The lens holding portion includes first and second holding portions allowed to contact surfaces opposite to each other of a marginal portion (le) of the lens. The first holding. portion (4) is allowed to contact regions (1d) rearward from positions having a first circumferential angle of larger than 45 DEG and smaller than 70 DEG to both circumferential sides from a 0 DEG position in the marginal portion. The second holding portion (3) is allowed to contact regions (1f) rearward from positions having a second circumferential angle larger than the first circumferential angle in the marginal portion.
