PROBLEM TO BE SOLVED: To provide a load sensor having high rigidity in an axial direction.SOLUTION: A magnetic load sensor 1 includes a pair of parallel plates 2, 3, and a connection piece 4 for connecting the parallel plates 2, 3. The connection piece 4 is arranged while having inclination with respect to the axial direction so that, when an axial direction load is applied to the pair of parallel plates 2, 3, the parallel plates cause relative displacement in a direction orthogonal to the axial direction due to bending of the connection piece 4. A magnetic target 5 is attached to the parallel plate 2, and magnetic sensor 6 is attached to the parallel plate 3. According to the relative displacement in the direction orthogonal to the axial direction of the parallel plates 2, 3, the magnetic target 5 and magnetic sensor 6 cause a relative displacement in the direction orthogonal to the axial direction.

PROBLEM TO BE SOLVED: To provide a load sensor for a direct acting actuator which is unlikely to cause hysteresis errors when used assembled with the direct acting actuator and suppresses axial length of the direct acting actuator.SOLUTION: The magnetic load sensor for a direct acting actuator detects the magnitude of a load in the axis direction, the load being applied to an object 22 by the direct acting actuator, has a flange member 2 for causing deflection by receiving reactive force of the load in the axis direction via a thrust bearing 41, a magnetic target 4 for generating a magnetic field, and a magnetic sensor 5 placed so that its relative position with respect to the magnetic target 4 changes as the flange member 2 warps, and forms a groove 10 where a rolling body 41B of the thrust bearing 41 rotates and contacts an end surface in the axis direction of the flange member 2.
Abstract:
A load sensor unit is provided which is less likely to suffer from hysteresis errors. The magnetic load sensor unit (1) includes a flange member (2), a support member (3) supporting the flange member (2) from the axially rearward side, a magnetic target (4) fixed to the flange member (2), a magnetic sensor (5) fixed to the support member (3). The magnitude of the load is detected based on the magnetic flux detected by the magnetic sensor (5). A load acting surface (6) of the flange member (2) to which the load is applied is formed at a position offset axially rearwardly relative to an axially forward surface (7) of the flange member (2).
