とする自転車用多段スプロケツト装置。 A multistage sprocket device comprising at least one large-diameter sprocket 1 and at least one small-diameter sprocket 2, in which each of the sprockets 1 and 2 is pulled out from one interdental center O1 of the small-diameter sprocket 2. The combination is such that one interdental center O 2 of the large diameter sprocket 1 is located on the tangent line, and each interdental center O 1 , O
2 is an interval that is an integer multiple of the chain pitch, and the first tooth 11 facing the rear side in the driving rotation direction of the inter-tooth center O 2 in the large diameter sprocket 1 and the rear side of the first tooth 11 in the driving rotation direction. The second tooth 12 adjacent to the second tooth 12 and the third tooth 13 adjacent to the rear in the drive rotation direction of the second tooth 12 are connected to each of these teeth 11 to 13.
The other teeth other than the small diameter sprocket are displaced toward the small diameter sprocket side to provide easy meshing teeth, while the first tooth 11 is provided with a chain for changing from the small diameter sprocket 2 to the large diameter sprocket 1 on the side opposite to the small diameter sprocket. In addition to providing a chain guiding surface 11a for guiding, the second tooth 12 is displaced relative to the first tooth 11, and the third tooth 13 is displaced relative to the second tooth 12, respectively, to the side opposite to the small diameter sprocket. Features a multi-stage sprocket device for bicycles.
