The fitting portion of the chain fitting 250 fixed to the endless chain 240 wound around the pair of sprockets 230 that are guided to move freely and rotated is connected to the fitted portion 226 of the attachment 220 to the circulation movement line K. Since the fitting is performed so as to be relatively movable in the orthogonal direction, the transfer distance of the pallet 100 does not vary regardless of the extension of the endless chain 240.
Further, since the protrusions or holes of the chain fitting 250 are fitted to the holes or protrusions of the attachment 220 so as to be relatively movable with respect to the direction perpendicular to the circulation movement line K, the pallet 100 can be used regardless of the extension of the endless chain 240. The transfer distance does not change.
Further, since the rotating roller of the attachment 220 rolls in turn between the guide surface of the linear guide portion 212 and the guide surface of the semicircular guide portion 213, the attachment 220 is smoothly guided by the guide mechanism 210, and is endless. Regardless of the elongation of the chain 240, the transfer distance of the pallet 100 does not change.
In addition, when the attachment 220 is guided by the linear guide portion 212, one first rotating roller 223a and two second rotating rollers 223b of the attachment 220 are turned to each other across a pair of linear guide surfaces. When the attachment 220 is guided by the semicircular arc guide part 213, one first rotary roller 223a and one third rotary roller 223c of the attachment 220 sandwich a pair of semicircular arc guide surfaces. Since each of them rolls, the attachment 220 is guided by the endless guide part and can move smoothly along the circulation movement line K, and the transfer distance of the pallet 100 varies regardless of the extension of the endless chain 240. do not do.
Further, when viewed from above, the circular movement line K can be virtualized, the horizontal movement restriction guide part 211h restricts the movement in the horizontal direction perpendicular to the circulation movement line K of the attachment 220, and the vertical movement restriction guide part 211v becomes the attachment 220. The movement in the vertical direction perpendicular to the circulation movement line K is restricted, and the roll restriction guide portion 211r restricts the roll around the circulation movement line of the attachment 220. Therefore, the attachment is guided to the endless guide portion. Thus, the transfer distance of the pallet 100 does not vary regardless of the extension of the endless chain 240.

Moreover, the parking apparatus concerning embodiment of this invention has the following effects by the structure.
The engagement portion 222 of the attachment 220 is engaged with the engaged portion 120 of the pallet 100, and the attachment 220 is connected to the guide portion 211 in which a pair of linear guide portions 212 and a pair of semicircular guide portions 213 are connected.

A plurality of pallets 100 that are fitted so as to be movable relative to each other in a direction orthogonal to the pallet, and the pallets 100 are mounted along the transfer path by the pallet feed mechanism 200, and the pallet orthogonal feed mechanism 300 Since the pallet 100 is fed in the orthogonal direction and the vehicle is parked in the parking space, the endless chain 240 may be extended. It does not change the transfer distance of the pallet 100, the pallet 100 for mounting the vehicle to move in the transport direction and perpendicular direction to park the vehicle in the parking space.
Further, since the protrusions or holes of the chain fitting 250 are fitted to the holes or protrusions of the attachment 220 so as to be relatively movable with respect to the direction perpendicular to the circulation movement line K, the pallet 100 can be used regardless of the extension of the endless chain 240. The pallet 100 is guided and moved without changing the transfer distance.
Further, since the rotating roller of the attachment 220 rolls in turn between the guide surface of the linear guide portion 212 and the guide surface of the semicircular guide portion 213, the attachment 220 is smoothly guided by the guide mechanism 210, and is endless. Regardless of the elongation of the chain 240, the transfer distance of the pallet 100 does not change, and the pallet 100 is guided and moved.
In addition, when the attachment 220 is guided by the linear guide portion 212, one first rotating roller 223a and two second rotating rollers 223b of the attachment 220 are turned to each other across a pair of linear guide surfaces. When the attachment 220 is guided by the semicircular arc guide part 213, one first rotary roller 223a and one third rotary roller 223c of the attachment 220 sandwich a pair of semicircular arc guide surfaces. Since the rollers 220 roll to each other, the attachment 220 is guided by the endless guide portion 211 and can smoothly move along the circulation movement line K, and the transfer distance of the pallet 100 can be increased regardless of the extension of the endless chain 240. The pallet 100 is moved stably without fluctuation.
Further, when viewed from above, the circular movement line K can be virtualized, the horizontal movement restriction guide part 211h restricts the movement in the horizontal direction perpendicular to the circulation movement line K of the attachment 220, and the vertical movement restriction guide part 211v becomes the attachment 220. Since the movement in the vertical direction perpendicular to the circulation movement line is restricted and the roll restriction guide portion 211r restricts the roll around the circulation movement line K of the attachment 220, the attachment 220 guides to the endless guide portion. Thus, the pallet 100 can move smoothly along the circulation line, and the pallet 100 can be moved stably without changing the transfer distance of the pallet 100 regardless of the elongation of the endless chain 240.
