PURPOSE:To protect a twin belt unloader for unloading goods from a ship's hold from snaking so that its stable continuous operation can be performed by providing flanges on both lug-part rollers of a twin belt conveyor in such a manner that a lateral movement of the belt is regulated by the flanges. CONSTITUTION:On both lateral sides of belts 3, 4 are placed respective pairs of carrying rollers 55, and then, the lug-parts of the belts 3, 4 are pressed from their front and rear alternatively by the roller parts 56a of lug-part rollers 56. In addition, on the mounting part side of the lug-part rollers 56 to the right above frames 2 are formed flanges 56b respectively in such a manner that both sides of each of the belts 3, 4 come in contact with each of the flanges 56b. Thereby, the lateral movement of the belts 3, 4 is regulated so that the snaking of belts can be prevented from taking place, and consequently, the twin belt unloader can be operated continuously under a stable condition over a long period of time.
