The transfer apparatus includes a hot feed material storage device, a hot feed material transfer line, device for unblocking the hot feed material transfer line and a pressurising device. Thus, even if injection start timing changes in accordance with a change in an operating state and if the pump pressure-feeding quantity supplied during the injection period changes because of the change in the injection start timing, variation in the actual injection quantity can be inhibited. The first body has a support surface opposed to the articulating surface.
