Abstract
To manufacture a steering wheel rim, a sleeve 21 is formed by a braiding machine 12 by interlacing and braiding unidirectional fibers 10. A coil-shaped lightweight core 9 is then inserted by a covering apparatus 14 into the braided sleeve, and core rings are cut out from the coil. The ends of the cut rings are butted to form the rims, and after being joined with a spoke 2 are placed in a mold 31, where an outer molded layer 11 is formed by injecting a thermosetting resin into the mold and heat curing it.
