A sufficient sealing property of a through hole is ensured. A sealing structure includes a cylindrically-shaped body part inserted into the through hole, formed of a thin plate of a first thickness, one end of the body part being open and another end of the body part being closed, a tapered part connected to the opened one end of the body part and including a diameter gradually expanding outward as a distance from the body part increases, and a first bent part connected to the tapered part, formed of a thin plate thinner than the first thickness, and bent inward so that a protruding part protruding outward elastically abuts against an inner peripheral surface of the through hole.

A stator structure for a rotary electric machine includes a stator core having a cylindrical shape in which slots and pole pieces are formed on an inner peripheral side and alternately arranged in a circumferential direction, a conductor segment which is a conducting wire having a rectangular cross section inserted in one of the slots through an insulator being connected with a conductor segment similarly inserted in another slot to form a coil. Each insulator has a shape including a pair of opposite side surface portions connected with an intermediate portion along a wall surface defining the slot. Each insulator includes end protrusions facing each other at free ends of the side surface portions to position the conductor segments. The insulators are made of an insulating and elastic material.

In a heat exchanger, fins are simply and accurately positioned in place and heat is efficiently exchanged without increasing manufacture cost, and the plurality of corrugated plate-like fins are disposed in the flow direction of a coolant in a housing. The heat exchanger has: connecting parts, which connect together the adjacent fins among the fins; protrusions formed on the connecting parts; and positioning holes for positioning the fins formed in the housing. The adjacent fins are disposed at predetermined intervals in the coolant flow direction with a predetermined offset amount in the direction that orthogonally intersects the coolant flow direction by fitting the protrusions in the positioning holes.

A semiconductor device and a method of producing the same, wherein a joining member and a joined member are bonded by means of brazing in a way such that no voids are left inside the joining layer. The semiconductor device comprises a joined member and a joining member which is joined to the joined member by means of brazing. The joined member is provided with a through hole which is open on the joining surface with the joining member, and a path communicating with the through hole is provided on at least one of the joining surface of the joining member with the joined member or the joining surface of the member with the joining member.
