CPC G01P 3/44 (2013.01) | 7 Claims |
1. A rotation detection device, comprising:
a detected member being mounted to a rotating member and being configured to rotate integrally with the rotating member; and
a sensor section being arranged to face the detected member,
wherein the sensor section comprises two magnetic sensors comprising a first magnetic sensor including a first detection section and a second magnetic sensor including a second detection section, each of the first detection section and the second detection section comprising a magnetism detection element for detecting a magnetic field from the detected member, and a housing portion comprising a resin mold provided to collectively cover the two magnetic sensors and having a facing surface facing the detected member,
wherein the first and second detection sections of the two magnetic sensors are separated from each other,
wherein a minimum distance between the first and second detection sections of the two magnetic sensors is 0.05 mm or more and 2.00 mm or less,
wherein the resin mold enters into a space between the first and second detection sections of the two magnetic sensors,
wherein the first detection section and the second detection section are arranged side-by-side along a rotational axis line direction of the rotating member, and
wherein the first detection section is tilted with respect to the second detection section.
