PROBLEM TO BE SOLVED: To provide a motor having a sensor magnet fixing structure that can be excellently installed with a small number of components, can firmly fix a sensor magnet to a rotating shaft, and never loosens or drops out in the rotation direction, an electric power steering device and a vehicle.SOLUTION: In a sensor magnet fixing structure in a rotation angle sensor in which the rotation angle of a sensor magnet 200 secured to a rotation shaft 101 is detected by a magnetic detection element 181 provided at a confronting position, a step is formed at one end portion of the rotation shaft 101 to form a fixing support pole, a spring 160 is disposed on the step so as to surround the fixing support pole, a mount hole of the sensor magnet 200 is fitted to the fixing support pole to press the spring 160, a press plate 210 which is fitted to the fixing support pole and the sensor magnet 200 is secured to the tip portion of the fixing support pole, and the press plate 210 is pressed by a pin 150 to be inserted and fixed in a cylindrical hole of the fixing support pole. A convex portion is formed at the apex portion of the pin 150.SELECTED DRAWING: Figure 11

    【課題】少ない部品で組込み性良く、センサマグネットを回転軸に堅固に固定し、回り方向の緩みや抜けの生じないセンサマグネット固定構造を備えたモータ並びに電動パワーステアリング装置及び車両を提供する。【解決手段】回転軸101に取付けられたセンサマグネット200の回転角度を、対向位置に配設された磁気検出素子181により検出する回転角度センサにおけるセンサマグネット固定構造であり、回転軸101の一端部に段差を有して固定用支柱が形成され、固定用支柱を包囲して段差にスプリング160が配置され、センサマグネット200の装着孔が固定用支柱に装着されてスプリング160を押圧し、固定用支柱及びセンサマグネット200に係合する押えプレート210が固定用支柱の先端部に取付けられ、ピン150により押えプレート210を押圧して固定用支柱の円筒穴に挿入して固定する構造であり、ピン150の頂部に凸部が形成されている。【選択図】図11
