PROBLEM TO BE SOLVED: To provide a projection display device for miniaturizing composition for vibration control. SOLUTION: A projector 1 includes a casing 3, a blade part 105, and a fan case 107 rotatably storing the blade part 105. The projector also includes: a second axial flow fan 81 arranged in the casing 3; and a plurality of vibration control members 167 having at least one of elasticity and viscosity by being arranged at a plurality of positions of a circumferential direction out of an outer peripheral face part 107a of the fan case 107 surrounding the blade part 105 around a rotating shaft of the blade part 105 and being interposed between the casing 3 and the fan case 107.
