  • Publication number: 20180279766
    Abstract: A cleaning implement equipped with: a shaft part having an insertion end section and a base end section; and a cleaning part comprising an elastomer and capable of cleaning a gap. The cleaning part has a cleaning-part body and a guide part for projecting farther outward in the axial direction than the insertion end section, and guiding the insertion of the cleaning-part body into a gap. The projection dimension of the guide part from the insertion end section is equal to or greater than the thickness of the cleaning-part body, and the guide part has a shape that can be elastically deformed so as to be displaced relative to the insertion end section in the axially perpendicular direction.

  • Publication number: 20180256298
    Abstract: [Problem] To provide a base part, an interdental cleaning tool, and a method for manufacturing the interdental cleaning tool, capable of preventing bending of a shaft part when a resin material is filled from an insertion end. [Solution] A base part includes a shaft part (20) and a grip part (30). The base part is used for forming an interdental cleaning tool by filling, inside a metal mold having a shape that forms a filling space around the shaft part (20), a resin material into the filling space with the shaft part (20) clamped by a holding pin. The shaft part (20) includes a first guide groove (24) formed on one side with respect to an axially parallel plane and a second guide groove (26) formed on the other side with respect to the axially parallel plane.
