Abstract: A first lens group unit 20 includes a lens L2, a blacked-out portion L2b, a lens frame 22, and an injection hole 21a. The lens L2 has a thrust surface L2d that intersects the direction of the optical axis AX, a thrust surface L2c on the opposite side from the thrust surface L2d, and an edge surface L2e that connects the thrust surface L2d and the thrust surface L2c. The blacked-out portion L2b is provided to an edge surface L2e of the lens L2, and suppresses the reflection of light incident on the lens L2 on the edge surface L2e. The lens frame 22 has a substantially cylindrical shape, and holds the lens L2, which is inserted from the thrust surface L2d side along the cylindrical inner peripheral surface 22a. The injection hole 21a is used to bond the lens L2 and the lens frame 22 with an adhesive applied to the thrust surface L2c.

Abstract: A lens barrel 10 comprises fourth lenses L4a and L4b, a substantially cylindrical fourth lens group unit 20, and a substantially cylindrical cam frame 14. The fourth lens group unit 20 holds the fourth lenses L4a and L4b and has a plurality of cam pins 22a to 22c and 23 protruding in the radial direction. The cam frame 14 is disposed substantially coaxially with the fourth lens group unit 20, and has a plurality of cam grooves 14c that are formed in a direction intersecting the optical axis direction and engage with the cam pins 22a to 22c and 23; assembly grooves 14d and 14f that are provided contiguously with the cam groove 14c, engage with the cam pins 22a to 22c and 23 in the mounting and assembly of the fourth lens group unit 20, and guide these cam pins from the end portion to the cam groove 14c in the optical axis direction; and a concave portion 14g that holds the cam pin 23 in the assembly groove 14f in the assembly of the fourth lens group unit 20.

Abstract: A lens barrel 10 comprises a fourth lens group unit 20, cam pins 22a and 22b, a biasing pin 23, a cutout portion C1, a substantially cylindrical first lens group unit 13, and a plurality of rectilinear guide portions 25. The fourth lens group unit 20 has a substantially cylindrical main body portion 21 that holds a lens L4a, etc. The cam pins 22a and 22b are provided to the fourth lens group unit 20, protrude in the radial direction, and engage in the cam grooves 14b of the cam frame 14. The biasing pin 23 is provided to the fourth lens group unit 20, is supported so as to bias in the radial direction, and engages in the cam groove 14b. The cutout portion C1 is formed by cutting out the portion of the main body portion 21 of the fourth lens group unit 20 opposite the biasing pin 23 in the direction of the optical axis. The main body portion 21 of the fourth lens group unit 20 is provided continuously in the circumferential direction, from the biasing pin 23 to the cam pins 22a and 22b.

Abstract: A lens hood which is integrated with a lens cover is provided. The lens hood is attached in front of an imaging lens, and is configured to prevent undesired light incident on the imaging lens. The lens hood includes a lens cover having an upper door and a lower door, and a hood body. The hood body supports the upper door and the lower door so as to rotate the upper door and the lower door in opposite directions to each other about an axis orthogonal to an optical axis of the imaging lens, and has a storage space that stores the upper door and the lower door.
