Claim of US Patent No. 10,245,944

1. A tank mounted on a working vehicle comprising:an exterior member including:
a first plate unit;
a second plate unit continuing to one end of the first plate unit;
a third plate unit continuing to the other end of the first plate unit and opposed to the second plate unit with a gap therebetween;
a fourth plate unit joined to an end of the second plate unit and an end of the third plate unit and opposed to the first plate unit with a gap therebetween;
a fifth plate unit continuing to one end of the fourth plate unit and joined to the first plate unit, the second plate unit, and the third plate unit; and
a sixth plate unit continuing to the other end of the fourth plate unit, joined to the first plate unit, the second plate unit, and the third plate unit, and opposed to the fifth plate unit with a gap therebetween, the exterior member including an inner space defined by a first inner surface of the first plate unit, a second inner surface of the second plate unit, a third inner surface of the third plate unit, a fourth inner surface of the fourth plate unit, a fifth inner surface of the fifth plate unit, and a sixth inner surface of the sixth plate unit;
a first baffle plate joined to the first inner surface, the second inner surface, and the third inner surface; and
a second baffle plate joined to the fourth inner surface, the fifth inner surface, and the sixth inner surface, wherein
a surface of the first baffle plate is orthogonal to the first inner surface, the second inner surface, and the third inner surface,
a surface of the second baffle plate is orthogonal to the fourth inner surface, the fifth inner surface, and the sixth inner surface,
the first baffle plate includes a first end face joined to the first inner surface, a second end face joined to the second inner surface, a third end face joined to the third inner surface, and a first opposed surface opposed to the second baffle plate,
the second baffle plate includes a fourth end face joined to the fourth inner surface, a fifth end face joined to the fifth inner surface, a sixth end face joined to the sixth inner surface, and a second opposed surface opposed to the first baffle plate,
a central portion of the first opposed surface is farther away from the fourth inner surface than both ends of the first opposed surface in a direction orthogonal to the fourth inner surface, and
a central portion of the second opposed surface is farther away from the first inner surface than both ends of the second opposed surface in a direction orthogonal to the first inner surface.
