Abstract:
A tubular motor may include a tubular case, a motor unit provided inside the case, and a first planetary gear unit placed inside the case at an output side in the motor shaft direction with respect to the motor unit. On the motor unit, a concave part may be formed in an output side end surface of an output side end plate section that supports a rotor, at an output side of the rotor. On the first planetary gear unit, a planetary carrier may include a supporting plate that overlaps with planetary gears at an counter-output side in order to support the planetary gears from the counter-output side. The first planetary gear unit may be immediately adjacent to the output side end plate section at an output side.
