Manufacturing method for fuel pump
Abstract:
A stator has ribs, which are configured to make contact with an inner wall of a housing when accommodated in the housing. In a deformation process, force is applied from a radially outside to first portions of the housing to elastically deform the housing. In an insertion process subsequent to the deformation process, the stator is inserted into the housing, such that the ribs are enabled to make contact with second portions of the housing, which are elastically deformed radially outward. In an affixation process subsequent to the insertion process, application of the force is released to cause the ribs to make contact with an inner wall of the housing.
