PURPOSE:To make improvements in rigidity, by constituting a textile bundle of a covered layer rolled aslant so as to be crossed between spoke holes on a core material, in case of the above-captioned rim covering the metal core material with a fiber-plastic compound layer. CONSTITUTION:A first fiber-plastic compound layer 31 is formed in a core material A forming spoke holes 2 at the adjacent area inclusive of these spoke holes 2 in parallel with a rim cross section. Next, a second fiber-plastic compound layer 32 is formed on the former as being rolled on so as to make the strip textile bundles 10 and 10 slant and to be crossed between these spoke holes 2. With this constitution, textile distribution inside a covered layer B becomes uniformized over a rim as a whole, thus improvement in its rigidity is promoted.
