Abstract:

To inexpensively provide a rotation speed detecting device by using a detecting part and a fixing member in many ways.

A rotation speed detecting device 1 includes an annular fixing member 10 attached to an outer peripheral side of a rotation detecting object (not shown); a case 11 attached to the fixing member 10; and a detecting part 12 attached to the case 11 and opposing to the rotation detecting object to detect the rotation speed of the rotation detecting object. The case 11 is provided with an abutting part 11b on which the detecting part abuts at a predetermined position and deciding an attaching position of the detecting part 12. While the case 11 is attached to the fixing member 10 and the detecting part 12 is attached to the case 11, the fixing member 10, the case 11, and the detecting part 12 are fixed by a resin mold part 13 formed by resin molding.
