PROBLEM TO BE SOLVED: To improve workability in work for adjusting the position of the lens barrel of a projector device. SOLUTION: The lens barrel supporting device is provided with a moving member 32 to which the lens barrel 11 is attached, and a fixing member 31 movably supporting the moving member 32 along a prescribed surface. The movement of the moving member 32 by gravity to which the lens barrel 11 is attached by gravity is prevented by a friction means 33 provided between the fixing member 31 and the moving member 32. The moving member 32 is moved with respect to the fixing member 31 by an operation means 35. The moving member 32 is prevented from being turned centering on an optical axis O by a rotation regulating means 34. The regulating means 34 is equipped with a swing guide 105 equipped with 1st and 2nd shaft parts 101 and 102. The 1st shaft part 101 is supported so that it can turn to the moving member 32 side and can slide in the shaft direction. The 2nd shaft part 102 is supported so that it can turn to the fixing member 31 side. COPYRIGHT: (C)2005,JPO&NCIPI
