As shown in FIGS. 1 and 2, the tank 1 of the present embodiment includes a tank body 2 for storing compressed air or the like, and a support structure 3 for supporting the tank body 2.

[0010] The support structure 3 of the tank 1 includes an annular support base 4 fixed to the bottom surface 2a of the tank body 2, and at least three, in this embodiment three, legs 5 extending radially outward from the support base 4. Such a support structure 3 of the tank 1 can be stably installed by the support base 4 and at least three legs 5 even if the bottom surface 2a of the tank body 2 is a curved surface.

[0011] FIG. 3 is a partially enlarged bottom view of the support structure 3, and FIG. 4 is a partially enlarged side view of the support structure 3. As shown in FIGS. 2 to 4, the leg portion 5 of the present embodiment has a fixing portion 6 for fixing to the installation position of the tank 1 and a lower surface support portion 7 that contacts the lower surface 4a of the support base 4.

[0012] In such a support structure 3 of the tank 1, since the lower surface 4a of the support base 4 does not contact the installation position, even when the installation position is not flat, the tank 1 can be installed at the installation position by leveling only the portion where the leg portion 5 contacts. For this reason, the support structure 3 of the tank 1 of the present embodiment can be stably installed regardless of the installation position.

[0013] As a more preferable aspect, the tank 1 is an air tank for holding compressed air. The compressed air is preferably generated by a compressor (not shown). The tank 1 is not limited to such an aspect and may store various gases and liquids.
