ABSTRACT:
Disclosed is an air motor having an engine pack (with a rotor provided with front and rear retainers, a stator, and vanes) which can be assembled and replaced even by an unskilled person. An air supply joint is engaged with guide projections formed on the inner peripheral surface of a housing, with its forward end portion held in contact with the rear retainer; the forward end portion being fastened by a nut member which is threadedly engaged with the housing. On the rear face of the forward end portion are formed a plurality of first projections produced of a rigid synthetic resin, and on the front face of the nut member corresponding to the first projection are formed a plurality of second projections, so that a firm relation of engagement is established by an elastic force of restoration of the first projection; that is, the nut member will not accidentally become loose owing to the locking effect of the first and second projections. Furthermore, the engine pack can be drawn out straight by unfastening the nut member by a jig.
