PROBLEM TO BE SOLVED: To have a support plate sufficiently deformed so as to prevent any stress concentration on a welded place between the support plate and a sub-tank, by forming a step part for separating the bottom wall upward in relation to the support plate on the side end edge of a sub-tank along the protruding part of the support plate. SOLUTION: A part of bottom wall 21 is bent to be separated upward in relation to a support plate 3 on both end edge part in the length direction of the bottom wall 21 in a sub-tank 2 opposite to the protruding part 31 of the support plate 3. By means of each step part 23, the support plate 3 can be deformed on the step part 23 forming internal end side provided on the bottom wall 21 of the sub-tank 2 across a range from oppositely contact part position toward the support plate 3 to a spot welded part S2 toward a tank main body 1 of each protruding part 31. Accordingly, even if the bottom wall 11 of the tank main body 1 is actuated severely owing to the vibration, etc., during running of a vehicle, the support plate 3 can be deformed sufficiently in response to actuation so that stress concentration in a spot weld part S1 between the support plate 3 and the sub-tank 2 can be prevented.
