[0029] Hereinafter, an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0030] As shown in FIGS. 4 and 5, a rear spoiler 100 of the present disclosure includes fixing units 400, which are mounted to a left side and a right side of a muffler 200, and locking units 300, which are formed at a left side a the right side of a spoiler body 110 and are locked to the fixing units 400.

[0031] Each of the locking units 300 is formed at a corresponding lateral side of the spoiler body 110 and includes an elastic support portion 310, which has a fixing hook 311 formed above the lateral side of the spoiler body 110 and a bolt hole 312 formed below the fixing hook 311.

[0032] In particular, the elastic support portion 310 is formed integrally with a respective one of the left side and the right side of the spoiler body 110, and the fixing hook 311 protrudes from the upper end portion of the elastic support portion 310.

[0033] Further, the bolt hole 312 is formed in the lower portion of the elastic support portion 310.

[0034] In addition, the spoiler body 110 has a curved protruding portion 111, which extends in the longitudinal direction of the muffler.

[0035] The curved protruding portion 111 is oriented in the outward direction from the muffler and is located at the lower portion of the muffler.

[0036] The above-described curved protruding portion 111, which extends in the longitudinal direction of the muffler, reduces flow loss at the rear end of the lateral-installation-type muffler, thereby improving straightness of airflow under the vehicle.

[0037] In addition, as shown in FIGS. 6A-6B, the elastic support portion 310, which is formed at a respective one of the left side and the right side of the spoiler body 110, has elastic force, by which the gap from the bracket is minimized.

[0038] Referring to FIG. 6A (RELATED ART), a conventional rear spoiler has a shortcoming in that the bracket is relatively large in order to ensure fastening area for two bolts, which are fastened to the bracket on each lateral side of the spoiler body of the conventional rear spoiler. In order to solve this problem, as shown in FIG. 6B, the present disclosure employs a single fixing hook 311, which is elastically deformable, and a single coupling bolt 430 at each lateral side of the spoiler body, thereby minimizing the size of the bracket and improving assembly efficiency.

[0039] In addition, each of the fixing units 400, as shown in FIG. 8, includes a bracket 410 mounted to the muffler, a first hole 411a formed in the upper portion of the bracket 410 for passage of the fixing hook 311 therethrough, a second hole 411b, in which the fixing hook 311 is fitted after passing through the first hole 411a, a bolt hole 412, which is formed below the first and second holes 411a and 411b, and a bolt 420, which is fastened into the bolt hole 412 formed in the bracket 410 via the bolt hole 312 formed in the elastic support portion 310 in order to securely mount the rear spoiler to the muffler.

[0040] The first and second holes 411a and 411b are formed in the shape of a long slot.

[0041] Accordingly, the rear spoiler for a muffler, having the above construction, is installed as shown in FIG. 7.

[0042] First, the fixing hook 311 of the fixing unit 300, which is formed at a respective one of the left side and the right side of the spoiler body 110, passes through the first hole 411a formed in the bracket 410 and is temporarily fitted into the second hole 411b.

[0043] Subsequently, the bolt hole 312, which is formed in the installation surface (the surface of the lower portion of the elastic support portion 310) of the rear spoiler, is aligned with the bolt hole 412 formed in the bracket 410.

[0044] Subsequently, as shown in FIG. 8, the bolt 420 is fastened into the bolt hole 412, which is formed in the bracket 410, via the bolt hole 312 formed in the installation surface of the rear spoiler.

[0045] In addition, referring to an enlarged view showing the coupling structure of the fixing hook 311 in FIG. 8, the fixing hook 311 has a locking groove 311a, which is formed long in the longitudinal direction of the fixing hook 311, whereby the fixing hook 311 is more securely fitted into the second hole 411b formed in the bracket 410.

[0046] As is apparent from the above description, a rear spoiler for a muffler according to the present disclosure has the following effects.

[0047] First, the structure of the rear spoiler is made robust yet simple by eliminating a conventional bracket for reinforcing rigidity and by minimizing the number of bolts for fixing the rear spoiler to a muffler. Accordingly, the quality of the product is improved, increases in manufacturing costs and weight thereof are minimized, and the improvement in fuel efficiency is maximized.

[0048] Second, in order to remedy the shortcoming of a conventional rear spoiler, in which a bracket is relatively large in order to ensure fastening area for two bolts, which are fastened to the bracket on each lateral side of a spoiler body, the present disclosure employs a single fixing hook, which is elastically deformable, and a single coupling bolt at each lateral side of a spoiler body, thereby reducing the number of bolts (from four to two), minimizing the size of the bracket, and improving assembly efficiency.

[0049] Third, in order to remedy the shortcoming of a conventional rear spoiler having a cantilever structure, in which the distance from the coupling position of the upper end of the spoiler to the lower end thereof and the size of the spoiler are large, in which a reinforcement member is added, and in which adjustment of the gap between the muffler and the end of the spoiler is difficult, the present disclosure provides a compact structure in which the spoiler is fixed to the muffler merely by fastening a bolt only to the lower end portion of the spoiler body and the bracket, whereby the size of the upper end portion of the spoiler body is minimized, a reinforcement member is not required, and adjustment of the gap between the muffler and the end of the spoiler is easy.

[0050] Although the preferred embodiment of the present disclosure has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications can be made without departing from the scope and spirit of the disclosure.

[0051] Therefore, the scope of the disclosure should be limited only by the accompanying claims and equivalents thereof. In other words, it should be understood that these embodiments are given by way of illustration only and do not limit the scope of the present disclosure, and that various modifications, additions and substitutions can be made without departing from the spirit and scope of the disclosure defined only by the accompanying claims and equivalents thereof.
