特徴とする自転車用多段スプロケツト装置。 It comprises at least one large-diameter sprocket 1 and at least one small-diameter sprocket 2, and the difference in the number of teeth between these sprockets 1 and 2 is a plurality of teeth, and the number of teeth of the large-diameter sprocket 1 is greater than the number of teeth described above. It is a multi-stage sprocket device with a number of teeth that is not an integral multiple of the difference, and among a plurality of arbitrary positions obtained by dividing the number of teeth of the large diameter sprocket 1 by the difference in the number of teeth, the largest one on the rear side in the rotational direction with respect to the arbitrary position The interdental center O 1 at one arbitrary position having the number of teeth, and the interdental center O
1. A multi-stage sprocket device for a bicycle, characterized in that the spacing between the small-diameter sprocket 2 located on the forward side in the rotational direction relative to the sprocket 1 and an arbitrary tooth center O2 is an integral multiple of the chain pitch.
