PROBLEM TO BE SOLVED: To provide a housing structure of light weight, low cost, so that its repair can be done simply and cheaply, by resolving a problem posed in a conventional constracting tool housing structure. SOLUTION: This housing structure in a hydraulic operation contract tool is provided with a housing having a hydraulic cylinder part 1b, in which a hydraulic piston for contraction of a contracting tool is installed, a grip part being installed in a manner for extending in a horizontal direction against the housing and, a hydraulic supply part 22 is installed in the grip part for supplying a hydraulic to the hydraulic cylinder part of the housing. The hydraulic cylinder part 1b of the housing is constituted in a separate element from the grip part 2, and the grip part 2 is divided into at least two parts 2b, 2c nearly along a face crossing the housing, and the hydraulic supply part 22 is constituted with a hydraulic conductive pipe 22, which is a separate element from the grip part 2. Under a status where one end of the hydraulic conducive pipe 22 is connected with the hydraulic cylinder part 1b in the housing, the divided portions 2b, 2c of the grip part 2 are arranged outside of the hydraulic conductive pipe 22 for coupling each other while they are coupled to the housing as well. |
