Abstract:
1. An optical element holding structure comprising: a first holding member adapted to hold an optical element; a second holding member which is positioned on an outer diameter side of said first holding member and adapted to hold said first holding member; a third holding member which is positioned on an outer diameter side of said second holding member and adapted to hold said second holding member; a plurality of first elastic members which are positioned between said first holding member and said second holding member in a radial direction thereof, each of which has an inner diameter side connected to said first holding member, each of which has an outer diameter side connected to said second holding member, and which can elastically deform in the radial direction; and a plurality of second elastic members which are positioned between said second holding member and said third holding member in a radial direction thereof, each of which has an inner diameter side connected to said second holding member, each of which has an outer diameter side connected to said third holding member, and which can elastically deform in the radial direction, wherein said plurality of first elastic members and said plurality of second elastic members are arranged in a circumferential direction about an optical axis of the optical element as the center, and a phase of said plurality of first elastic members is shifted from a phase of said plurality of second elastic members in the circumferential direction about the optical axis of the optical element as the center.
