PURPOSE: To keep tips of wires at precise positions for a work in pressing the tips against the work by embedding the closely standing wires in rubber for the tips to be visible on the rubber surface.

CONSTITUTION: A wire brush is constituted of numerous standing wires 2 with their base ends being secured in a base material 1. These closely standing wires 2 are embedded within rubber 3, so that the tips 2A are visible. The base material 1 uses two disks with holes at the center, and the base ends of wires 2 are secured within the base material 1 consisting of these two disks. A bush 4 is fitted in the holes made in the two disks. When viewed from the side, it is constituted as shown in the figure, the wires 2 being embedded in the rubber 3 are exposed at the surface of the rubber 3. Accordingly, tips of wires are visible on the surface of rubber. Therefore, the wires do not open in bending by pressing tips of wires onto a work and rubbing the work.
