SPRUE BUSH AND BUSH COMPONENT THEREOF

A sprue bush that is attached to a mold used to mold synthetic resin includes: a sprue bush main body (10) that has a flow passage, through which synthetic resin injected from an injection molding nozzle flows, and a recessed portion (13) formed in a surface of the sprue bush main body on a synthetic resin injection port side thereof; and a bush component (20) that is embedded in the recessed portion (13), the bush component (20) including: a nozzle contact surface (21) that is contacted by the injection molding nozzle; a through hole (22) that extends from an opening in the nozzle contact surface (21) and communicates with the flow passage in the sprue bush main body so as to form the flow passage for the synthetic resin; and a plurality of ribs (23) that extend radially outward from an inner peripheral surface of the through hole.
