Abstract:
In order to provide a projection lens barrel and a projection display device that are capable of correcting the optical characteristics of a plurality of lens groups, a projection lens barrel, comprising a lens optical system causing light from an image display element to be formed as a projected image on a screen, also comprises correction mechanisms that move each of at least two lens groups along an optical axis and correct the optical characteristics to be corrected, said lens groups each having different optical characteristics for correction in order to suppress reduction in image quality of a projected image caused by changes in optical characteristics caused by temperature changes in the projection lens barrel.

Claim (Index 7):
The projection lens barrel according to  claim 1 , wherein a third correcting mechanism of each of the correcting mechanisms includes:\n a third correcting lens holding flame that holds a third correction lens group to be corrected by the third correcting mechanism;\n a rear side lens holding frame that holds a lens group disposed at rear side of the third correction lens group; \n a wave washer disposed between the third correction lens holding frame and the rear side lens holding frame; and \n an outer peripheral barrel that is disposed at outer circumference of the thermal deforming frame of the second correcting mechanism disposed at a front side of the third correction lens holding frame and attached to the front end of the rear side lens holding frame; \n wherein a thermal deforming frame of the third correction mechanism is situated and pinched between the third correction lens holding frame and the outer peripheral barrel in a state of being energized forward by the wave washer.
