ト。 It has a main body that houses a lamp that serves as a light source and a reflector that is shaped like a bowl surrounding the lamp and reflects the luminous flux emitted from the lamp in a predetermined direction, and is detachably attached to the main body. A mask that adjusts the shape and size of a spot formed by the emitted light beam has an attachment attached to one end of the main body, and the mask connects a plurality of first light-shielding blades to a single first light-shielding blade. The iris shutter can be operated at the same time to change the aperture diameter of the circularly formed transmitting part, and the second levers attached to the plurality of second light-shielding blades can be operated to change the aperture diameter of the circular transmission part. a cutter that changes the shape of the opening of the transmitting portion formed in the shape, the first lever being movably disposed in a substantially parallel plane in front of the opening of the reflector;
The attachment part of the iris shutter and the cutter are formed in the same shape, and the attachment has a plurality of notches from which the second lever can protrude to the outside, and one of the notches is attached to the first lever. The lever is made to protrude outside and the first
The spot light is set to a size that restricts the movement range of the lever, and the tip edge of the reflector faces the mask and extends as a light-shielding piece that covers the notch.
