PROBLEM TO BE SOLVED: To provide a structure which facilitates attachment/detachment of a hydraulic oil tank upper cover for detachably covering a front upper portion of a hydraulic oil tank, that forms the housing of an upper revolving body of a construction machine. SOLUTION: The hydraulic oil tank upper cover 10 has one of insertion pins 13 and receiving portions into which the insertion pins are fitted, and one of a slot piece 15 having a U-shaped groove extending in the same direction as that of the insertion pins, and a hook pin 25 for being fitted into the U-shaped groove. On the other hand, a building cover onto which the hydraulic oil tank upper cover 10 is fitted, has the other one of the the receiving portions into which the insertion pins 13 are fitted, and the insertion pins fitted into the receiving portions, and the other one of the hook pin 25 inserted into the U-shaped groove formed in the slot piece, by vibration occurring when the insertion pins are inserted into the receiving portions, and the slot piece 15 having the U-shaped groove into which the hook pin is inserted, at respective corresponding locations. Thus the hydraulic oil tank cover 10 can be attached/detached without bolts. COPYRIGHT: (C)2007,JPO&INPIT
