Abstract

Above the level of a toothed disc (26), a sensor is fastened to a base member (23) by means of a lateral retaining arm (24). The retaining arm contains a guide bore (13) which extends vertically to the fastening surface (12) of the base member (23) and which receives in a sliding fit a substantially circular-cylindrical carrier member (11) which is formed with a central bore (33) for receiving a fastening bolt (15) screwed into a threaded bore (22) of the base member (23). The carrier member (11) extends into the inside of the guide bore (13) and terminates in an upper annular end surface (10). A circlip (14) whose external diameter corresponds to the diameter of the guide bore (13) seats on the end surface. In the area of the circlip, the bolt (15) has a cone-like enlargement (16) which, when the fastening bolt (15) is tightened, will be seated on the circlip (14) and press it axially against the carrier member (11) and radially against the wall defining the guide bore (13).
