Abstract
Abstract A reinforcing member includes a reinforcing resin layer which is elastic in its semi-hardened or unhardened state before the reinforcing member is applied to an object to be reinforced and which is rigid in its hardened state; an expandable member centered along the reinforcing resin layer; the expandable member being narrower than the reinforcing resin layer; the expandable member being elastic at least before the reinforcing member is applied to the object; the expandable member being expandable to form a bead-like projection before the reinforcing resin layer hardens; the reinforcing resin layer having its edge portions extending beyond the expandable member, the underside of the edge portions thereof being adapted to adhere to the object.
