[0002] 作為搬運重物之習知的台車，在貨台部的下面設置複數個自由腳輪且在貨台部的一側部設有把手(操作具)者是已知的(例如，專利文獻1)。 　　[0003] [專利文獻1]日本特開2015-107665號公報[0002] As a conventional trolley for carrying heavy objects, it is known that a plurality of free casters are provided under the cargo bed portion and a handle (operating tool) is provided on one side of the cargo bed portion (for example, Patent Literature 1).　　[0003] [Patent Document 1] JP 2015-107665 A

[發明所欲解決之問題] 　　[0004] 例如，被工作機械加工之金屬材料及加工後的工件，當重量較重，且必須頻繁進行裝載於台車及從台車卸載時，不僅工時(Man-hour)增加，且操作者的負擔也變大。 　　因此，必須儘可能地減少物品對台車的裝載及從台車的卸載。作為一個方法，將物品裝載於台車之後，儘可能將該物品在台車上進行保管的方法是可考慮的。 　　然而，習知的台車，因為當外力作用時容易造成移動，必須設置制動器等。此外，習知的台車，因為具備供操作者操作用的把手，在將多數的台車進行整理，還會有把手造成阻礙的問題。 　　[0005] 本發明是有鑑於上述問題點而開發完成的，其目的之一是為了提供一種台車，除了裝載物的移動以外還適用於裝載物的保管、保存，且也容易進行整理。 [解決問題之技術手段] 　　[0006] 本發明的第1觀點之台車，係具備台車主體、及可拆卸地連結於該台車主體之操作具， 　　前述台車主體係具備：支承移動對象物之貨台部、設置於前述貨台部的下面側之複數個車輪、以及具有與地面接觸的下端部且與前述複數個車輪協作而支承前述貨台部之支承部， 　　前述操作具係具備：操作桿部、及設置於前述操作桿部的下端側且形成為可與前述貨台部連結之提升部， 　　前述提升部係具有：在前述操作桿部的兩側設置成可旋轉自如之第1及第2車輪， 　　當要讓前述操作桿部連接於前述台車主體時， 　　是讓前述提升部的一部分卡止於前述貨台部的一部分， 　　一邊使作用於前述操作桿部之傾動轉矩以前述第1及第2車輪為支點作為將前述貨台部往上方推的力發揮作用，一邊使前述第1及第2車輪朝向前述貨台部側移動，藉此使前述台車主體的支承部從前述地面上昇， 　　藉由使前述提升部和前述台車主體的連結完成，讓前述複數個車輪及前述第1及第2車輪協作而將前述貨台部支承。 　　[0007] 本發明的第2觀點之台車，係具備台車主體、及可拆卸地連結於該台車主體之操作具， 　　前述台車主體係具備貨台部、複數個車輪及支承部， 　　前述貨台部是支承移動對象物， 　　前述複數個車輪，是支承前述貨台部，設置成以共通軸線為中心而可旋轉自如且在該共通軸線的方向上互相分離， 　　前述支承部，是具有與地面接觸的下端部，且與前述複數個車輪協作而支承前述貨台部， 　　前述操作具係具備操作桿部、及設置於前述操作桿部的下端側之提升部， 　　前述提升部係具備：在前述操作桿部的兩側設置成以沿與前述操作桿部的長度方向大致正交的方向延伸之軸線為中心而可旋轉自如之第1及第2車輪、以及可與設置於前述貨台部之被連結部連結之連結部， 　　當要使前述操作桿部連接於前述台車時，是以讓前述提升部之連結部位於前述貨台部之被連結部之下方的方式操作前述操作桿部的姿勢及操作具的位置， 　　接著，藉由前述操作桿部的傾動操作讓前述提升部的連結部卡止於前述貨台部的被連結部， 　　一邊使藉由操作而作用於前述操作桿部的傾動轉矩以前述第1及第2車輪為支點而作為將前述連結部所卡止之前述被連結部往上方推的力發揮作用，一邊使前述第1及第2車輪朝向前述被連結部的下方位置移動，藉此讓前述支承部從前述地面上昇， 　　藉由前述被連結部和前述連結部的連結完成，讓前述複數個車輪及前述第1及第2車輪協作而將前述貨台部支承。 　　[0008] 較佳為採用以下構成，即讓前述提升部的連結部可旋轉地連結於前述貨台部之被連結部，在讓兩者連結後的狀態下，藉由前述操作桿部的方向操作可將前述第1及第2車輪的方向操作自如。 　　更佳為採用以下構成，即前述提升部進一步具有限制部，在讓前述被連結部和前述連結部連結後的狀態下，藉由前述限制部與前述貨台部的一部分卡合而限制前述操作桿部的進一步傾動。 　　[0009] 此外亦可採用以下構成，即前述提升部進一步具有支承部，在讓前述操作具從前述台車主體卸下的狀態，為了維持讓前述操作桿部站立的狀態，前述支承部與前述第1及第2車輪協作而將前述操作桿部支承。 　　[0010] 本發明的操作具是使用於上述構成的台車。 　　[0011] 本發明的台車主體是使用於上述構成的台車。 [發明效果] 　　[0012] 依據本發明，因為台車主體具備可設置於地面之支承部，而提供還能適用於裝載物的保管、保存之台車。此外，因為能將台車主體和操作具分離，台車主體的整理也變容易。再者，依據本發明，還能大幅降低因地震所造成之裝載物倒塌的可能性。[Problem to be solved by the invention] 　　[0004] For example, when the weight of metal materials and processed workpieces processed by machine tools is heavy and must be frequently loaded on and unloaded from the trolley, not only man-hours (Man- The hour) increases, and the burden on the operator also increases.　　 Therefore, it is necessary to reduce the loading and unloading of items on the trolley as much as possible. As a method, after loading the articles on the trolley, it is conceivable to store the articles on the trolley as much as possible.　　 However, the conventional trolley, because it is easy to move when an external force acts, it is necessary to install a brake. In addition, since the conventional trolley has handles for the operator to operate, there is a problem that the handles will hinder the handling of most trolleys.　　[0005] The present invention was developed in view of the above-mentioned problems. One of its objectives is to provide a trolley that is suitable for storage and preservation of the load in addition to the movement of the load, and is also easy to organize. [Technical Means to Solve the Problem] 　　[0006] The trolley of the first aspect of the present invention is provided with a trolley body and an operating tool detachably connected to the trolley body, 　　 the above-mentioned trolley main system is equipped with a cargo platform that supports moving objects Part, a plurality of wheels arranged on the lower side of the cargo bed part, and a support part that has a lower end contacting the ground and supports the cargo bed part in cooperation with the plurality of wheels, 　　 the operating tool is provided with: an operating lever part , And provided on the lower end side of the operating lever portion and formed as a lifting portion that can be connected to the cargo bed portion, 　　 the lifting portion has: first and second rotatably provided on both sides of the operating lever portion The wheel, 　　 when the operating lever is to be connected to the trolley body, 　　 is to allow a part of the lifting part to be locked to a part of the cargo bed part, and 　　 while making the tilting torque acting on the operating lever to the first and The second wheel acts as a fulcrum as a force that pushes the cargo bed upward, and while moving the first and second wheels toward the cargo bed, the support part of the trolley body rises from the ground. By completing the connection of the lifting part and the trolley body, the plurality of wheels and the first and second wheels cooperate to support the cargo bed part. [0007] The trolley according to the second aspect of the present invention is provided with a trolley body and an operating tool detachably connected to the trolley body, 　　 the aforementioned trolley main system includes a cargo bed part, a plurality of wheels and a support part, and 　　 the aforementioned cargo bed part It supports the moving object, 　　 the plurality of wheels support the cargo bed, which is provided to be rotatable about a common axis and separated from each other in the direction of the common axis. The lower end part supports the cargo bed part in cooperation with the plurality of wheels, 　　 the operating tool is provided with an operating rod part and a lifting part provided on the lower end side of the operating rod part, and the lifting part is provided with: the operating rod Both sides of the part are provided with first and second wheels that are rotatable centered on an axis extending in a direction substantially orthogonal to the longitudinal direction of the operating lever part, and can be connected to the cargo bed part. The connecting part of the connecting part, 　　 when the operating rod part is to be connected to the trolley, the posture and operation of the operating rod part are operated in such a way that the connecting part of the lifting part is located below the connected part of the cargo bed part The position of the tool, 　　 Then, by the tilting operation of the operating lever portion, the connecting portion of the lifting portion is locked to the connected portion of the cargo bed portion, and the tilting torque acting on the operating lever portion by the operation The first and second wheels are used as fulcrums to act as a force for pushing upward the connected portion locked by the connecting portion, while moving the first and second wheels toward the lower position of the connected portion As a result, the support portion is raised from the ground, and the cargo bed portion is supported by the cooperation of the plurality of wheels and the first and second wheels by the completion of the connection between the connected portion and the connecting portion. [0008] Preferably, the following structure is adopted in which the connecting portion of the lifting portion is rotatably connected to the connected portion of the cargo bed portion, and in a state where the two are connected, the direction of the operating lever portion The direction of the aforementioned first and second wheels can be manipulated freely. It is more preferable to adopt a configuration in which the lifting portion further has a restricting portion, and in a state where the connected portion and the connecting portion are connected, the restricting portion engages with a part of the cargo bed portion to restrict the operation Further tilting of the rod. [0009] In addition, it is also possible to adopt a configuration in which the lifting portion further has a supporting portion, and in order to maintain the state in which the operating lever portion is allowed to stand in a state where the operating tool is detached from the trolley body, the supporting portion and the second The 1st and 2nd wheels cooperate to support the said operation rod part.　　[0010] The operating tool of the present invention is used for the trolley having the above-mentioned structure.　　[0011] The trolley body of the present invention is used for the trolley having the above-mentioned structure.

[0014] 以下，針對本發明的實施形態，參照圖式做說明。 　　圖1A~圖3顯示本發明的一實施形態之台車構造。圖中，L1，L2表示在與地面FL平行的水平面內之台車1的長度方向，M1，M2表示在該水平面內與台車1之長度方向L1，L2正交的橫方向。 　　台車1是由台車主體10、及可拆卸地連結於台車主體10之操作具30所構成。 　　[0015] 台車主體10，如圖2等所示般係具備：具有矩形外形之貨台部11、設置於貨台部11的下面11b之長度方向L1側的端部之2個車輪13A，13B(以下也稱為車輪13)、設置於貨台部11的下面11b之長度方向L2側的端部之2個支承部12A，12B(以下也稱為支承部12)、以及被連結部15 (以下也稱為被卡合部15)。 　　貨台部11，是用於裝載要搬運的物品，可以是由金屬材料等所形成的板材，也可以是由框架構件所組合而成。此外，除了板材及框架以外，也能採用金屬製的網籠作為貨台部，並在其下面設置車輪(腳輪)。不僅是重物，還能進行大容量物品的搬運、保持。 　　車輪13A，13B，是設置在貨台部11的下面11b之橫方向M1，M2的兩端部，成為以軸線K1中心而可旋轉自如，車輪13A，13B的方向是固定的。 　　[0016] 支承部12A，12B是由鋼材等所形成，是在貨台部11之下面11b之與車輪13A，13B側為相反側的端部，設置於橫方向M1，M2的兩端部。支承部12A，12B是讓下端面12b與地面FL接觸。在支承部12A，12B與地面FL接觸的狀態下，2個支承部12A，12B和2個車輪13A，13B協作而將貨台部11呈大致水平地保持，並支承來自貨台11的荷重。藉由使支承部12A，12B的下端面12b與地面FL接觸，貨台部11上所裝載的物品之重量越大，下端面12b和地面FL的摩擦力變得越大，而使台車主體10越不容易在地面FL上移動。 　　[0017] 被連結部15，是設置在2個支承部12A，12B間的大致中間位置，是由金屬製的圓筒構件所構成，係具有貫通孔15a，且其圓環狀的下端面15b是與後述的操作具30之連結部33卡合。被連結部15是藉由熔接而固定於貨台11的下面11b。 　　[0018] 操作具30，如圖3所示般係具備：呈直線狀延伸之操作桿部31、及設置於操作桿部31的下端部側之提升部32。 　　在操作桿部31的上端部，用於讓操作台車1的操作者把持之把手部31a是設置成沿與操作桿部31正交的方向水平地延伸。 　　[0019] 提升部32，是設置於操作桿部31的下端部，且具備有：形成於操作桿部31的下端部之連結部33、被車軸37可旋轉自如地支承之車輪35A，35B(以下也稱為車輪35)、及從連結部33突出而形成之2個臂部36A，36B(以下也稱為臂部36)，車軸37是從連結部33朝與操作桿部31的軸線S1大致正交的軸線T1方向延伸。 　　在連結部33的上端面33a設置圓柱狀的突出部34。突出部34形成為可***構成台車主體10的被連結部15之圓筒構件的貫通孔15a。 　　[0020] 因為車輪35A，35B設置成可旋轉自如，操作具30的操作桿部31如果沒有被支承就無法維持站立狀態。然而，如圖4等所示般，藉由讓臂部36與地面FL接觸而限制操作桿部31的傾動，操作桿部31能以若干傾斜的狀態維持站立狀態。 　　[0021] 接下來說明台車主體10和操作具30的連結動作。 　　為了將台車主體10和操作具30連結，首先，如圖4所示般，以操作具30之提升部32的連結部33位於貨台部10之被連結部15的下方的方式調整操作桿部31的姿勢(傾斜)及操作具30的位置。 　　具體而言，如圖5A所示般，讓操作具30接近設置於地面FL之貨台部11。這時，以連結部33之突出部34位於比被卡合部15之下端面15更下方的方式調整操作桿部31的傾斜。又如圖4所示般是設計成，在操作桿部31被車輪35及臂36支承的狀態下，使連結部33之突出部34配置於比被卡合部15的下端面15更下方。 　　[0022] 接下來，如圖5B所示般，讓操作具30靠近台車主體10，使連結部33之突出部34來到被卡合部15之貫通孔15a的正下方。接著，如圖5C所示般，讓操作桿部31朝傾動方向A1傾斜。傾動方向A1是與圖4及圖5A所示之操作桿部31的傾斜方向為相反方向。當讓操作桿部31朝傾動方向A1傾斜時，連結部33之突出部34的位置會往上方移動，使突出部34之一部分進入被卡合部15的貫通孔15a內，而使突出部34抵接於貫通孔15a的內周面，且使連結部33的上端面33a抵接於被卡合部15的下端面15b。亦即，使連結部33卡止於被卡合部15。 　　[0023] 當讓操作桿部31朝傾動方向A1傾斜時，如圖5D所示般，使藉由操作者的操作而作用於操作桿部31之傾動轉矩，以車輪37為支點而作為將連結部33的上端面33a所卡止之被連結部15的下端面15b往上方推的力發揮作用。在此同時，作為支點的車輪35會沿朝向貫通孔15a的下方位置之方向B1移動。利用該「槓桿作用」，使台車主體10之支承部12的下端面12b從地面FL上昇，而在地面FL和支承部12的下端面12b之間形成些微的間隙。 　　當讓操作桿部31朝傾動方向A1進一步傾斜時，如圖5E所示般，車輪35會更加靠近貫通孔15a的下方位置，而使車輪35所支承之貨台部11的荷重增大。作用於操作桿部31之與傾動方向A1為相反方向的轉矩也急劇減少，操作者幾乎感覺不到來自操作桿部31的反力。 　　如圖5F所示般，當車輪35到達貫通孔15a的下方位置時，被連結部15之下端面15b會全面地接觸連結部33的上端面33a，使車輪35和車輪13協作而支承貨台部11的荷重。藉此，與傾動方向A1為相反方向的轉矩變得不再作用於操作桿部31。這時，臂部36抵接於貨台部11的底面11b，而限制操作桿部31往傾動方向A1之進一步傾斜。結果，台車1成為圖1A所示的狀態。在此狀態下，連結部33成為相對於被連結部15可旋轉的狀態。此外，在支承部12的下端面12b和地面FL之間形成有些微的隙間，雖造成貨台部11也形成些微的傾斜，但該傾斜是對所裝載的荷物不致造成影響的範圍內之傾斜。 　　[0024] 在讓台車主體10和操作具30互相連結後的台車1，如圖6A所示般，可一邊將操作桿部31維持在沿台車主體10的長度方向L1，L2之方向，一邊將操作具推或拉，藉此讓台車前進或後退。 　　為了將台車1的移動方向改變，亦即為了將台車的移動方向往右方向或左方向改變，如圖6B所示般，是將操作桿部31相對於長度方向L1，L2彎向一方。因為連結部33相對於被連結部15是可旋轉的，能簡單地改變移動方向。 　　為了將台車主體10和操作具30分離，只要以與圖5A~圖5F相反的順序操作操作具30即可。 　　[0025] 依據本實施形態，特別是關於貨物散落，作為貨台部更佳為採用網籠。 　　[0026] 可對複數台的台車主體10各個準備操作具30，也能讓複數台的台車主體10共用一台的操作具30。 　　[0027] 在上述實施形態是例示出，被連結部15由圓筒構件形成且連結部33由圓柱狀構件形成的情況，但本發明並不限定於此，連結部33側是由圓筒構件所形成且被連結部15側是由突狀構件所形成亦可，被連結部、連結部的構造可做各種的改變。 　　在上述實施形態是例示出設有支承部12A，12B的情況，但本發明並不限定於此，場所、形狀、個數可適宜地改變。 　　在上述實施形態，是對貨台部的形態例示各種形態，但並不限定於此，可對應於圓棒鋼的搬運等之與工廠的資材搬運有關之所有裝載物而構成。[0014] Hereinafter, the embodiments of the present invention will be described with reference to the drawings.　　 Figures 1A to 3 show a trolley structure according to an embodiment of the present invention.

The directions of the wheels 13A, 13B are fixed.　　[0016] The support portions 12A, 12B are formed of steel or the like, are located at the ends of the lower surface 11b of the cargo bed portion 11 on the opposite side to the wheels 13A, 13B side, and are provided at both ends in the lateral directions M1, M2. The supporting parts 12A and 12B are for contacting the lower end surface 12b with the ground surface FL. In a state where the support portions 12A, 12B are in contact with the ground FL, the two support portions 12A, 12B and the two wheels 13A, 13B cooperate to hold the cargo bed 11 substantially horizontally, and support the load from the cargo bed 11. By making the lower end surfaces 12b of the support portions 12A and 12B contact the ground FL, the heavier the weight of the goods loaded on the cargo bed 11, the greater the friction between the lower end surface 12b and the ground FL, and the trolley body 10 The more difficult it is to move on the ground FL. [0017] The connected portion 15 is provided at approximately the middle position between the two supporting portions 12A, 12B, and is composed of a metal cylindrical member, has a through hole 15a, and has an annular lower end surface 15b. It engages with the connection part 33 of the operation tool 30 mentioned later. The connected portion 15 is fixed to the lower surface 11b of the cargo bed 11 by welding.　　[0018] As shown in FIG. 3, the operating tool 30 includes an operating rod portion 31 extending linearly, and a lifting portion 32 provided on the lower end side of the operating rod portion 31. "At the upper end of the operating lever portion 31, a handle portion 31a for the operator of the operating trolley 1 to hold is provided so as to extend horizontally in a direction orthogonal to the operating lever portion 31. [0019] The lifting portion 32 is provided at the lower end portion of the operating lever portion 31, and is provided with a connecting portion 33 formed at the lower end portion of the operating lever portion 31, and wheels 35A, 35B rotatably supported by the axle 37 ( Hereinafter, it is also referred to as a wheel 35), and two arm portions 36A, 36B (hereinafter also referred to as the arm portion 36) formed by protruding from the connecting portion 33, the axle 37 is from the connecting portion 33 toward the axis S1 with the operating lever portion 31 The substantially orthogonal axis T1 extends in the direction. "A cylindrical protrusion 34 is provided on the upper end surface 33a of the connecting portion 33. The protruding portion 34 is formed as a through hole 15 a into which a cylindrical member constituting the connected portion 15 of the trolley body 10 can be inserted.　　[0020] Because the wheels 35A and 35B are rotatably arranged, the operating lever portion 31 of the operating tool 30 cannot be maintained in a standing state if it is not supported. However, as shown in FIG. 4 and the like, by allowing the arm portion 36 to contact the ground FL to restrict the tilting of the operating rod portion 31, the operating rod portion 31 can maintain a standing state in a slightly inclined state.　　[0021] Next, the connection operation of the trolley body 10 and the operating tool 30 will be described. In order to connect the trolley body 10 and the operating tool 30, first, as shown in FIG. 4, the operating lever is adjusted so that the connecting portion 33 of the lifting portion 32 of the operating tool 30 is located below the connected portion 15 of the cargo bed portion 10. The posture (inclination) of 31 and the position of the operating tool 30.　　 Specifically, as shown in FIG. 5A, the operating tool 30 is brought close to the cargo platform 11 provided on the ground FL. At this time, the inclination of the operating lever portion 31 is adjusted so that the protruding portion 34 of the connecting portion 33 is located below the lower end surface 15 of the engaged portion 15. As shown in FIG. 4, it is designed so that the protrusion 34 of the connecting portion 33 is arranged below the lower end surface 15 of the engaged portion 15 when the operating lever portion 31 is supported by the wheel 35 and the arm 36.　　[0022] Next, as shown in FIG. 5B, the operating tool 30 is brought close to the trolley body 10, and the protruding portion 34 of the connecting portion 33 is brought to just below the through hole 15a of the engaged portion 15. Next, as shown in FIG. 5C, the operation lever portion 31 is tilted in the tilting direction A1. The tilting direction A1 is the opposite direction to the tilting direction of the operating lever portion 31 shown in FIGS. 4 and 5A. When the operating lever portion 31 is tilted in the tilting direction A1, the position of the protruding portion 34 of the connecting portion 33 moves upward, so that a part of the protruding portion 34 enters the through hole 15a of the engaged portion 15, and the protruding portion 34 The upper end surface 33a of the connecting portion 33 is brought into contact with the inner peripheral surface of the through hole 15a, and the lower end surface 15b of the engaged portion 15 is brought into contact. That is, the connecting portion 33 is locked to the engaged portion 15. [0023] When the operating lever portion 31 is tilted in the tilting direction A1, as shown in FIG. The force pushed upward by the lower end surface 15b of the connecting portion 15 locked by the upper end surface 33a of the connecting portion 33 acts. At the same time, the wheel 35 as a fulcrum moves in the direction B1 toward the lower position of the through hole 15a. With this "leverage", the lower end surface 12b of the support portion 12 of the trolley body 10 rises from the ground FL, and a slight gap is formed between the ground FL and the lower end surface 12b of the support portion 12. "When the operating lever portion 31 is further inclined in the tilting direction A1, as shown in FIG. 5E, the wheel 35 will be closer to the lower position of the through hole 15a, and the load of the cargo bed portion 11 supported by the wheel 35 will increase. The torque acting in the direction opposite to the tilting direction A1 that acts on the operating lever portion 31 also sharply decreases, and the operator hardly feels the reaction force from the operating lever portion 31. As shown in FIG. 5F, when the wheel 35 reaches the lower position of the through hole 15a, the lower end surface 15b of the connected portion 15 fully contacts the upper end surface 33a of the connecting portion 33, and the wheels 35 and 13 cooperate to support the cargo platform. The load of the part 11. Thereby, the torque in the opposite direction to the tilting direction A1 no longer acts on the operating lever portion 31. At this time, the arm portion 36 abuts on the bottom surface 11b of the cargo bed portion 11 to restrict the operation lever portion 31 from further tilting in the tilting direction A1. As a result, the trolley 1 becomes the state shown in FIG. 1A. In this state, the connecting portion 33 is in a rotatable state with respect to the connected portion 15. In addition, a slight gap is formed between the lower end surface 12b of the support portion 12 and the ground FL. Although the cargo bed portion 11 is also slightly inclined, the inclination is within a range that does not affect the loaded load. . [0024] After the trolley body 10 and the operating tool 30 are connected to each other in the trolley 1, as shown in FIG. The operating tool pushes or pulls to move the trolley forward or backward. "In order to change the moving direction of the trolley 1, that is, to change the moving direction of the trolley to the right or left, as shown in FIG. 6B, the operating lever portion 31 is bent to one side with respect to the longitudinal directions L1, L2. Since the connecting portion 33 is rotatable with respect to the connected portion 15, the moving direction can be easily changed.　　In order to separate the trolley main body 10 and the operating tool 30, it is only necessary to operate the operating tool 30 in the reverse order of FIGS. 5A to 5F.　　[0025] According to this embodiment, especially with regard to the scattered cargo, it is better to use a net cage as the cargo platform.　　[0026] The operating tool 30 can be prepared for each of the plurality of trolley main bodies 10, and a single operating tool 30 can also be shared by the plurality of trolley main bodies 10. [0027] In the above-mentioned embodiment, the case where the connected portion 15 is formed of a cylindrical member and the connecting portion 33 is formed of a cylindrical member is illustrated. However, the present invention is not limited to this, and the connecting portion 33 side is formed of a cylindrical member. The formed and connected portion 15 side may be formed by a protruding member, and the structure of the connected portion and the connected portion can be variously changed. "In the above-mentioned embodiment, the case where the support part 12A, 12B is provided is illustrated, but this invention is not limited to this, The location, shape, and number of objects can be changed suitably.　　 In the above-mentioned embodiment, various forms are exemplified for the form of the cargo bed part, but it is not limited to this, and it can be configured to correspond to all loads related to the material conveyance of the factory, such as the conveyance of round steel bars.
