A cryogenic container for the natural gas of a vehicle is provided to maintain internal pressure stably and prevent breakage even if some of cryogenic liquid is changed into gas by flowing the vaporized gas into a space corresponding to the different height between the upper side of an inner wall of a main storage part and a spray nozzle of a liquid supply line and a space of an auxiliary storage part. The cryogenic container for the natural gas of a vehicle is composed of: a main storage part(10) forming a vacuum space between an inner wall(11) and an outer wall(12) and storing cryogenic liquid; an auxiliary storage part(20) installed adjacently to the upper side of the inner wall of the main storage part; a liquid supply line(30) installed with penetrating through the inside of the main storage part from the outside to feed the cryogenic liquid into the main storage part; a venturi connecting pipe(40) having a vertical venturi port formed inside to vertically communicate with the lower side of the auxiliary storage part and horizontal venturi ports formed at both sides facing each other to communicate with the vertical venture port, and mixing and transferring the liquid and gas of the auxiliary storage part to the liquid supply line in feeding the cryogenic liquid to the liquid supply line, by connecting the liquid supply line to each horizontal venturi port; and a line combining unit(70) combined through the main storage part while integrally surrounding parts penetrating through the inside of the main storage part of a discharge line(50) and the liquid supply line so as to cut off heat from being transferred from the outside to the main storage part.
