Abstract:
A barrel includes a through-hole through which an interlocking lever passes, the interlocking lever provided on a barrier drive member to receive a rotational force. The barrier drive member includes a flange portion in a circumferential direction. The flange portion is positioned at the same phase as the interlocking lever and covers the through-hole from an optical axis direction during a rotation of the barrier blades from an open state to a closed state.
