Abstract
Disclosed is a photoelectric tilt-detecting sensor which, while simple in structure, is reduced of traveling-around of light transmitted therein to thereby improve the signal-to-noise ratio. The tilt-detecting sensor has a light-emitting element and a light-receiving element respectively fixed in an opposed relation in a main body, and slant surfaces provided between the light-emitting element and the light-receiving element to define a space in the main body. The slant surfaces has an elongate groove so that a spherical ball is allowed to stably move therealong. A lid integral with the main body enables bending thereof to enclose the space of the main body. These lid and the main body is formable in one body by using dies through simplified processes, realizing large-scaled production.
