Claims

[Scope of utility model registration request]

In a grease bath mounting structure that seals between the lower surface of the revolution frame on the swing side of a vehicle having an upper rotating body such as a power shovel and the top of a grease bath provided in the swing circle on the traveling side, An elevating member that can maintain a flange provided at the lower end of the side part in a predetermined gap state from a state in which it is in contact with a bottom cover below the flange, and an elevating member that is inserted between the flange and the bottom cover to prevent interference with the elevating member. A plurality of arc-shaped spacers that have a notch on the outside to prevent the spacer from forming and become substantially annular when installed, and a tightening member that holds the spacers between the flange and the bottom cover and integrates the three. Prepare,
A mounting structure for a grease bath that facilitates seal replacement, characterized in that by removing the spacer, the flange comes into contact with the bottom cover and the seal of the grease bath can be lowered from the lower surface of the Revo frame.
