That is, the known eaves rod support tool B is integrally formed by connecting the fixing plate portion 2a attached to the mounting surface, the eaves support portion 3 supporting the eaves rod, and the arm portion 4. Thus, a front ear support portion 31 and a rear ear support portion 32 are provided at both ends of the heel support portion 3. The eaves support B is fixed to a mounting surface such as a nose cover plate of the eaves by a fixing screw inserted through a screw hole 5a formed in the fixing plate portion 2a. Is supported by hanging.

  On the other hand, for example, a wooden nose cover plate is often used as the above-mentioned mounting surface, but recently, the surface of the wooden nose cover plate is made of a synthetic resin-containing paint in terms of corrosion prevention, fire prevention measures or aesthetics. It is common practice to paint with or cover with a metal cover. As this metal cover, a decorative steel plate whose surface is covered with a vinyl chloride resin material, a so-called vinyl chloride steel plate is often used.

  Meanwhile, as the eaves support B, in addition to those obtained by integrally molding a conventionally used vinyl chloride resin, in recent years, polycarbonate resin, polyester resin, ABS resin, and the like are used for mechanical strength and weather resistance. It has been widely used because it has advantages such as excellent properties and high transparency. However, when a vinyl chloride steel plate is attached to the surface of the nasal cover, the vinyl chloride resin material that coats the steel plate contains various chemical components such as plasticizers, ultraviolet absorbers, anti-aging agents, and flame retardants (hereinafter, These are transferred to the surface side of the coating layer, and, for example, permeate into the surface side of the fixing plate portion 2a of the eaves supporting member B made of polycarbonate resin and exert a deterioration action. When the support B is cracked or cracked, it is a serious problem that the heel support part 3 falls off the fixed plate part 2a.

In order to solve the above problem, Japanese Patent Application Laid-Open No. 9-165888 discloses a synthetic resin made of a mounting portion that is attached to a mounting surface of a building, and a support portion that protrudes from the front surface of the mounting portion. In the scissor support, a scissor support characterized in that a prevention layer for preventing the migration of the plasticizer is provided on the side of the mounting portion that comes into contact with the surface to be mounted. Even if a decorative steel plate coated with a vinyl chloride resin containing a plasticizer is attached to the surface of the nose cover plate, the attachment portion of the heel support made of polycarbonate resin is subject to mechanical strength deterioration by the plasticizer. If not, the effect is stated.
