Abstract
An optical device includes a movable member that holds an optical element and is rotatable about a first rotation axis parallel to an optical axis, and a transmission mechanism that transmits a force from an operation portion to the movable member. The movable member is switchable between an inserted state in which the optical element is inserted onto the optical axis and a retracted state in which the optical element is retracted from the optical axis according to an operation of the operation portion, and the transmission mechanism and the first rotation axis do not overlap with each other when switching between the inserted state and the retracted state when viewed from the optical axis direction.

An optical device comprising:
- a movable member configured to hold an optical element and be rotatable about a first rotation axis parallel to an optical axis;
- and
- a transmission mechanism configured to transmit a force from an operation portion to the movable member,
- wherein the movable member is switchable between an inserted state in which the optical element is inserted onto an optical axis and a retracted state in which the optical element is retracted from the optical axis according to an operation of the operation portion, and
- wherein when viewed from the optical axis direction, the transmission mechanism and the first rotation axis do not overlap with each other when switching between the inserted state and the retracted state.
