a tank main body that stores a liquid material; a cover body that covers an opening of the tank main body; a support body that is positioned opposite to the cover body; a seal body that is sandwiched by a flange provided at the opening end of the tank main body and the cover body; and tightening members that tighten the cover body and the support body, and is capable of, even when the thickness of the flange provided at the opening end of the tank main body is thin, attaching the cover body on the flange while maintaining a contact property. ## Claims ### Claim 1 A storage tank comprising: a tank main body that is made of metal and stores a storage object consisting of at least any one or both of liquid and a solid; a cover body that covers an opening of the tank main body; a support body that has a ring shape and is positioned opposite to the cover body; and a tightening member that tightens the cover body and the support body, wherein the tank main body is provided with a flange at an opening end thereof, and the cover body and the support body are tightened by the tightening member in a state of sandwiching the flange. ### Claim 2 (depends on 1) The storage tank according to claim 1, wherein the cover body and the support body are tightened by the tightening member on an outer side than an outer edge of the flange. ### Claim 3 (depends on 2) The storage tank according to claim 2, wherein the tightening member protrudes from the outer side than the outer edge of the flange in any one of the cover body and the support body, the other of the cover body and the support body is provided with a hole to be inserted with the tightening member, and the cover body and the support body are tightened by tightening of the tightening member into the hole. ### Claim 4 (depends on 1) The storage tank according to claim 1, further comprising a seal body that is sandwiched by the cover body and the flange. ### Claim 5 (depends on 4) The storage tank according to claim 4, further comprising a spacer that is sandwiched by the cover body and the support body, wherein the spacer is thicker than a thickness of the flange, and thinner than a thickness obtained by adding a thickness of the seal body in a non-pressurized state to the thickness of the flange. ### Claim 6 (depends on 4) The storage tank according to claim 4, wherein the cover body has a holding groove in a surface opposite to the flange, the holding groove holding the seal body. ### Claim 7 (depends on 1) The storage tank according to claim 1, wherein the tank main body is integrally shaped. ### Claim 8 (depends on 1) A material vaporization device comprising the storage tank according to claim 1, the material vaporization device comprising: a heater that heats the storage object stored in the tank main body; a lead-out pipe that is provided to the cover body to lead gas produced by vaporizing the storage object out of the tank main body; and a flow rate control device that is connected to the lead-out pipe. ### Claim 9 (depends on 1) A liquid material supply device comprising the storage tank according to claim 1, the liquid material supply device comprising a lead out pipe that is provided to the cover body to lead the storage object consisting of liquid out of the tank main body. ### Claim 10 (depends on 1) The storage tank according to claim 1, wherein the support body is formed as one ring. ### Claim 11 (depends on 1) The storage tank according to claim 1, wherein the support body is formed from a plurality of parts.
