It is preferable that the long cosmetic material has a structure in which a holding portion that sandwiches both side edges of the locking claw from both sides is provided on the back surface of the long decorative material. With such a structure, when a fixture is attached to the lower end of the outer wall of the building unit on the upper floor in the factory and the locking claw of this fixture is inserted into the holding part of the long decorative material from above, the locking claws are almost the same. Since it is a plate-like body that is thick and has both side edges substantially parallel to each other, the locking claw can be easily inserted into the holding portion. Moreover, since there are protrusions protruding to both sides at the center portions of both side edges of the locking claws, the protrusion stops when it is inserted up to these protrusions.

In this way, when the protrusion is inserted,
Since the lower end of the long decorative material is made to be the same as or above the floor beam or the lower end of the pillar of the building unit on the upper floor, this long cosmetic unit should be used when storing or transporting the building unit on the upper floor. The material will not break.

After transporting this building unit to the construction site and mounting and mounting the building unit on the upper floor on the building unit on the lower floor at the construction site, strong and long makeup is applied so that the protrusions enter the inside of the holding section. When the material is pushed downward, this long decorative material covers the gap between the outer wall of the building unit on the upper floor and the outer wall of the building unit on the lower floor with the long decorative material, and the gap becomes invisible.

When the long decorative material is pushed downward,
If the protrusions protruding on both sides of the locking claws of the fixture are inserted until they are located above the holding portion of the long decorative material, the long decorative material is hard to come off due to the protrusions. Therefore, the long decorative material is firmly attached to the outer wall, which is preferable.
