To provide an apparatus for filling an object to be packaged into a bag with a high density.

In order to put an object to be packaged into a bag while adjusting the directional property of the object, this bagging machine is designed to move the bag suspended by a clamp along an endless track together with the clamp and house the object in the bag in the moving course. In this machine, when an impact blow is given to a hammering core 13 with a rotary cam 18, a channel-shaped member 10 slidably supported by a sleeve 17 with the aid of a guide member 14 is vibrated in a lateral direction to shake the bag 26 suspended by the clamp 25. An object to be packaged such as, for example, flaked dried-bonito in the bag is settled flat by the lateral shaking of the bag and can be packaged in reduced bulk. Two balance springs 20, 21 for keeping the neutrality of the channel-shaped member 10 give an aftereffect to the vibration of the channel-shaped member 10 even after the rotation of the cam 18 is stopped, and adjust the uniform directional property of the object.
