Device for extending the axis of a motor, which being designed to extend the axis of a motor by its terminal portion protruding through at least one of the ends of such a motor and such a device incorporating an extension element that integrates a blind cavity centered in axial direction where the terminal portion of the motor shaft is coaxially adjusted; It is characterized because: - The terminal portion (3') of the motor shaft (3) (4) incorporates a first centered axial bore (7) located in correspondence with the front base (11) of such terminal portion (3'); - The bottom (2') of the blind cavity (2) of the extension element (1) incorporates a second centered axial bore (8) facing the first centered axial bore (7); - Both centered axial perforations, first (7) and second (8), are related by means of an anchoring element that immobilizes at least the relative rotation in one direction of the extension element (1) with respect to the axis (3) of the motor (4) and also immobilizes the extension element (1) in the axial direction.
