Abstract

PURPOSE: To dispense with a conventional electromagnetic brake for a decelerated electric motor, simplify the construction of a transmission and reduce its size and weight, by enabling restraint of rotation of an output shaft when it has been rotated only in a prescribed direction.
CONSTITUTION: When the rotor shaft 3 of the motor is driven counterclockwise, a rotary member 5 is rotated clokwise throught a gear 3a. If an engagement means 5a made of female threads provided on the inside circuimferential surface of the rotary member 5 is twisted leftward, the member 5 is moved in the direction B pending its rotation because the engagement means 5a is engaged with another engagement means 7a made of male threads provided on the output shaft 7. The rotor is thus brought into pressural contact into with a spacer 11 on the major-diameter part 7C of the output shaft 7 to rotate it. When the rotor shaft 3 is driven clockwise, the rotary member 5 is moved in the direction A and brought into pressural contact with a brake plate 15 to rotate the output shaft 17 in the direction opposite to that of the preceding rotation.
