Abstract

PURPOSE:To improve accuracy at the time of assembly and simplify assembly by a method wherein a Hall IC is stored in contact with a positioning part while the Hall IC is pressed against the positioning part by an elastic member interposed between a frame and the Hall IC. CONSTITUTION:Positioning parts 11a,11b of a Hall IC 2 are formed by inner walls of a storing part 11. At the time of assembling, the IC 2 and a flux guide 42 are inserted into the storing part 11, while the flux guide 42 with a magnet 5 fixed is fitted into a flux guide holder 13 to determine relative positions of the respective components. As a result error in size of the IC 2 itself and a frame is made within an allowable range so that assembly can be easily performed with high positioning accuracy.
