Claims

[Claims for Utility Model Registration] (1) A speed reducer built into a drive system that drives a load such as a water gate, an electric motor connected to the input shaft of the speed reducer via a first electromagnetic clutch, and a second motor connected to the input shaft. a screw brake connected via an electromagnetic clutch; a switching means for switching on/off states of the first electromagnetic clutch and the second electromagnetic clutch; a manual rotation shaft connected to the screw brake; and a manual rotation shaft provided for the manual rotation shaft. A load drive transmission device with a screw brake, comprising a mechanical load device with a screw brake, and a manual handle attached to the manual rotating shaft. (2) The screw brake includes a nut having a gear that meshes with the manual rotation shaft, a male-threaded rotation shaft that meshes with the nut, and a disk boss that is arranged on both sides of the nut and rotates integrally with the male-threaded rotation shaft. Each ratchet wheel is disposed between the nut and the disc boss via a friction disc, and is locked to one of the ratchet wheels to restrict forward rotation of the ratchet wheel. 2. A load drive transmission device with a screw brake according to claim 1, comprising a ratchet for forward rotation and a ratchet for reverse rotation that is locked to the other ratchet wheel to restrict rotation of said ratchet wheel in the opposite direction.
