The rotary driving means has a rotary shaft.

A left rotating shaft and a right rotating shaft are installed on the cylinder block.

A device for damping runout vibration of a rotating shaft system at least including a rotating shaft and a rotating body rotatably supported by the shaft.

Said rotatable shaft (16) can be driven by a rotational drive.

The first state is a state wherein the rotational force of the second rotary shaft can be transmitted to the first rotary shaft and the rotational force of the first rotary shaft cannot be transmitted to the second rotary shaft.

Each group of the push component (5) comprises a first rotating shaft (51) and a second rotating shaft (52).

The rotary shaft is a hollow rotary shaft provided with a through hole.

The tank supports a rotatable shaft.

The second shaft has an aperture therein and is axially co-aligned with the first shaft and is rotatably mounted adjacent the rotatable first shaft.

The member is attached to a rotating shaft.

The driving unit is provided with a spindle (210), and the spindle runs through the spindle hole.

The spindle member defines a longitudinal axis and includes a second flange provided on an end of the spindle member and a follower member provided on an opposite end of the spindle member.

A waved channel (18) receiving a flexible rotatable shaft (16) is located in the condom wall plane.

An end of a rotating shaft (9) is connected to a rotating arm (10).

Each of the rotating bodies has a flexibility so that a rotating shaft can be bent.
