PROBLEM TO BE SOLVED: To provide a rotation structure for an electronic device mounting fixture capable of more precisely and easily setting adjustment of a fitting angle to an appropriate direction in relation to a rotating direction of an electronic device installed in a cabin or the like. SOLUTION: Two uneven surfaces 11, 12 radially formed with the same pitch on the outer periphery and the inner periphery around a bearing portion 10 are provided, and a rotatable mounting fixture 9 on which these two protruded and recessed surfaces 11, 12 are disposed while shifted by an angle of half the pitch is provided. Two protruded and recessed surfaces 14, 15 radially formed with the same pitch as that of the protruded and recessed surfaces of this mounting fixture 9 on the outer periphery and the inner periphery around the bearing portion 10 are provided, and a mounting fixture 13 on which these two protruded and recessed surfaces 14, 15 are disposed while shifted by an angle of half the pitch is provided. Angle adjustment is executed in relation to the rotating direction of the mounting fixture 9 by fitting two protruded and recessed surfaces 11, 12 of the mounting fixture 9 with two protruded and recessed surfaces 14, 15 of the mounting fixture 13.
