Abstract
A pump apparatus includes: a first housing member which includes a first drive shaft insertion hole; a second housing member which includes a second drive shaft insertion hole; a pump drive shaft; a first abutment portion and a second abutment portion formed in the second housing member; the first and second drive shaft insertion holes being previously co-processed in a state in which the first and second housing member are relatively positioned by abutments between the first and second positioning protruding portions and the first and second abutment portions, and a joining member joining the first and second housing members in a state in which the first and second housing members are relatively positioned by the abutments of the first and second positioning protruding portions and the first and second abutment portions so as to re-create a relative position between the first and second housing members at the co-processing.
