Abstract:
Tensioning device for a traction means, comprising a tensioning shoe (1), that tensions the traction means,and comprising a further base element (3), on which the tensioning element (1) is mounted for pivoting on a pivot axle (2), a spring means (4) arranged between the elements (1, 3) urging the tensioning element (1) against the traction means, wherein one of the two elements (1, 3) comprises two horseshoe-shaped spaced-apart fork arms (5, 10) each of which comprises a mounting eye (6, 11) having a radial mounting aperture (7, 12) for radially receiving the pivot axle (2), and the other of the elements (1, 3) comprises a radial projection (1, 3) which engages between the forks (5, 10) and is overlapped by the forks (5, 10) on both the elements (1, 3) for snap engagement without a separate fastener, there are corresponding arranged retention surfaces (8, 9) which extend coaxially with the pivot axle (2) and which, within an operation-dependent pivoting range of the tensioning device, are situated opposite each other and face each other, a radial displacement of the pivot axle (2) out of the radial mounting aperture (7, 12) being prevented by a contact of the retention surfaces (8, 9) with each other.
