The invention provides a tank closing structure. The purpose of the present invention is to alleviate stress concentration due to swelling deformation of a cover member. The tank closing structure comprises a tank main body (12) for storing liquid, a cover member (18) for closing an opening part (16) formed in the tank main body (12) and having liquid swelling property, and a retaining ring (40) for retaining a flange part (18b) of the cover member (18) on the tank main body (12). The tank closing structure is provided with a deformation promoting portion for promoting deformation in which the center portion in the radial direction is recessed toward the inside of the tank main body (12) due to swelling of the flange portion (18b) of the cover member (18). The deformation promoting section is an inclined surface (53) that is formed on an opposing surface of the retaining ring (40) that faces the outer peripheral section of the cover member (18) and that is inclined in a direction that gradually separates from the cover member (18) from the inside toward the outside in the radial direction.
本发明提供一种箱的封闭构造。缓和由盖构件的溶胀变形导致的应力集中。箱的封闭构造包括储存液体的箱主体(12)、封闭在箱主体(12)形成的开口部(16)且具有液体溶胀性的盖构件(18)、将盖构件(18)的凸缘部(18b)保持于箱主体(12)的保持环(40)。该箱的封闭构造包括变形促进部,该变形促进部用于促进因盖构件(18)的凸缘部(18b)的溶胀而径向上的中央部朝向箱主体(12)内侧凹陷的变形。变形促进部为倾斜面(53),该倾斜面(53)形成于保持环(40)的与盖构件(18)的外周部相对的相对面且随着自径向内侧朝向外侧去而向自盖构件(18)逐渐分开的方向倾斜。
