Claims

[Scope of claim for utility model registration] 1. A magnetic sensor is placed facing the object to be detected,
In this magnetic sensor, a magnet is fixed to the surface opposite to the surface facing the detected object, and a yoke is fixed to the back side of the magnet, and the end of this yoke is attached to the detected object. A magnetic detector characterized in that the detectors are placed close to each other and face each other. 2. The magnetic detector according to claim 1, wherein the yoke extends in the longitudinal direction of the object to be detected, and both ends thereof are bent toward the object to be detected. 3. The magnetic detector according to claim 2, wherein the distance between the bent portions at both ends of the yoke is an integral multiple of the pitch of the detected portion of the detected object. 4. The magnetic detector according to claim 1, wherein the yoke extends in the width direction of the object to be detected, and both ends thereof are bent toward the object to be detected.
