PROBLEM TO BE SOLVED: To secure a sufficient engagement strength and a sufficient engagement amount between a lock pawl and an apparatus accessory, even when the plate thickness of a lock member is reduced.SOLUTION: An imaging apparatus includes a mount 6 to which an apparatus accessory 2 is detachably attached and a lock member 18 locking the apparatus accessory 2 attached to the mount 6. The mount 6 includes a guide groove part 6a insertably guiding an engaging projection part formed in the inner circumferential part of the apparatus accessory 2 in an optical axis direction and an engaging groove part engaged with the engaging projection part, when the apparatus accessory 2 is rotation-operated in such a state that the engaging projection part is inserted into the guide groove part 6a. The lock member 18 is formed as a plate-like member and includes a lock pawl 18a formed by performing bending processing to the top end of the lock member 18. The lock pawl 18a is arranged in a gap between the guide groove part 6a and the inner circumferential surface of the apparatus accessory 2 and engaged with the engaging projection part in a circumferential direction, in such a state that the engaging groove part is engaged with the engaging projection part, to lock the apparatus accessory 2 attached to the mount 6. |
