れる。Next, a method of manufacturing the lower arm of the present invention will be described. Before the lower arm member 1a constituting the lower arm 1 and the lower arm member 1b constituting the lower arm 1 are joined, they are formed as shown in FIG. An unfoamed rubber 5a having a volume ratio of about 1/5 with respect to the cavity 4 is loaded in the cavity 4 and the two members 1a and 1b are joined and welded by CO 2 welding. After that, when the lower arm 1 is heated at about 150 ° C. for about 20 minutes, the unfoamed rubber 5a expands and expands to fill the entire cavity 4 as shown in FIG. 1, and the metal of the lower arm members 1a and 1b is filled. The inside of the cavity 4 is filled so that the surface is not exposed. The lower arm 1
Of course, rust-proof coating is also applied to the surface, and the lower arm is manufactured.
