<p>PURPOSE:To disuse a guide rail any longer as well as to relieve an impact when a car rides onto a conveyor, by providing a pusher dog body with a weight, while causing the pusher dog body to fall and rise with its dead load. CONSTITUTION:In the case where a self-propelling car 4 gets onto a conveyor 1 with its left wheels 4a and 4b, when the car rides on a pusher dog 14 being projected from the surface of a slat 2 by means of a weight 16 whose center of gravity is positioned rearward from a fixed shaft 8, a central part 14b is pushed by a left front wheel 4a or a left rear wheel 4b so that a body 15 rotates and moves forward centering on the fixed shaft 8 and falls down and thereby the central part 14b comes to be flush with the slat 2. At this time, a rear part 14c hits a rear stopper 17b and its rotating motion is checked, so that the central part 14b may be kept in being flush with the surface of the slat 2.</p> |
