Abstract: Provided is a fiber reinforced plastic member made by a braiding technique to obtain high rigidity and superior vibration damping performance under a bending load. A reinforcing member made of carbon fiber reinforced plastic resin extends in a specific direction along an axis of the reinforcing member and includes a carbon fiber braided structure. The carbon fiber braided structure has a structure in which a plurality of axial yarns, a plurality of first braid yarns, and a plurality of second braid yarns are braided. A plurality of first braid yarns are wound to intersect the axis at a first braid angle. A plurality of second braid yarns are wound to intersect the axis at a second braid angle. The first braid yarns and the second braid yarns intersect each other.
