<P>PROBLEM TO BE SOLVED: To provide an opening/closing device for a tank capable of easily enhancing sealing property of a pouring port and excellent in operability at oil feeding. <P>SOLUTION: A cap mechanism 20 is mounted to an opening of an inlet pipe 10. In the cap mechanism 20, a cap body 30 is non-removably and rotatably mounted to the inlet pipe 10. The cap body 30 has a pouring port 32b and is opened/closed by an opening/closing member 52. When a handle 43 is rotated/operated, the cap body 30 is ascended while rotated. A link mechanism 60 is mounted to the opening/closing member 52. The link mechanism 60 is rotatable relative to the inlet pipe 10, however, since movement is restricted in an axial direction, the opening/closing member 52 is opened/closed by lifting of the cap body 30. <P>COPYRIGHT: (C)2007,JPO&INPIT |
