DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a holding structure for holding a shaft portion of an automobile sun visor on an automobile ceiling wall via a holder.

[0002]

2. Description of the Related Art As a conventional holding structure of this kind, for example,
Japanese Unexamined Patent Application Publication No. 8-232922 discloses a technique. In the conventional holding structure, the shaft portion of the vehicle sun visor is held on the vehicle ceiling wall side via a synthetic resin holder, and the holder holds the shaft portion of the vehicle sun visor in a detachable manner. A base body integrally having a holding portion having a C-shaped cross section, and a hollow rectangular stem pushed into a mounting hole formed in a ceiling wall of an automobile is provided on a back surface of the base body. A pair of elastic claws engaging with the hole edge of the mounting hole are formed on the side surface through slits, and the free ends of the elastic claws are spaced apart from each other at a constant distance inward of the stem. The extension arm is connected to the base body, and an operation window for inserting a tool tip such as a flathead screwdriver is opened on the side of the base body.
The mounting hole formed in the ceiling wall of the automobile is a square hole similar to the rectangular shape of the stem.

Therefore, under the conventional holding structure, when the stem is pushed into a mounting hole formed in advance in the ceiling wall of the automobile, a pair of elastic claws engage with the hole edge of the mounting hole. ,
Since the base body is fixed to the vehicle ceiling wall with one touch, the shaft of the vehicle sun visor is then fitted into the holding portion of the base body, whereby the vehicle sun visor is turned toward the vehicle ceiling wall. It will be movably held.

On the contrary, when it becomes necessary to remove the holder from the ceiling wall of the automobile, a tool tip is inserted between the pair of release arms through the operation window, and the tips of the release arms are separated from each other. If this is done, the pair of elastic claws bend inward of the stem to release the engagement of the mounting hole with the hole rim. Thereafter, if the stem is pulled out of the mounting hole as it is, the holder is removed from the automobile ceiling wall. It can be removed.

[0005]

Therefore, in the conventional holding structure, it is not necessary to use a screw member for fixing the holder to the ceiling wall of the automobile, so that the fixing operation of the holder can be performed very easily. On the contrary, when removing the holder from the ceiling wall of a car, it is necessary to use a tool such as a flathead screwdriver. An operation window that allows insertion of the holder must be opened on the base body side, so that there is a sufficient risk that the appearance of the holder itself may be impaired.
