At least two of a plurality of internal lugs distributed on the inner side thereof are engaged by at least two of the plurality of internal teeth of the at least one drive sprocket. The plurality of internal lugs is disposed to form at least one longitudinal row. At least two consecutive internal lugs are disposed at a first pitch from each other. The first pitch is longer than an arc length corresponding to the sprocket pitch.
