<p>PROBLEM TO BE SOLVED: To solve the problem that, when an optical member opening part is provided below an imaging lens optical axis, if a rotation shaft is provided further below the optical member opening part, an entire hood barrier elongates and a size in a radial direction is enlarged, thus resulting in a factor inhibiting an imaging device from being downsized.SOLUTION: In a hood member to be attached in front of an imaging lens of an imaging device, the hood member has a first opening part and second opening part, and the hood member includes a barrier member that protects the imaging lens. The barrier member is capable of performing a turning action around a rotation shaft, and by the turning action, is movable between a first position where the first opening part is covered and a second position where the first opening is opened, and the rotation shaft is arranged between the first position and second position or arranged at a position where the fist position and second position overlap with each other. In the barrier member, an optical path passing part to allow the barrier member at the second position to transmit light to the first opening part and the second opening part is provided.</p> |
