A hydraulic tubing support that reduces noise transmitted to an operator due to pulsation of hydraulic oil in a junction tube. The hydraulic tubing support structure includes a pair of left and right remote control valves for generating pilot pressures for the plurality of hydraulic actuators in response to an input operation performed on each operating lever, pump-side tubes and tank-side tubes respectively extending from the respective remote control valves, a junction tube for allowing communication of the tubes guided to below a floor plate through a through hole and communication of the tubes guided to below the floor plate through a through hole, and a middle reinforcement beam extending in a right-and-left direction and fixed to the lower surface of the floor plate. The junction tube is fixed to the middle reinforcement beam in a non-contact state with the floor plate.
