Description

Application of Article 30, Paragraph 2 of the Patent Law Tokai Design Co., Ltd. has applied the "hub cover" for patent applications on October 2, 2018, on the Internet shopping site Wowma! Published in. Also, as of October 18, 2018, the Internet auction site Yahoo! Auctions! It was exhibited in.

The present invention relates to a structure for attaching a hub cover to a vehicle, which is intended to decorate the vehicle.

Needless to say, when decorating a vehicle, there are various points in consideration of, for example, human preference, price, safety, and the like. Among them, as a simple and low-cost item and a part, there is a hub cover attached to an axle intended by the present invention. Therefore, various structures have been proposed for this type of hub cover mounting structure. For example, as a means for attaching the wheel cap to the hub, a locking projection and a positioning rib are formed on the wheel cap, and the wheel cap is attached to the locking peripheral groove of the wheel hub (invention of Japanese Patent Application Laid-Open No. 2001-71703). The invention of this document (1) is the mounting of a wheel cap, and there are problems in stability and / or structure in the structure (means) adopted for mounting because the products are different. As a similar invention, there is a structure in which a peripheral protrusion of a wheel cap and a positioning rib are fitted and pressed against a peripheral groove of a wheel hub and the upper surface of the opening thereof (invention of Japanese Patent Application Laid-Open No. 2001-71705). The invention of this document (2) has the same idea as the invention of the above-mentioned document (1), and has the same problem. In addition, it has a structure in which the tip of a wheel hub provided on the wheel is provided (invention of Japanese Square Root Extraction 3-1802). In the invention of this document (3), the hub cover cap is fitted to the wheel hub and its rotation is utilized to fix the hub cover cap by the concave-convex fitting locking. Therefore, as in the documents (1) and (2), the products are different and have the same problems.
