従来の技術
従来の回転体への速度検出用磁石の固定構造は第４図に
示すように、回転体１端面に速度検出用磁石２を単にそ
れぞれの接合面を接着剤にて固定していた。Conventional technology As shown in Fig. 4, the conventional structure for fixing a speed detection magnet to a rotating body is to simply fix the speed detection magnet 2 to the end face of a rotating body 1 using adhesive. .
発明が解決しようとする課題
これら従来の技術による方法では、回転体１七速度検出
用磁石２は同心状にして固定しなければならないため位
置決めが困難で特別に治具が必要となり、生産性も悪く
コストアップの要因となっている。Problems to be Solved by the Invention In these conventional methods, the rotating body 1 and the speed detection magnet 2 must be fixed concentrically, making positioning difficult and requiring a special jig, which reduces productivity. Unfortunately, this is a factor in increasing costs.

定するようにしたものである。Means for Solving the Problems Therefore, several protrusions and recesses were provided corresponding to each other on the speed detection magnet that detects the speed of the rotating body and the seat on the end face of the rotating body that fixes the speed detection magnet. Fit and secure each piece. In addition, the speed detection magnet is made into a ring shape, and several protrusions are provided on the seat on the end face of the rotating body to which the speed detection magnet is fixed, and the protrusions are fitted with the inner diameter of the speed detection magnet to fix it. This is what I did.
作用
本発明によれば、回転体と速度検出用磁石を同心状に固
