Abstract
PURPOSE:To obtain a secure coupling condition of a coupler for linking two vehicles to each other by providing a detector detecting the existence of a coupling bar of the vehicle inserted between guides of reception member and operating a coupling hook by the said detector output. CONSTITUTION:A tractor and a trailer comes closer to each other, and a coupling bar 41 of the trailer enters between guides 3a and 3b of a reception member 3 of the trailer, then a detector 21 is pushed, and a conductor bar 24 is also pushed toward the direction of a mounting shaft 43. Therefore a working piece 28 operates to make a switch 29 on through a lever 30, then detection signal is output. This signal makes off the electric conduction to a solenoid 11, then a rocking piece 12 comes back to a solid line position and a coupling hook 5 is also swung back to its solid line position by a spring 6. Consequently the perpendicular part 41s of the coupling bar 41 is enclosed by means of guides 3a, 3b of the reception member 3 and the top end of the coupling hook 5, resultantly to complete to couple the tractor and trailer.
