いう優れた作用効果を奏するものである。At that time, the rotation of the third bevel gear 23 is controlled by the ratio of the number of teeth of the first gear 24 to the second gear 26 and the third gear 27 to the fourth gear 28 among the first gear 24 to the fourth gear 28. The rotation speed can be changed and transmitted to the 4-gear 28. Therefore, rotation is obtained from the output shaft 2 in the opposite direction to the rotation direction of the input shaft 1 and at a different rotation speed.
The electromagnetic clutch of the present invention uses bevel gears to reverse the rotation of the input shaft and transmit it to the output shaft, so there is no need for extra balls parallel to the input and output shafts or extra gears provided on these shafts. can be omitted, and the 2
An armature is provided on a holding member that holds a bevel gear meshing with two bevel gears so as to be rotatable around an output shaft, and a field core is provided at a position corresponding to the armature to prevent rotation of the holding member around the output shaft during reverse rotation. Since the rotation of the input shaft is transmitted to the output shaft, the space above the bevel gear can be effectively utilized, and the clutch as a whole can be made smaller, which is an excellent effect.

1. A forward-reversible electromagnetic clutch characterized by transmitting drive to a gear, a second gear, a third gear, and a fourth gear, with the direction of rotation of an output shaft being opposite to the direction of rotation of an input shaft.
