Zusammenfassung:In order to achieve a configuration for a motor unit for a wave gear speed reducer wherein the motor unit can be attached to the wave gear speed reducer in a compact manner, this motor unit for a wave gear speed reducer is equipped with: a rotary shaft extending in the axial line direction; a rotor unit that rotates integrally with the rotary shaft; a stator unit arranged opposing the rotor unit; and a motor casing to which the stator unit is secured. The motor casing has a second cover that covers the rotor unit and the stator unit from the other side in the axial line direction. The rotary shaft extends toward the other side in the axial line direction, penetrates the second cover, and is connected to a cam. The second cover has a support part that extends toward the other side in the axial line direction, supports the rotary shaft in a rotatable manner, and is positioned on the inside of an external gear when a wave gear speed reducer is attached to the motor casing.
