An axial member (73) supports the first eccentric cam (71) and the second eccentric cam (72).

An oscillation cam is mounted to the eccentric cam.

A drive shaft with an eccentric cam, is rotatably received in the cylinder block and a cam bearing extend around the eccentric cam.

The eccentric cam is held stationary with respect to the crankpin when the crankshaft is rotating in the forward direction.

There is a spring disposed between the internal cam and external cam so as to form an eccentric cam mechanism.

One of an eccentric cam (6) and an adapting.plate (8) that form an eccentric pin mechanism is connected to the input shaft (3).

A displacement mechanism of a secondary transfer unit (40) includes a first eccentric cam (71), a second eccentric cam (72) and an axial member (73).

The actuator (20) is descended when a peripheral portion of the eccentric cam (31) more distanced from a center of the eccentric cam is in contact with the roll ring (24) to push the roll ring.

An eccentric ring or cam to adjust the position of the apex of the conical disk relative to an insole by rotating the eccentric ring or cam.

In the film pressing system, a roll ring (24) and an eccentric cam (31) are mounted on a side of the actuator (20), and a rotation shaft (32) is integrated with the eccentric cam.

An eccentric cam is attached to a handle mounted on the valve stem.

The lever (25) is provided with an eccentric cam portion (59) and a handle portion (61).

An effort to extract the card (2) from the insertion port (3) results in the eccentric cam (10) being further rotated by the friction force between the card (2) and the eccentric cam (10).

In the clamp, an eccentric cam may rotate around an axis parallel with the rod axis.

The eccentric cam rotates with respect to the crankpin when the crankshaft is rotating in the reverse direction.
