Abstract
The invention relates to a tensioning device (1) of a traction mechanism drive, comprising a base part (2) and a pivot arm (9), between which base part (2) and pivot arm (9) is inserted a torsional spring (17) which exerts both a torque on the pivot arm (9) and also a spreading force between the base part (2) and the pivot arm (9). To axially secure the pivot arm (9) to the base part (2), a latching connector (10) is provided which has a perforated disc (11) which is supported on a bearing pin (3) of the base part (2) and which extends radially into a region of the hub (8) of the pivot arm (9). An axially projecting extension (12) of the latching connector (10) engages into a receptacle (5), which is designed as a stepped bore (4), of the bearing pin (3), wherein an end region (14) is supported, in a radially flared fashion, on a step (15) of the receptacle (5).
