unit at timing when the main mirror unit rebounds at an end to displace in an oblique providing direction. |
