。[Claims for Utility Model Registration] (1) A piston is disposed in a cylinder so that it can reciprocate, and when pressurized oil is supplied to the chamber of the cylinder, the piston moves in the outward path and the processing jig at the tip of the piston is moved. After performing the prescribed machining, a flexible air bag is attached to the mounting member with an O-ring to prevent the generation of negative pressure in the chamber when the piston moves on its return path and returns to its initial position. However, in a portable hydraulic processing machine that is removably loosely inserted into a mounting hole communicating with a reservoir, the mounting member is configured to be separable by dividing the O-ring storage groove, and when the mounting member is assembled,
A portable hydraulic processing machine characterized in that a storage groove is formed in a shape having a wedge effect that pushes out an O-ring inside the storage groove radially outward. (2) The portable hydraulic processing machine according to claim 1, wherein the O-ring storage groove is formed in a substantially V-shaped cross section.
