Abstract: a pneumatic tool includes a plastic tool body, a metal front hood connected to and disposed in front of the plastic tool body so as to define an accommodating space therebetween, and an air motor disposed within the accommodating space. The air motor includes a front bearing unit and a rear bearing unit disposed behind the front bearing unit. At least one of the front and rear bearing units is connected fixedly to the metal front hood. The air motor further includes a cylinder body disposed between the front and rear bearing units and connected integrally to the one of the front and rear bearing units, and a rotor disposed rotatably within the cylinder body.

Abstract: A transmission device includes a power output unit and a non-contact type sensing unit. The power output unit includes a power output member that is rotatable about an axis, and has at least one sensed portion that is co-rotatable with the power output member about the axis. The non-contact type sensing unit detects the sensed portion and generates a sensor output from which angular displacement and position of the power output member can be calculated.
