PURPOSE:To provide the inexpensive optical space transmission device which can prevent optical axis misalignment with simple constitution and procedures. CONSTITUTION:The device which executes communication with space propagated light signals is provided with an angle adjusting base holding this device. The angle adjusting base consists of a base 1 holding the optical space transmission device, a rotating direction supporting part 2, a magnet 3, a weight 5, a post, and a base part 7 coupled with a post, etc., and the post, etc., are free in respective directions of rotation and inclination. The optical space transmission device is held together with a holding base 1 in the adjusted state by the magnetic force generated by the magnet 3 and the gravity acting on the weight 5 in the respective directions of the rotation and inclination after the angle adjustment is completed by tightening bolts 4, 6. |
