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 1):
A projection lens unit of a projector projecting light, which is applied to an image forming panel from a light source, onto a projection surface as image light and disposed in a state in which an optical axis of the projection lens unit deviates from a center of the image forming panel, the projection lens unit comprising:\n a lens barrel that is provided with one or more lens groups and one or more lens holders holding the lens groups, respectively, wherein at least one of the lens holders includes a plurality of holding pieces that are provided at intervals in a circumferential direction of the lens group held by the lens holder and are engaged with an outer peripheral portion of the lens group, of a first portion and a second portion of the lens group where the lens group is divided as to the two portions by a plane perpendicular to a shift direction in which the image forming panel is shifted from the optical axis and including the optical axis, the plurality of holding pieces including one or more holding pieces engaged with the first portion, which is positioned on a side to which the image forming panel is shifted, and one or more holding pieces engaged with the second portion that is positioned on a side opposite to the side to which the image forming panel is shifted, and a linear expansion coefficient of a first material, which forms the holding pieces engaged with the first portion, is lower than a linear expansion coefficient of a second material that forms the holding pieces engaged with the second portion.
