Magnetic load sensor unit
First Claim
1. A magnetic load sensor unit comprising:
- a flange member configured to be deflected when an axial load is applied;
a support member supporting the flange member, the support member including a top surface abutting a bottom surface of the flange member;
at least one magnetic target which generates a magnetic field; and
at least one magnetic sensor for detecting the magnetic field generated by the at least one magnetic target;
wherein one of the at least one magnetic target and the at least one magnetic sensor is fixed to one of the flange member and the support member, and the other of the at least one magnetic target and the at least one magnetic sensor is fixed to the other of the flange member and the support member, such that when the flange member is deflected, the at least one magnetic target and the at least one magnetic sensor move relative to each other, whereby a magnitude of the applied axial load is detectable based on the magnetic field as detected by the at least one magnetic sensor.

Abstract
A magnetic load sensor unit is provided which can detect a load with a minute movement of its part, and which is durable and less likely to be influenced by temperature. The sensor unit includes a flange member (1) deflectable when an axial load is applied, a support member (2) supporting the flange member (1), a magnetic target (3) which generates a magnetic field, and a magnetic sensor (4) for detecting the magnetic field generated by the magnetic target (3). The magnetic target (3) and the magnetic sensor (4) are fixed to the flange member (1) and the support member (2), respectively, such that when the flange member (1) is deflected, the magnetic target (3) and the magnetic sensor (4) move relative to each other, whereby magnitude of the load can be detected based on the magnetic field detected by the magnetic sensor (4).
