1. A mover comprising:
a body;
an axle provided for the body;
a drive wheel arranged rotatably around the axle;
a motor;
a speed reducer attached to the axle and configured to reduce rotational power of the motor and transmit reduced rotational power of the motor; and
a shaft coupling configured to transmit the rotational power of the speed reducer to the drive wheel,
the speed reducer including an output shaft aligned with a center axis of the axle,
the shaft coupling including a cylindrical portion, the cylindrical portion having an annular shape when viewed along the center axis and housing the speed reducer at least partially inside,
the cylindrical portion including:
an input portion forming one part, located at a first end along the center axis, of the cylindrical portion, the input portion being configured to receive the rotational power from the output shaft;
an output portion forming another part, located at a second end along the center axis, of the cylindrical portion, the output portion being configured to output the rotational power to the drive wheel; and
an absorber provided between the input portion and the output portion, the absorber being configured to absorb deviation and an angle of deviation between a rotational center axis of the output shaft and a rotational center axis of the drive wheel.
