Abstract

Selon la présente invention, afin de fixer un capteur d'angle de rotation (20) à un corps de retenue de capteur (10) : un élément intercalé (30) est monté rotatif sur une partie cylindre de capteur de fixation (21) du capteur d'angle de rotation (20) à une position prescrite dans la direction axiale d'un axe central de cylindre (Cs); et la partie cylindre de capteur (21) est ajustée dans une paroi de retenue cylindrique (11) du corps de retenue (10) à une position et une orientation prescrites permettant la détection par le capteur d'angle de rotation (20) de l'angle de rotation d'un corps rotatif à détecter (1), ce qui permet de limiter la rotation du capteur d'angle de rotation (20). Étant donné que l'élément intercalé (30) est fixé au corps de retenue (10), un mouvement axial du capteur d'angle de rotation (20) est limité. Ainsi, le capteur d'angle de rotation peut être fixé au corps de retenue à une position et une orientation prescrites par une opération de fixation simple.
