To solve such problems that a device is complicated and expensive and is used only in a snow season even though a method of dragging a carriage forcibly or attaching a sled to a lower part of the carriage is taken since wheels are buried in snow and do not rotate when conveying cargoes with the carriage with wheels on snow in a conventional technique, and snow adheres to the sled and the carriage and is brought into a room.SOLUTION: There is provided a multipurpose conveyance tray which has a bottom plate, a front wall plate and a side wall plate in such a manner that can be easily attached/detached even on snow and on a normal ground surface, prevents snow accretion on a carriage and can be used for multi-purposes through the year, in which grip parts are oriented in the oblong shape in the front wall plate and both side wall plates in the winnowing basket shape whose rear end is opened, a semicircular column-shaped reinforcement member is equipped toward the upper side of the front wall plate outer surface from the rear side of the bottom plate lower surface, the upper peripheral edges of both side wall plates from the front wall plate are caught in the outer side as a cylindrical reinforcement material for reinforcement, and an opening of the bottom plate rear end is reinforced to be thick, and these components are integrally molded with metal or synthetic resin.SELECTED DRAWING: Figure 1 【課題】従来、積雪上を車輪の付いた台車で荷物を運搬するときは、車輪が雪中に埋まって回転しないため強引に台車を引きずるか台車の下部にソリを装着する方法が取られていたが、装置も複雑で高価であり、積雪時期のみの使用であった。また、ソリや台車に雪が付着して室内に持ち込むことも課題であった。【解決手段】そこで、積雪上でも通常地面でも容易に着脱が出来、台車にも着雪させることなく、かつ、通年多目的に使用できるように、底板、前壁板、側壁板を設け、後端を開口した箕状の形状で、前壁板と両側壁板に把持部を長円形に向け、底板下面の後方から前壁板外面の上方に向けて半円柱状補強部材を装備し、前壁板から両側壁板の上周縁は補強のために円筒状補強材として外側に巻き込み、底板後端の開口部を肉厚で補強して、これらを金属製か合成樹脂で一体成形した多目的運搬トレーとした。【選択図】図１
