立に際して非常に手間が掛り面倒であつた。 For example, when a tractor or the like is equipped with a hydraulic system at the rear of the vehicle, when the work equipment is attached to perform tillage work, the lifting and lowering of the work equipment is adjusted by the hydraulic system. The hydraulic piping from the work machine was connected to an auxiliary hydraulic pressure extraction device attached to the hydraulic system for lifting and lowering the work machine. However, in the case where the hydraulic system of the tractor body is covered with a floor sheet from above and surrounded on both sides by rear wheel fenders, the hydraulic piping on the work machine side is connected to the auxiliary hydraulic pressure extraction device. Therefore, it is difficult to do this by extending the hydraulic pressure extraction piping from the auxiliary hydraulic pressure extraction device to the vicinity of the rear end of the floor seat, and installing a unique bracket etc. to support the end of the piping. The ends were supported, and the bracket was fixed to the vehicle body with bolts or the like. However, this increases production costs and is extremely time-consuming and troublesome to assemble.
