Claims

[Scope of utility model registration request]

An armature is disposed at the center of the interior of a cylindrical housing that forms a liquid passage, and a pair of magnets are directly fixed to the inner surface of the housing at a predetermined distance from the armature. , an electric pump having a structure that has both the role of a casing and the role of a yoke constituting a magnetic circuit by the magnet, wherein a magnet holder is installed between each of the magnets in the circumferential direction of the housing, The magnet is held between the magnet holders, and at least one of the magnet holders is locked to a locking portion formed on the inner surface of the housing, so that the magnet holder is moved in the circumferential direction of the housing. and a transfusion pump, characterized in that the position of the magnet is fixed by restricting movement in the axial direction of the housing 2'.
