る。When the center drive gear 8 is turned to the left by the motor 7 via an arbitrary power transmission mechanism, the left gear 17 mounted on the left shaft 16 engaged with the center drive gear 8 turns to the right. Since the left gear 17 and the boss 19 have an integral structure, the boss 19 also turns right. The oscillating left gear 18 supported by the boss 19 of the left gear 17 has an elastic portion 2
Since the second gear 2 is elastically attached to the boss 19, the oscillating left gear 18 rotates rightward together with the boss 19 by the frictional force between the elastic portion 22 and the boss 19. When the oscillating left gear 18 rotates clockwise, the oscillating left gear 18 meshes with the left fixed gear 24 fixed to the fixing portion 3, so that the oscillating left gear 18 resists the elasticity of the center return spring 31. The oscillating body 1 is turned to the left around the axis 2, and FIG.
As shown in FIG. 3, the left gear 17 is lowered to mesh with the passive gear 25. When the left side gear 17 meshes with the passive gear 25, the rocking body 1 cannot rotate further to the left and stops, and the passive gear 25 engages with the left side gear 17 that rotates right while the motor 7 continues to rotate. Turn left if necessary. When the center drive gear 8 is turned to the left by the motor 7, the motor 7 and the passive gear 25 are connected to each other, and the passive gear 25 also rotates to the left.

動歯車２５も右回転する。Conversely, when the central drive gear 8 is rotated clockwise by the motor 7 via an arbitrary power transmission mechanism, the right gear 10 which is axially mounted on the right shaft 9 engaged with the central drive gear 8 becomes Since the right gear 10 and the boss 12 have an integral structure, the boss 12 also turns left. Since the swing right gear 11 supported by the boss 12 has the elastic portion 14 elastically attached to the boss 12 by the elastic force of the spring 13, the swing right gear 11 is formed by the frictional force between the elastic portion 14 and the boss 12. Turn left with boss 12. When the oscillating right gear 11 rotates to the left, the oscillating right gear 11 meshes with the right fixed gear 23 fixed to the fixing portion 3, so that the oscillating right gear 11 resists the elasticity of the center return spring 31. The oscillating body 1 is rotated rightward about the shaft 2, the right gear 10 is lowered, and meshes with the passive gear 25. When the right gear 10 meshes with the passive gear 25, the rocking body 1 stops rotating without being able to turn clockwise any more, and the passive gear 25 engages with the right gear 10 that rotates left while the motor 7 continues to rotate. Turn right if necessary. When the central drive gear 8 is rotated clockwise by the motor 7, the motor 7 and the passive gear 25 are connected, and the passive gear 25 also rotates clockwise.

When the energization of the motor 7 is stopped, the oscillating body 1 returns to the center by the elastic force of the center return spring 31, the right gear 10 or the left gear 17 is separated from the passive gear 25, and the connection state between the motor 7 and the passive gear 25 is changed. It is released. That is, the motor 7
When the rotation of the central drive gear 8 and the gear meshing with the central drive gear 8 are stopped by turning off the power, the force for swinging the rocking body 1 about the shaft 2 disappears, and the elasticity of the center return spring 31 is reduced. 1 is returned to the neutral position in FIG.
Alternatively, the left gear 17 is separated from the passive gear 25, and the connection between the motor 7 and the passive gear 25 is released. in this way,
When both the left and right gears 10 and 17 are disengaged from the passive gear 25, the passive gear 25 becomes idle alone, so that when the passive gear 25 is manually rotated, the resistance is small and the passive gear 25 can be easily rotated. it can. This mechanism is
For example, the present invention can be applied to an automatic opening and closing sliding door of an automobile. In this case, when the passive gear 25 is connected to the sliding door and the motor 7 is rotated, the sliding door opens or closes depending on the rotation direction. When the motor 7 is stopped, even if the sliding door is manually opened or closed, only the passive gear 25 is rotated, and the subsequent mechanism on the motor 7 side is not moved. It can be opened and closed with low resistance.

Bosses 12 and 19 are provided which project from the right gear 10 and the left gear 17 to the side than the right gear 10 and the left gear 17. The oscillating right gear 11 and the oscillating left gear are provided on the outer periphery of the bosses 12 and 19. 18 are fitted to the oscillating right gear 11 and the oscillating left gear 18 to the bosses 12 and 19, respectively.
Since it has a configuration in which the elastic portions 14 and 22 for elastically impacting are provided, the swing right gear 11 and the swing left gear 18 can be easily impacted. The present invention also provides an oscillator 1 formed of a central upper arm 4, a right arm 5, and a left arm 6, which rotates about the shaft 2 with the elasticity of a center return spring 31 and returns to the center, and 2
A central drive gear 8 attached by a shaft 2a on the same axis as the central drive gear 8 and rotated forward and reverse by a forward / reverse rotation motor 7, and a central drive gear 8 axially mounted on the right arm 5 of the oscillating body 1 with a shaft 9; The right gear 10 meshing with the left arm 6 of the rocking body 1 is pivotally mounted on the shaft 16 with a shaft 16 and meshes with the central drive gear 8, and the outer periphery of the boss 12 of the right gear 10 is resilient by a spring 13. The oscillating right gear 11 and the left gear 17 that are fitted so as to be elastically engaged and co-rotate with each other are fitted so as to elastically fit with the spring 21 and are co-rotated with the outer periphery of the boss 19 of the left gear 17 by frictional force. The right swing gear 18 and the right fixed gear 23 provided on the side of the swing right gear 11 and engaged with the swing right gear 11 and the swing provided on the side of the swing left gear 18. Left fixed gear 24 with which left gear 18 is engaged
A right gear 10 and a left gear 17 which are provided below the right fixed gear 23 and the left fixed gear 24 and are engaged alternately against the elasticity of the center return spring 31; When the energization of the motor 7 is stopped, the oscillating body 1 returns to the center by the elastic force of the center return spring 31 so that one of the left and right gears 10 and 17 engaged with the passive gear 25 becomes the passive gear. 25
Since the rotation power forward / reverse device is more detachable, the above-described effects can be expected, and implementation is easy.
