Reference numeral 64 denotes a transport path of the transport vehicle, and a pair of rails 65 for the transport vehicle are laid on the transport path 64 along both sides thereof. Numerals 66 denote parking sections formed in a row along both sides of the transport path 64, and a pair of traversing rails 68 is laid on a base 67 of the parking sections 66. Reference numeral 69 denotes a tray for automatic on-vehicle mounting, which has a bogie structure as a whole, and has a total of eight wheels 690 on each of four front and rear portions. The tray lock mechanism 70 used here includes a stopper pin 71 provided on the front side or the rear side of the tray 69 and a parking section 66.
Locking device 72 provided on the front side or the rear side of
1 and a lock release device 77 provided on the front side or the rear side.

The stopper pin 71 of the tray 69 is disposed on the tray 69 on the inner side extension of the axis of the wheel 690 located on the side of the transport path 64, and is attached to the axis via bolts or the like (not shown). . Lock device 7
Reference numeral 2 denotes a box-shaped shaft holding portion 73, which is disposed in the shaft holding portion 73 so as to be able to advance and retreat between the transport path 64 and the parking section 66, and is normally urged toward the transport path 64 by a spring means (not shown). Driven shaft 74, which takes a fixed position, a movable hook 75 linked to the driven shaft 74, and a movable hook 75 formed at a fixed position of the driven shaft 74 at the shaft holding portion 73.
The movable hook 75 is tilted by displacing the driven shaft 74 from the fixed position to the retracted position with respect to the transport path 64 by tilting the movable hook 75 and the locked position where the stopper pin 71 of the tray 69 is engaged. A hook guide 76 for guiding rotation between an unlock position for releasing engagement with the stopper pin 71; The lock device 72 is fixed at a predetermined position on the base 67 in each parking section 66.
