Abstract

PURPOSE: To reduce the size and to simplify the structure by pressing the braking member against the buffering member through the axial thrust produced when a plurality of intermediate rotary member for performing the transmission to the drum coupled to the load is rotating.
CONSTITUTION: When lowering the load the armature 12, the shaft 13 and the first helical gear 13a rotates clockwise when looking from the commutator side, while the second and third helical gears 27, 24 rotate counterclockwise and the fourth and fifth helical gears 31, 42 rotate clockwise. Since the axial thrust due to the second helical gear 27 is smaller than that due to the third helical gear 24, the combined thrust against the armature axis functions to the right. Said combined thrust presses the braking member 37 through the brake pad against the buffering member 44. While since the shaft 13 is coupled with the braking member 37 through the engaging means 38, the braking member 37 rotates together with the shaft 13 while pressed against the buffering member 44.
