| Zusammenfassung: | An optical axis adjusting device for adjusting an eccentricity of an adjusting lens group of the lens system with respect to a fixed lens group of the lens system, by moving the adjusting lens group in a direction orthogonal to an optical axis of the fixed lens group, includes an adjusting lens group support member movable in a direction orthogonal to the optical axis of the fixed lens group, and a resilient cylindrical chuck made of a resilient material which is provided with the adjusting lens group support member, the resilient cylindrical chuck having a lens holding portion which is formed at an open end of the resilient cylindrical chuck so as to surround and resiliently hold the adjusting lens group. |
