To make it difficult for a stud pin buried into a hole for attaching a stud pin to come off and fall from the hole for attaching a stud pin.SOLUTION: The stud pin comprises: a tip part which contacts with a road surface; and a buried part which includes a trunk part which extends in one direction so as to be buried into the hole for attaching a stud pin and is fixed so that the tip part protrudes from an end surface, and an outer peripheral holding member held at the trunk part in such a condition as to cover a portion wider than at least semi-circle of the outer periphery extending in a direction perpendicularly intersecting with the extending direction of the trunk part in one part of the extending direction of the trunk part. The outer peripheral holding member comprises an outer peripheral part which is provided so as to abut around the outer periphery of the trunk part, and a protrusion part which protrudes from the outer peripheral part toward a side of the trunk part inwardly. The buried part expands the outer periphery of the outer peripheral holding member by pushing the outer peripheral part toward the outside through the protrusion part as the bottom surface of the trunk part opposed to a side of the end surface approaches the bottom of the hole for attaching a stud pin.SELECTED DRAWING: Figure 4

    【課題】スタッドピン取付用孔に埋め込まれたスタッドピンを、スタッドピン取付用孔から抜け落ち難くする。【解決手段】スタッドピンは、路面と接触する先端部と、前記スタッドピン取付用孔に埋め込まれるように一方向に延在し、前記先端部が端面から突出するように固定された胴体部と、前記胴体部の延在方向の一部分において、前記胴体部の前記延在方向と直交する方向に延びる外周の少なくとも半周より広い部分を覆う状態で前記胴体部に係止された外周係止部材と、を有する埋設部と、を備える。前記外周係止部材は、前記胴体部の前記外周に沿うように設けられた外周部と、前記外周部から前記胴体部の側に向かって内向きに突出した突出部と、を備える。前記埋設部は、前記端面と反対側の前記胴体部の底面が前記スタッドピン取付用孔の底に近づくに連れて前記突出部を通して前記外周部を外側に向かって押すことにより、前記外周係止部材の外周を拡張する。【選択図】図4
