Abstract:
To provide a blade driving device capable of preventing the switching of a state when an external force caused by falling, vibration or the like is applied and to provide an imaging apparatus including the blade driving device.SOLUTION: A blade driving device 1 includes a blade member 15 and an operation drive part 16. The blade member 15 includes a cam hole 157 through which the drive pin 165 of the operation drive part 16 is inserted and engagement projection parts 158a and 158b which are formed so as to project from the inside of the cam hole 157. When the drive pin 165 of the operation drive part 16 pushes the end surface of the cam hole 157 of the blade member 15, to drive the blade member 15, the engagement projection parts 158a and 158b of the blade member 15 do not come into contact with the drive pin 165 of the operation drive part 16, but when the end surface of the cam hole 157 of the blade member 15 further pushes the drive pin 165 of the operation drive part 16, the engagement projection parts 158a and 158b of the blade member 15 are engaged with the drive pin 165 of the operation drive part 16, to regulate the drive of the blade member 15.SELECTED DRAWING: Figure 2
