PROBLEM TO BE SOLVED: To provide a tank excellent in quality of a welding part, hardly causing stress concentration and clearance corrosion, and excellent in durability.SOLUTION: In a tank T, among a pair of mutually corresponding opening peripheral edge parts 10 and 20 of a body member 1 and an end plate 2, one opening peripheral edge part 20 has an inclined cylindrical part 21 of becoming small in an outer diameter toward the tip side, and the opening peripheral edge parts 10 and 20 are welded in a state of inserting this inclined cylindrical part 21 inside the other opening peripheral edge part 10, and a clearance 3 is formed between an outer peripheral surface 21a of the inclined cylindrical part 21 and an inner peripheral surface 10a of the other opening peripheral edge part 10. A wall surface part 40 by a welding bead part 4 exists in the innermost part of the clearance 3, and two corner parts C1 and C2 connected by crossing with the wall surface part 40, are formed in a state of mutually separating the outer peripheral surface 21a and the inner peripheral surface 10a in a radial direction of the body member 1. |
