         2 . The vehicle fluid storage device of  claim 1 , wherein the storage container and the holder include a plastic material,
 the first and second connectors include at least one material of metal and aluminum, and   the first connection area and the holder are connected by insert injection.   
     
     
         3 . The vehicle fluid storage device of  claim 2 , wherein a burr receiving portion configured to receive burrs generated by the welding is formed between the storage container and the holder. 
     
     
         4 . The vehicle fluid storage device of  claim 3 , wherein the burr receiving portion is formed recessed in an outer diameter portion of the holder facing an inner wall of the storage container. 
     
     
         5 . The vehicle fluid storage device of  claim 3 , wherein the burr receiving portion is formed recessed in the second connector between the storage container and the holder. 
     
     
         6 . The vehicle fluid storage device of  claim 1 , wherein the second connector is connected to the second connection area and is in close contact with the first connection area and an end portion of the storage container. 
     
     
         7 . The vehicle fluid storage device of  claim 1 , further comprising a leakage prevention portion for maintaining a seal between the first and second connectors. 
     
     
         8 . The vehicle fluid storage device of  claim 7 , wherein the leakage prevention portion includes at least one of an O-ring and an injection backup ring. 
     
     
         9 . The vehicle fluid storage device of  claim 7 , wherein the leakage prevention portion includes
 a first ring member disposed between the holder surrounding the first connection area and the second connector,   a second ring member disposed adjacent to an end of the holder between the first connection area and the second connection area, and   a third ring member disposed between the second connector and the second connection area.   
     
     
         10 . The vehicle fluid storage device of  claim 1 , wherein the holder further includes at least one insert member each inserted into at least one connection groove formed to be recessed in the first connection area, and
 a cross section at least one of the insert members is tapered from an inside of the connection groove toward an outside of the connection groove.   
     
     
         11 . The vehicle fluid storage device of  claim 2 , further comprising includes a reinforcing layer disposed to surround at least one area of the storage container and the first and second connectors to reinforce strength,
 wherein the reinforcing layer includes at least one of a carbon fiber composite material and a glass fiber composite material.   
     
     
         12 . The vehicle fluid storage device of  claim 1 , wherein the storage container is formed by blow molding. 
     
     
         13 . The vehicle fluid storage device of  claim 1 , wherein the welding includes at least one of spin welding and laser welding. 
     
     
         14 . A method for manufacturing a vehicle fluid storage device including a storage container having a fluid storage space formed inside and an opening portion formed at least one of one side and the other side, a first connector including a first connection area disposed adjacent to the opening portion on the inside of the storage container and a second connection area extending from the first connection area, a second connector connected to the first connector so that the first connector and an external device are connected, and a holder connected to the first connection area between the storage container and the first connection area and coupled to the storage container by spin welding, the method comprising:
 forming an assembly of the first connector and the holder; and 
 causing the first connector to be adjacent to the opening portion and coupling the holder and the storage container by welding. 
 
     
     
         15 . A vehicle fluid storage device assembly comprising:
 a plurality of vehicle fluid storage devices; and   a connection portion connecting the fluid storage device to an external device,   wherein each of the fluid storage devices includes   a storage container having a fluid storage space formed inside and an opening portion formed at least one of one side and the other side,   a first connector including a first connection area disposed adjacent to the opening portion on the inside of the storage container and a second connection area extending from the first connection area,   a second connector connected to the first connector so that the first connector and an external device are connected, and   a holder connected to the first connection area between the storage container and the first connection area and coupled to the storage container by welding.
