Abstract
There are provided a lens unit, a camera system, and an elastic member that can prevent an annular elastic member from being entangled. The lens unit includes an optical system that includes at least one lens, a lens barrel that receives the optical system, a lens mount that is provided on one end side of the lens barrel and includes a plurality of bayonet claws, and an annular elastic member that is mounted on the lens mount. The elastic member includes a protruding portion that is positioned on the one end side and protrudes inward in a radial direction, and a dent that is positioned on an outer peripheral side opposite to the protruding portion so as to be closer to the other end side than the protruding portion.

A lens unit comprising:
- an optical system that includes at least one lens;
- a lens barrel that receives the optical system;
- a lens mount that is provided on one end side of the lens barrel in a direction of an optical axis and includes a plurality of bayonet claws;
- and
- an annular elastic member that is mounted on the lens mount,
- wherein the elastic member includes a protruding portion that is positioned on the one end side and protrudes inward in a radial direction, and a dent that is positioned on an outer peripheral side opposite to the protruding portion so as to be closer to the other end side of the lens barrel than the protruding portion in the direction of the optical axis, and
- the dent serves as fulcrum and allows the protruding portion of the annular elastic member to be displaced outward in the radial direction.
An annular elastic member comprising:
- a protruding portion that is positioned on one end side in a height direction and protrudes inward in a radial direction;
- and
- a dent that is positioned on an outer peripheral side opposite to the protruding portion so as to be closer to the other end side than the protruding portion in the height direction, wherein
- the dent serves as a fulcrum and allows the protruding portion of the annular elastic member to be displaced outward in the radial direction.
