PURPOSE: To easily pack and unpack the optical device with simple structure by providing a lock means which is fitted in the recessed part of a lens part which is provided projecting and formed in the flank of a projecting mirror part and a lock means which is provided at the upper part of a housing and locks the top surface of the mirror part.
CONSTITUTION: When the optical device is shipped, the mirror part 5 is moved along a guide shaft 3 toward the flank 2b of a frame 2 to make a stopper 14 abut on the flank 2b. Then the lens part 4 is moved along the guide shaft 3 and made to abut on the mirror part 5. At this time, the projection part 12 provided to the lens part 4 is fitted in the recessed part 13 of the lens part 5. In this state, the mirror part 5 is put under a bent part 16 formed at the upper part of the frame 2 and the mirror pat 5 is locked and inhibited from moving as shown by an arrow B together with the lens part 4. Consequently, the simple structure where a lock piece 15 is only provided inhibits the lens part 4 and mirror part 5 from moving as shown by arrows A and B, so the optical device can easily be packed and unpacked.
