Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the broken pieces of a lamp from being scattered to the outside from a vent hole even if the lamp is broken when a lamp box is detached from a projector device. SOLUTION: A metal halide lamp 2 is housed in a box 20. The vent holes 26 provided on the right and left side surfaces of the box 20 are covered with a shutter 40 when the lamp box 100 is detached from the projector device. Energizing force is given to the shutter 40 by a spring 27 so that the vent hole 26 may be covered with the shutter 40. When the vent hole 26 is covered with the shutter 40, the shutter 40 is slid on the surface of the box 20 by a pin 42 so that the shutter 40 may not be opened by the force of pressing the shutter 40 from the inside of the box 20.
