PROBLEM TO BE SOLVED: To provide a photoelectric separation type sensor having a simple structure and preventing an optical base support frame from loosening.SOLUTION: A photoelectric separation type sensor 1 comprises: an optical base support frame 19 that holds an optical base 23 and is set on a sensor base 11 as rotatable around a shaft 39; and horizontal angle adjusting means 25 to adjust an optical axis L in a horizontal direction of the optical base 23 by rotating the optical base support frame 19 in the horizontal direction. The horizontal angle adjusting means 25 includes a horizontal angle adjusting spring 35 that imparts a horizontal rotational force to the optical base support frame 19 and presses the optical base support frame 19 to tilt forward. |
