PROBLEM TO BE SOLVED: To save the space, to improve the workability, and to prevent the heat generation. SOLUTION: A high-pressure hose 5 for oil is connected to an oil pump, and a pulse wave damping device formed of a straight pipeline 10 having a diameter larger than that of the high-pressure hose 5, a first taper pipeline 11, which is integrally connected to one side of the straight pipeline 10 and of which diameter is gradually enlarged, as it comes close to the straight pipeline 10, and a second taper pipeline 12, which is integrally connected to the other side of the straight pipeline 10 and of which diameter is gradually reduced, as it is separated from the straight pipeline 10, is interposed at a desirable position of the high-pressure hose 5. Pulse wave of the oil is thereby attenuated. |
