Abstract:

PURPOSE: To improve balance and prevent vibration of a shaft by providing the plural number of cylinders in the peripheral direction so as to be shifted from one another, while each cylinder is corresponding to each of the plural number of eccentric parts separated by an about equal angle in the peripheral direction of the shaft.

CONSTITUTION: In the space where a shaft 12 is positioned in a cylinder block 11, two circular eccentric parts 15a, 15b are arranged in the peripheral direction of the shaft 12 separately by an equal angle. On the other hand, in the spaces corresponding to the eccentric parts 15a, 15b of the cylinder block 11, the plural number of cylindes 20a, 20b are radially provided.
