Claims

[Scope of utility model registration request]

A timing belt that adjusts the tension of a timing belt that is wrapped around a crank sprocket of a crankshaft of an automobile engine and a cam sprocket of a camshaft, and is pressed by a tensioner to give a constant tension, and the fixing belt fixes the cam sprocket. a joint device connected to the crankshaft, a one-way clutch provided on the outer peripheral side of the joint device, a weight device that changes a weight that applies torque in the direction of engine rotation to the one-way clutch from a supported state to a free state, and a joint device. 1. An automatic timing belt weight method adjustment machine comprising: a motor connected to the device; and a pressing device that presses the tensioner against one side of the timing belt that has become slack due to the torque.
