- Guide portions 114 formed with concave guide grooves 114a for guiding linear movement of the movable member 130 in the other side portions 112b and 113b of the first and second extension portions 112 and 113. are attached to each other. That is, the guide portion 114 is integrally attached to the distal edges of the other side portions 112b and 113b of the first and second extension portions 112 and 113 by welding or the like. Referring to FIG. 9, two guide grooves 114a are formed in the guide portion 114 of the fixing member 110 disposed to support the central portion of the movable member 130, while both of the movable members 130 are formed. It can be seen that one guide groove 114a is formed in the guide portion 114 of the fixing member 110a disposed to support the end portion.
- the movable member 130 has a shape that can be arranged in the corner portion of the storage tank (10).
- the cross-sectional shape of the movable member 130 may be formed similarly to the cross-sectional shape of the fixing part 111 of the fixing member 110 described above.
