1. A vehicle fluid storage device comprising:
a storage container in which a storage space for fluid is formed and an opening is formed on one side or both sides; and
an assembly including a connector disposed adjacent to the opening and forming a path through which the fluid flows into and out of the storage space, and a holder disposed between the storage container and the connector to connect the storage container and the connector,
wherein the storage container and the holder are coupled to each other by rotation melting,
wherein the holder includes:
a storage container support region configured to surround the outer wall of the storage container and form a rotational melting region;
a connector support region extending from the storage container support region and disposed to surround at least one region of the connector; and
a connection region disposed between the storage container support region and the connector support region,
wherein the storage container includes an insert ring adjacent to a rotational melting region of the storage container and the holder,
wherein the insert ring is provided in the opening and configured to prevent deformation of the opening in the rotation melting of the storage container and the holder.
