  The present invention relates to a protective member that is fixed to an edge or the like of a metal plate or the like disposed in a housing and protects an electric wire, piping, or the like in the housing from the edge or the like.

  2. Description of the Related Art In recent years, housings such as home appliances, and housings including electrical devices and electronic devices are provided with, for example, power supply wires or piping for cooling the inside of the housing. These electric wires, pipes, and the like are in contact with, for example, an edge of a metal plate arranged in the housing. Further, for example, the electric wire and the piping are in contact with the edge of the opening formed on the outer wall (metal plate) of the housing, and are drawn out of the housing through the opening.

  In general, electric wires and pipes are exposed (exposed), so if they come into contact with the edge of a metal plate or the edge of an opening, they may be worn away and damaged due to interference, etc. Etc. may occur. Therefore, a protective member is attached and fixed to the edge of the metal plate and the edge of the opening in order to protect the electric wire, the pipe and the like and prevent interference. Such a protective member is made of plastic, for example, and is, for example, a grommet.

  As shown in FIG. 8A, the protection member 100 has, for example, a substantially U-shape in the cross-sectional shape in the Y-axis direction (width direction). Such a protective member moves toward the metal plate 104 (edge 106) along the arrow (−Z-axis direction) shown in FIG. 8A. For example, as shown in FIG. Attached to and fixed.

  As shown in FIG. 8C, the protection member 100 is attached and fixed to the metal plate 104 by being attached (inserted) to the edge 106. A protective member 100 shown in FIG. 8D is attached to the edge 106 and further attached to the metal plate 104 and fixed by an adhesive 108. The same applies to the case where the protective member 100 is attached to and fixed to the edge of the opening.
