A lens barrel includes a frame body, a support frame, and a refracting lens frame. The support frame is configured to be supported by the frame body and move within a plane perpendicular to the optical axis with respect to the frame body. The refracting lens frame includes a lens support portion and is configured to retract around a retraction shaft. The frame body includes an opening portion. The opening portion is configured to open outward with respect to the optical axis. The opening portion is configured to house part of the lens support portion during a transition period between an imaging enabled state and a housed state. The support frame includes a light blocking portion. The light blocking portion is provided in front of part of the opening portion in an optical axis direction in order to block light rays.

1. A lens barrel, comprising: a frame body;a support frame configured to be supported by the frame body and move within a plane perpendicular to the optical axis with respect to the frame body; anda retracting lens frame including a lens support portion and configured to retract around a retraction shaft, the lens support portion configured to support a lens, the retraction shaft being substantially parallel to the optical axis with respect to the support frame,the frame body includes an opening portion, the opening portion configured to open outward outwardly in a radial direction with respect to the optical axis and house part of the lens support portion during a transition period between an imaging enabled state and a housed state,the support frame including a light blocking portion, the light blocking portion provided on an object side of part of the opening portion in an optical axis direction in order to block light rays that pass the opening portion. 2. The lens barrel according to claim 1, wherein the light blocking portion is configured to overlap the lens support portion when viewed in the optical axis direction, during the transition period between an imaging enabled state and a housed state. 3. The lens barrel according to claim 2, wherein the light blocking portion is a first light blocking portion, andthe frame body includes a second light blocking portion provided on the opening portion in order to block light rays which pass the opening portion and do not pass the lens included in the retracting lens frame. 4. The lens barrel according to claim 3, wherein the lens support portion includes a cut-out portion provided on an outside in a radial direction with respect to the optical axis direction during a transition period between the imaging enabled state and the housed state, andthe cut-out portion is disposed opposite the second light blocking portion during the transition period between the imaging enabled state and the housed state. 5. The lens barrel according to claim 1, wherein the frame body includes a shutter unit on an image side of the lens included in the retracting lens frame in an imaging enabled state, andthe light blocking portion blocks light rays which do not pass the shutter unit. 6. The lens barrel according to claim 1, wherein the support frame includes a main body provided a specific distance away from the light blocking portion, andthe lens support portion is provided between the main body and the light blocking portion during the transition period between the imaging enabled state and the housed state. 7. The lens barrel according to claim 1, wherein the light blocking portion is provided on an object side of the lens during a transition period between an imaging enabled state and a housed state. 8. The lens barrel according to claim 7, wherein the light blocking portion has a major surface that is offset from the optical axis and that faces along the optical axis to block light rays that pass the opening portion. 9. The lens barrel according to claim 8, wherein the light blocking portion is a first light blocking portion, andthe frame body includes a second light blocking portion provided on the opening portion in order to block light rays which pass the opening portion and do not pass the lens included in the retracting lens frame. 10. The lens barrel according to claim 9, wherein the second light blocking portion has a major surface that is offset from the optical axis and that faces toward the optical axis to block light rays that pass the opening portion. 11. The lens barrel according to claim 1, wherein when in the housed state, the part of the lens support portion is housed in the opening portion such that the lens of the retracting lens frame is not aligned with the optical axis, andwhen in the imaging enabled state, the lens of the retracting lens frame is aligned with the optical axis to receive light that travels along the optical axis.
