It cannot be said to be excellent, and it is inferior in disassembly and assemblability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and an object of the present invention is to make it possible to easily attach a slat to a slat support mechanism, to provide excellent disassembly and assemblability, and to manufacture and maintain the apparatus. The present invention is to provide a mounting device for mounting a blade plate of a blind shutter to a blade plate support mechanism, which can perform the above operation in a short time and which can be aesthetically excellent.

[0005]

According to the present invention, it is an object of the present invention to provide a semi-cylindrical first fitting space extending in the longitudinal direction on the back surface of a blade plate and communicating the first fitting space to the outside. A first hollow portion formed with a first slit extending in the longitudinal direction, a second fitting space extending in the longitudinal direction on the back surface of the blade plate, and the second fitting space communicating with the outside to extend in the longitudinal direction. Mounting means for mounting a blade plate of a blind shutter having a second hollow portion formed with a second slit extending to a blade plate support mechanism, the blade shutter being inserted into one end into a first fitting space. A fitting that is free and has a fitting portion fitted into the first fitting space and extends through the first slit; and one end of which is freely insertable into the second fitting space. And a fitting portion fitted into the second fitting space,
And a clamp that extends at the other end and clamps the other end of the fixture between the back surface of the blade and the other end of the fixture. This is achieved by a mounting device in which a mounting portion for mounting on a vehicle is formed.

[0006] In a preferred example, the fitting portion of the mounting tool is integrally formed with a projection to be fitted into a notch formed in the first hollow portion of the blade plate. When the fitting is engaged with the notch, the lateral movement of the attachment can be prevented, so that the blade plate can be more firmly supported.
At this time, in order to absorb the expansion and contraction of the thermal expansion of the wing plate, at one end of the wing plate, a cutout of the first hollow portion and a projection of the fitting portion of the mounting tool are not provided. It may be relatively slidable. The outer shape of the first hollow portion is not particularly required to be semicircular, but the first hollow portion is formed integrally with the semicylindrical portion and the locking plate extending inward from the semicylindrical portion. When it is formed to have a portion, a blade having a shape excellent in appearance can be obtained.

Further, when a recess is formed in the fixture and a projection that engages with the recess is formed integrally with the other end of the clamp, the other end of the fixture by the clamp can be stably maintained. It can be effectively prevented that only one of the clamp and the fixture is moved in the lateral direction and the clamp on the other end of the fixture is released. Note that the recess may be provided on the holding tool and the projection may be provided on the mounting tool. When a rotating mechanism for rotating the blade plate for lighting is provided in the blade plate supporting mechanism, an arm may be formed on the mounting portion, and this arm may be connected to the rotating mechanism.
