ABSTRACT:
A Hall effect type sensing device comprises a magnetic circuit, a Hall transducing element arranged in the magnetic circuit to output a signal depending on a change in magnetic flux, a magnetic flux changing member which is able to change the magnetic flux in the magnetic circuit, a gap part which allows the magnetic flux changing member to move therein, and a frame member having its one side provided with a recessed portion forming the gap portion, and having its other side provided with an accommodation portion at a position adjacent to the recessed portion, the accommodation portion housing the Hall transducing element and a member forming the magnetic circuit.
