Zusammenfassung:	PURPOSE:To eliminate a connecting flange of a vessel, to reduce a manufacturing cost of the vessel and to improve hermetical sealability, durability by applying a laser beam welding in assembling of the vessel at portions requiring no internal inspection. CONSTITUTION:A flange is not provided at the end of a vessel 1 of a bus. Vessels are connected by a laser beam welding. Thus, a flange member is not required, wide precise cutting of the flange, drilling of a connecting bolt hole are eliminated. An O-ring replacing work is obviated to improve corrosion resistance of the vessel.
