PROBLEM TO BE SOLVED: To provide a joint fixer in construction machinery, which is made of a small number of components and reliably prevents a joint from coming off from piping. SOLUTION: The joint fixer in construction machinery prevents a joint 30 provided at the connections of hydraulic piping to feed pressure oil from coming off from pipes 27, 28. The joint fixer comprises: a main component 35a provided along pipes 27, 28 connected together with the joint 30; a stopper 35b protruding to and coming into contact with an end of the main component 35a to prevent the joint 30 from coming off from either the pipe 27 or 28; and a fixer fitting part 35d removably installed on a fitting seat 37 (provided at the other end of the main component 35a and on the pipe 27 or 28) with a fitting means 36. By this joint fixer, the freedom of pipes 27, 28 is largely increased and, the design and construction of hydraulic piping are made easier. The joint fixer is made of a small number of parts, and consequently entire piping work costs are reduced. COPYRIGHT: (C)2007,JPO&INPIT
