PROBLEM TO BE SOLVED: To accurately position a sensitivity element of a sensor with a specified space distance from a corder opposite to the corder, while fixing a bearing in the inside of a housing and while preventing the whole relative movement of the sensor against the corder. SOLUTION: The assembly is provided with the bearing 1 equipped with an information detection device and the housing 2 in which the bearing is fitted inside. The information detection device is provided with the corder 11 and the sensor 12 with at least two sensivity elements 13 which can detect pulses. The housing 2 is disposed to enable the radial fixation of the bearing 1 and has a shoulder 15 to enable the axial fixation of the bearing 1 at the rear side. In the assembly, the sensor 12 is made in a single piece fashion provided with a plurality of elastic tongues 19 fixing the bearing 1. The tongue 19 is disposed to cooperate with a recess 22 formed on the housing 2 so as to fix the bearing 1 at the forehead. |
