連結ピン。 A connecting pin for a bicycle chain comprising a pair of inner plates and a pair of outer plates, both of which are connected in a chain by overlapping both ends of the plates, the pin fitting of the outer plates. Flanges 2, 2 protruding radially outward are provided at both ends of the pin body 1 which is press-fitted into the hole to connect the inner plate and the outer plate, and at least one of these flanges 2, 2 is provided. The amount of protrusion of the flange 2 is set to be less than or equal to the sum of the elastic displacement amount of the flange 2 portion when press-fitting into the pin fitting hole of the pin body 1 and the expected elastic displacement amount of the pin fitting. At the same time, the outer surface of this one collar 2 is a tapered surface that tapers toward the edge, and a conical guide recessed toward the center is formed on the end surface of the other collar 2 of the pin body 1. A connecting pin for a bicycle chain, characterized in that a recessed portion 12 is provided.
