る。FIG. 5 shows that the rotary plate 19 is rotated counterclockwise as a moving body, and the pin 16 is moved through the tilting body 21 as a supporting member.
The center 16c of the center of the oscillating body 4 to the bisector C of the turning radii A and B
The positional relationship of each member when brought up is shown. FIG. 5 is geometrically inevitably obtained with reference to FIG. When the center 16c of the pin 16 comes to the bisector C, the movement of the fulcrum (pin 16) due to the swing of the swing body 4 is minimized. And, the pin 16 has the center 5 of the support shaft 5.
An attempt is made to move the illustrated small movement amount δ in the axial direction connecting c and the center 16c of the pin 16. On the other hand, since the pin 16 is swung by the tilting body 21 about the fixed tilting center 21c, the direction is the direction of the chain line D. Therefore, a slight displacement of the center 16c of the pin 16 in this direction causes the rotating body 3 provided with the one-side clutch to swing in the direction of the chain line D. That is, the oscillator 4
The swing range of is clearly shown by the results shown in FIG. 1 and by the dotted lines. Then, as shown in the figure, the link 11 is substantially linear on one end side of the swing range. In this state, since there is no center bending of the link, the movement of the oscillating body 4 is directly transmitted to the pin 13, and the amount by which the pin 13 rotates the rotating body 3 having the one-way clutch becomes maximum.
図中26はケースである。In the figure, 26 is a case.
