<P>PROBLEM TO BE SOLVED: To provide a movable cover lid capable of maintaining mobility even when the distance between wheels changes due to deformation of a cover lid body, which has been not been conventionally solved. <P>SOLUTION: A movable cover lid 1 comprises a small-sized cover lid body 2 which covers and closes an opening 51 formed on top of a water tank 50, and a wheel 7 which allows the small-sized cover lid body 2 to be moved. The small-sized cover lid body 2 comprises a couple of small-sized split lid bodies 10 and 11, and a connection member 12. Each of the small-sized split lid bodies 10 and 11 are connected to each other to allow for relative rotation through the connection member 12. The small-sized split lid bodies 10 and 11 are inclined such that the connection member 12 is located above the opening 51 when the small-sized cover lid body 2 covers the water tank 50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
