PROBLEM TO BE SOLVED: To provide an elevation mechanism for a projector achieving the reduction of cost by obtaining a mechanism making an elevation member freely ascend/descend by depressing an elevation button with simple constitution comprising a small number of parts. SOLUTION: By depressing the elevation button 3, the actuation projection 3c of the elevation button 3 presses the action piece 6a of a turning member 6 to turn the turning member 6, so as to release meshing of the tooth groups 6c and 12c of an actuation piece 6b and the leg part 12a of the elevation member 12, and the foot part 12b of the elevation member 12 is protruded after making the elevation member 12 freely ascend/descend.
