Document Type and Number:
Japanese Patent JP6968038
Kind Code:
B2
Abstract:
The utility model provides a high-durability rotation detection device capable of preventing foreign matters such as iron powder from adhering to a sensor body. A rotation detection device (100) is provided with: a sensor body (10), the tip of which is provided away from the circumferential surface of a rotating body (5), and which generates a pulse signal in accordance with a change in magnetic flux accompanying the rotation of the rotating body (5); and a movable body (20) which has a cover part that covers the tip of the sensor body (10), and which is movably supported by the sensor body (10) in an A direction that is substantially perpendicular to an axis (CL1) passing through the center of the sensor body (10) and is substantially perpendicular to the rotational axis (6) of the rotating body (5). The movable body (20) further has a pressure-receiving section that comes into contact with the lubricating oil brought up by the rotation of the rotating body (5), and is provided so asto move in the A direction by the oil pressure acting on the pressure-receiving section.
