Claims

[Scope of utility model registration request]

an arm plate provided on the seat back side and having fan-shaped teeth; a base plate on which this arm plate is supported rotatably and provided on the seat cushion side; A lock disk having a tooth portion formed on a part of its outer periphery to mesh with the fan-shaped tooth portion, and a lock disk provided on an eccentric shaft portion of a shaft member that pivotally supports the lock disk and formed on one side of the lock disk. a transmission gear that meshes with an internal toothed portion in a circular hole; a helical gear that is rotatably held by a holder bracket that is provided on a shaft member coaxially with the lock disc and assembled on the base plate side; A worm is rotatably held on the holder bracket so as to mesh with the helical gear and is rotationally driven by an external drive source, and the rotation of the worm is transmitted to the helical gear at a reduced speed, and The transmission gear rotates integrally with the arm plate and is transmitted to the lock disc at a reduced speed by the internal teeth, and the rotation of the lock disc is transmitted to the arm plate by the meshing of the teeth on its outer periphery with the fan-shaped teeth. A reclining device characterized by being configured to transmit deceleration to the side.
