PROBLEM TO BE SOLVED: To provide a liquefied gas vaporization device capable of efficiently thawing frost adhering to a vaporization part in a short time. SOLUTION: This liquefied gas vaporization device is provided with the vaporization part 102 vaporizing liquefied gas and a heating part 104 heating gas vaporized at the vaporization part 102. The vaporization part 102 is provided with a heat transmission pipe 108 for vaporization and a vaporization part housing 106. An upper opening 114 and a lower opening 116 are provided at an upper end part and a lower end part of the vaporization part housing 106. An open close mechanism 156 is provided above the vaporization part housing 106, and opens and closes the upper opening 114 of the vaporization housing 106. Moreover, a heater for heating vaporized gas is provided. Liquefied gas is fed to the vaporization part 102 and the open close mechanism 156 is kept open during vaporization operation. Heated liquefied gas is fed to the vaporization part 102 and the open close mechanism 156 is kept close during thawing operation. COPYRIGHT: (C)2005,JPO&NCIPI
