Rotation angle sensor for drive shafts, has elastic flat spring inserted into groove, adjacent to connection hole with drive shaft, so that flat spring is elastically attached to protruded portion of drive shaft

摘要

A rotor (12) is fixed to the shaft (22) by inserting the flat portion of the shaft in the connection hole (13). A partition wall is formed between the connection hole and the groove formed adjoining the connection hole. An elastic curve-shaped flat spring (17) is inserted into the groove, and is elastically attached to the protruded portion of the drive shaft.
