ABSTRACT:
A torque limiter limits transmission of torque between a drive shaft and an output shaft. The torque limiter includes a first rotational plate connected to the drive shaft, a second rotational plate facing the first rotational shaft and connected to the output shaft to be movable along an axial direction thereof, a ball ramp portion provided between the first rotational plate and the second rotational plate, a ball retained in the ball ramp portion, and a spring portion for pressing between the first rotational plate and the second rotational plate. A ball channel is formed in at least one of the first rotational plate and the second rotational plate. The ball in the ball ramp portion falls in the ball channel when the torque between the drive shaft and the output shaft exceeds a predetermined value to shut off the transmission of the torque.
