Abstract:
A valve gate of an injection valve includes a center pin whose end portion is exposed to a cavity, a valve main body accommodating the center pin, a valve tip surrounding an outer circumferential portion of the end portion of the center pin and fixed at an inner circumferential portion of the valve main body, a sleeve pin provided so as to be slidable along the center pin, a reservoir portion formed between the valve main body and the sleeve pin and accommodating a molten resin, and a heater surrounding the reservoir portion, wherein the sleeve pin is displaceable between a position where an opened state is established and a position where a closed state is established, and an end portion of the heater facing the cavity is positioned closer to the cavity than an end portion of the reservoir portion facing the cavity when the closed state is established.
