Abstract:
A projection lens unit ( 15 ) of a projector ( 10 ) is disposed in a state in which an optical axis (CL) of the projection lens unit deviates from a center of an image forming panel ( 14 ); a first lens holder ( 43 ) of a lens barrel ( 40 ) includes holding pieces ( 55 a,  55 b ) that are provided at intervals in a circumferential direction of a first lens group (L 1 ) and are engaged with a first portion (A 1 ) of the first lens group positioned on a side to which the image forming panel is shifted, and a holding piece ( 55 c ) that is engaged with a second portion (A 2 ) of the first lens group positioned on a side opposite to the side to which the image forming panel is shifted; and the linear expansion coefficient of each of the holding pieces is lower than the linear expansion coefficient of the holding piece.

Claim (Index 6):
The projection lens unit according to  claim 2 ,\n wherein the first material which forms the holding pieces engaged with the first portion and the second material which forms the holding pieces engaged with the second portion are composite materials, which are obtained by adding fillers for adjusting linear expansion coefficients to a common resin base material, and content percentages of the fillers are different from each other.
