Even if a member made of glass is brought into contact with a corner of a continuous portion of the conveyance surface, the parcel can be reliably conveyed while being shaken. Therefore, when transporting a liquid or a bottle containing a liquid and a solid or the like inside, the liquid or the like is transported while being shaken in the bottle, that is, while being agitated inside the bottle. The load can be made uniform and the load on the rollers can be conveyed in a predetermined time.

Further, since a hollow portion is provided inside the polygonal roller to form a cylindrical shape, and a through hole penetrating from the conveying surface to the hollow portion is formed, a conveyor using the roller is formed. When placed in a steam room and passed through the above-mentioned bottle, etc., the air flow by the steam also circulates inside the roller itself, and the bottle always hits the warm air by the steam,
Therefore, the temperature of the liquid in the bottle can be efficiently raised.

Further, the roller is composed of a roller unit and a connecting means, a connecting convex portion is provided at one end of the roller unit, and a connecting concave portion shaped to engage with the connecting convex portion is provided at the other end of the roller unit. It is possible to adjust the total length of the roller because it is provided at the same time or because the joint collar that connects the conveying members in series is provided. Therefore, it has various advantages such that it can be used for any roller conveyor having a different width depending on the size of the transported goods.
