To provide a braille stud that is hard to come off easily after installation, and is hard to leave trace in the floor material, while facilitating installation with a simple configuration.SOLUTION: A braille stud includes a rivet body and an engageable rivet acceptor. A base and a shaft part to set up from the base are provided to the rivet body. The rivet acceptor is provided with a cylindrical bearing where the base part and the shaft part are inserted therein. The bearing is provided with an inner wall part constituting an inner circumferential surface of the bearing, an outer wall for constituting an outer circumferential surface of the bearing, a ceiling for connecting ends together in the direction to set up the inner wall part and the outer wall part, and a cavity provided between the inner wall part and the outer wall part. A protrusion is provided in the inner wall part, In the shaft part, there is provided a groove engageable with the protrusion when the shaft part is inserted into the bearing.SELECTED DRAWING: Figure 4
【課題】簡易な構成で取り付けを容易にしつつ、取り付け後は容易に外れにくく、かつ、床材に跡が残り難い点字鋲を提供する。【解決手段】鋲体及び嵌合可能な鋲受体を備えた点字鋲において、鋲体に、基部及び基部から立設する軸部を設け、鋲受体に、ベース部及び軸部が挿入される筒状の軸受部を設け、軸受部に、軸受部の内周面を構成する内壁部、軸受部の外周面を構成する外壁部、内壁部及外壁部の立設方向の端部同士を連結する天井部、内壁部と外壁部との間に設けられる空洞部を設け、内壁部に凸部を設け、軸部に、当該軸部を軸受部に挿入した際に凸部と嵌合可能な溝部を設ける。【選択図】図４
