SPRUE BUSH AND BUSH PART THEREOF

Provided is a new sprue bush capable of preventing stringiness. The sprue bush attached to a mold for molding synthetic resin is provided with: a sprue bush body (10) having a flow path for the synthetic resin injected from an injection molding nozzle and having a concave part (13) on a surface thereof on a side where the synthetic resin is to be poured; and a bush part (20) embedded in the concave part (13). The bush part (20) has a nozzle contact surface (21) where the injection molding nozzle contacts, a through-hole (22) extending from an opening of the nozzle contact surface (21) and communicating with a flow path of the spur bush body to form the flow path for the synthetic resin, and a plurality of ribs (23) extending radially from an inner peripheral surface of the through-hole to an outside.
