To provide a woody pellet type fuel combustion device capable of stably and quantitatively supplying the pellet at all times including a time when the combustion is turned down.

The pellet is taken out from a fuel accommodating part 5, and then the pellet 4 conveyed to an oblique upper part by the rotation of a fuel conveying member 37, is fed to a fuel discharging cylinder 38 side from a fuel discharge port 38a by the rotation of a partitioning plate 41. The pellet 4 can be surely fed to the fuel discharging cylinder 38 side from the fuel discharge port 38a by being controlled by a control member mounted at a downstream side of the fuel discharge port 38a even when the pellet is leaked to the fuel discharging cylinder 38 side, whereby the pellet 4 can be stably and quantitatively supplied at all times even when the combustion is turned down.
