PROBLEM TO BE SOLVED: To provide a blade driving device advantageous for reduction in thickness and an imaging apparatus.SOLUTION: The blade driving device includes a blade 105 which enters and comes out of a light passing route, a driving ring 103 which drives the blade 105, and holding substrates (102 and 106) which rotatably hold the driving ring 103. The driving ring 103 is formed of an ultra-slim sheet-like member including an engagement part engaged with the blade 105. The driving ring 103 may be formed of the ultra-slim sheet-like member having a spring property or may be formed of the ultra-slim sheet-like member having a surface layer which is a slidability improvement layer on at least one surface of a sheet base material.SELECTED DRAWING: Figure 1 |
