The vibration of a cab deck as well as the mass of a deck supporting member is suppressed. A slewing frame of an upper slewing body includes a front plate connected to a second side plate. A cab deck is disposed on a front side of an engine deck with a gap between the cab deck and the engine deck. A deck supporting member is connected to the second side plate and the cab deck. When viewed along an up-and-down direction, a connection portion of the front plate to be connected to the second side plate is opposed to, in the lateral direction via the second side plate, a connection portion of the deck supporting member to be connected to the second side plate.

Upper slewing body

A cabin support deck for supporting a cabin of a construction machine on the underside of the cabin includes a frame member and a mounting portion. The frame member includes a proximal segment at which the frame member is supported, a distal segment, a left side segment, and a right side segment. The distal segment has a first structure having a first lateral dimension. The proximal segment has a second structure having a second lateral dimension which is greater than the first lateral dimension. At least one of the proximal side sections of the left side segment and the right side segment has the second structure, and the other portions of the left side segment and the right side segment have the first structure.
