PURPOSE:To automatically perform a feeding work of powdery material, by making a slider reciprocate so that a weighing chamber reciprocates between below a hopper and above a feed port. CONSTITUTION:After a feed port 3 is set to a manhole 8 or the like of a mixer 7, a slider 4 is moved with a drive cylinder 6 to bring a weighing chamber 5 below a hopper 2 so that powdery material in the hopper 2 drops into the weighing chamber 5 and a fixed amount thereof taken off. The slider 4 is moved with the drive cylinder 6 to bring the weighing chamber 5 above the feed port 3 together with the powdery material while a fixed amount of the powdery material in the weighing chamber 5 is automatically fed into the manhole 8 or the like from the feed port 3.
