On the other hand, in a portion corresponding to the end skirting body 15, one of the two surfaces 15c and 15d orthogonal to the other end 15b is formed by the pillar 5 installed at the end of the wall surface 3. While the exposure is prevented, the other surface 15d is provided along the floor surface 4 and has a small step with the floor surface 4 so as not to obstruct walking or the like. Further, in the end baseboard 15, a right-angled corner is formed by the two surfaces 15c and 15d near the other end 15b, but the range is extremely small as a whole of the baseboard unit Z1. The accumulation of dust and the like hardly causes a problem, and even if it accumulates, it can be easily removed. In addition, depending on the structure of the wall surface 3, there may be a case where the pillar 5 is not provided at an end portion of the wall surface 3, a case where the skirting board 1 is provided only halfway of the wall surface 3, and the like. Since the amount of protrusion of the one surface 15a of the end baseboard 15 from the wall surface 3 is small, there is no problem in use.
[0043]
In the skirting board unit Z1 configured and installed as described above, the surface 1a of the skirting board 1 is a concave curved surface that is inclined downward from the upper end side to the lower end side. 1 covers a peripheral corner 8 at a right angle formed at the boundary between the wall surface 3 and the floor surface 4, and at the upper end of the skirting board 1, the surface 1 a and the wall surface 3 are obtuse. And at the lower end of the baseboard 1, the surface 1a thereof and the floor surface 4 are connected at an obtuse angle.
[0044]
Therefore, as the included angle between the two surfaces forming the corners at the upper and lower ends of the baseboard 1 is large, dust is prevented from adhering and accumulating to the extent possible, and even if dust adheres here. However, this can be easily and reliably removed by the cleaning tool. As a result, the skirting board 1 prevents dust and the like from remaining on the peripheral corner 8 formed by the wall surface 3 and the floor surface 4, thereby maintaining a good indoor sanitary environment and aesthetic appearance. Will also improve.
[0045]
Furthermore, in the skirting board unit Z1 of this embodiment, by forming the end of the skirting board 1 by the end skirting board 15, the skirting board 1 projects from the wall surface 3 toward the floor surface 4 side. In spite of the configuration in which the device is installed, it does not cause an obstacle such as walking, so that high safety in use is ensured.
