The bottom plate 3h is integrally formed. The first side wall 4n is formed such that its lower end surface is bent at a right angle, and the bottom plate 3h is formed such that both end portions are formed in a flat plate shape and the middle portion is curved. Therefore, the lower surfaces of the first side walls 4n and 4n and the lower surfaces of both end portions of the bottom plate 3h are flush with each other to form a contact surface 3a that contacts the construction surface 1. The bottom plate 3h is provided with fixing holes 4c and 4c for fixing the base 4 to the construction surface 1, and is screwed or driven into the construction surface 1 through the fixing holes 4c and 4c. The base 4 is attached and fixed to the construction surface 1 by a fixing tool such as a screw or a nail. Further, the bottom plate 3h is positioned such that the end portions of the bends are less than the respective end portions of the first side walls 4n and 4n, that is, the end portions of the side walls 3j and 3j. Is a contact surface 4d against which the end surface 2a of the straight protective cover 2 (specifically, the end surface of the bottom plate 2j) abuts. Therefore, the portion of the first side walls 4n, 4n that protrudes from the abutting surface 4d becomes the first connection port 4e that constitutes a part of the connection port 3c of the attached protective cover 3.

  Further, the upper surface of the first side wall 4n becomes the mating surface 4h, and the base 4 is mated with the lower surface of the cover 5 that becomes the mating surface 5i of the second side wall 5n described later when the cover 5 is assembled. It will be. Then, from the first side wall 4n, engaging projections 4i and 4i are formed so as to protrude from the inward position thereof, and a claw-like first locking is formed on the inner peripheral surface of the first side wall 4n. Portions 4j and 4j are formed. And the protrusions 4k and 4k are formed in the internal peripheral surface of the 1st side wall 4n so that this 1st latching | locking part 4j may be pinched | interposed.

  The cover 5 is made of, for example, a synthetic resin, and includes the second side walls 5n and 5n constituting a part of the side walls 3j and 3j of the attached protective cover 3, and the top plate 3i connecting the second side walls 5n and 5n. Are integrally formed. Therefore, the side wall 3j of the attached protective cover 3 is formed by the second side wall 5n and the first side wall 4n of the base 4. Each end portion of the cover 5 serves as a second connection port 5c constituting a part of the connection port 3c of the attached protective cover 3. That is, the connection port 3 c of the attached protective cover 3 is formed by the second connection port 5 c and the first connection port 4 e in the base 4.

  The cover 5 is provided with first and second guide portions 5p and 5q as the guide portion 3d. The first guide portion 5p is formed so as to protrude obliquely from the inner peripheral surface of the top plate 3i toward the second connection port 5c side on the back side of the second connection port 5c, and both the second side walls 5n, It extends over 5n (see FIGS. 18 and 24). Therefore, the first guide portion 5p is positioned outside the bend of the attached protective cover 3. The back side surface (that is, the front surface) of the first guide portion 5p becomes the first guide inclined surface 5r as the guide inclined surface 3e, and the first guide inclined surface 5r is formed from the top plate 3i. It is formed so as to be inclined toward the second connection port 5c as it is further away. The second guide portion 5q is formed to be curved so as to extend over the second side wall 5n, the first guide portion 5p, and the top plate 3i (see FIGS. 18 and 24). And the surface in this 2nd guide part 5q becomes the 2nd guide inclined surface 5s as the guide inclined surface 3e. By the way, the first guide portion 5p protrudes obliquely from the top plate 3i having a constant thickness and extends so as to extend over the second side wall 5n (side wall 3j) having a constant thickness. Since the meat thinning Q is provided between the top plate 3i on the back side, the occurrence of sink marks on the top side of the top plate 3i or the second side wall 5n (side wall 3j) can be prevented. Similarly, the second guide portion 5q extends over the second side wall 5n (side wall 3j) having a constant thickness and the top plate 3i, and the second side wall 5n (side wall 3j) on the back side of the guide portion 5q. Since the meat thinning Q is provided therebetween, it is possible to prevent the occurrence of sink marks on the front side of the second side wall 5n (side wall 3j) or the top plate 3i.
