Kind Code:
A1
Abstract:
This electric drive device has a first projection portion projecting from a holder surface. A plate-shaped portion is formed with a facing surface facing the holder surface. A first through-hole provided in the plate-shaped portion is formed by being surrounded by a first through-hole formation portion projecting from the plate-shaped portion toward the opposite side to the facing surface side. The inner surface of the first through-hole includes: a first intra-hole tilted surface tilted with respect to the facing surface in a direction toward which the inner diameter of the first through-hole becomes smaller from the facing surface toward an end of the first through-hole formation portion; and a first intra-hole cylindrical surface reaching the end of the first through-hole formation portion from the first intra-hole tilted surface while keeping the inner diameter of the first through-hole to be constant. The first projection portion is press-fit into the first through-hole in a state in which a plurality of first ribs are made contact with the first intra-hole cylindrical surface.
