(to) supports the rotation axis so that it can rotate freely. On the outside of the bracket (), a primary shaft α◆ is provided integrally with the shaft, and a slip ring Q is attached to its outer periphery via an electrically insulating cylinder (2). In addition, a wheel (2) is attached to the next shaft o4#ζ via a one-way latch 4 whose main parts are an inner ring 0*, an outer ring (c), and a pawl os, and the wheel (2) is attached to a guide rail. (5) It is designed to roll on top. - A flywheel (2) having an appropriate G is attached to the leading edge of the next axis α◆. In addition, an identifier core (2) wound with a stator coil (2) having an appropriate Cζ winding 8 is attached to the inner periphery of the frame (8), and the stator coil 4 and slip rig 4 are connected to an appropriate Cζ winding 8. They are electrically coupled in a certain way. Stator core (2
) is fixed on the rotating shaft by an appropriate method corresponding to the inner periphery of the rotor core. A wheel (2) is attached to one of the rotating shafts via a one-way latch 4, and is adapted to roll on a guide rail (6). The one-way clutches 4 and - are assembled so that their rotational transmission directions are opposite to each other. Cylindrical container (3
) A plurality of current collecting overhead wires are provided between both ends of the slip ring via a suitable insulator, and each is attached so as to be in pressure contact with the slip ring. Therefore stator coil cap ζ
The generated electric power is led to the outside via the slip ring and the collector mw. In addition, a flywheel with an appropriate GD2 is fixed to the tip of the one-rotation shaft (2).
Ru.

In the device configured as described above, when the floating body (1) moves up and down due to waves, the cradle opening (1) performs a tilting movement due to the wavelength of the waves, and as a result, the cylindrical container (1)
3) also performs a tilting motion from side to side, and due to the tilting motion of the 4-cylindrical container (8), the wheels 4 and tl) roll in the same direction on the guide rail. At this time, the rotation axis and the identifier frame (8) rotate in opposite directions due to the action of one-way clutches H attached to the respective wheels R and H. That is, as shown in the layer ζ of FIG.
When 1 (2) rotates in the direction of arrow A -ζ, the wheel hook, (2)
One-way clutch (rotation) fixed to the inner circumference of (2)
The outer ring os also rotates, and the pawl (2) engages with the inner ring (b), causing the frame (8) or the rotating shaft (2) to rotate in the same direction of the arrow A' via the inner ring (b). In addition, a flywheel with an excessive GD" and a flywheel are provided at the tip of the frame (8) and the tip at the time of rotation, respectively, and the one-way clutches 90.m have rotation transmission directions opposite to each other. Because it is assembled so that
The stator frame (8) and the rotating shaft (2) have ξs that are opposite to each other. Also, due to the action of the flywheel (2), once the frame 2) or the rotation 1lIIoa starts to rotate, the rotation continues and always tries to rotate in the same direction. As shown in Fig. 4, when @ stops or reverses from the state shown in Fig. 8 in the direction of arrow 1, the grip of the pawl shaft between the outer ring (2) and the inner ring (2) is Off.

The inner ring (b) is directed in the same direction as shown in diagram M8, that is, arrow A'
Continue rotating in the same direction.

The wheels (2) and the wheels are respectively the guide rails (&) tt@
At the @ part, the impact is absorbed by the backing plate (7) and the buffer member (6), and it is also biased in the opposite direction, so forward and reverse rotations are repeated smoothly.

As mentioned above, the vertical movement of a floating field due to waves can be controlled by a cylindrical container (
3) is converted into a repeated tilting motion, and the left and right rolling of the wheels (2) and @ caused by this tilting motion is converted into mutual forward and reverse rotation of the stator frame (8) one rotation through a one-sided clutch. The present invention provides a power generation device in which the relative rotational speed of the rotor core with respect to the stator is doubled and electric power is efficiently obtained.
