Abstract: A rotating electric machine includes a stator core, a stator winding, and a rotor rotatably disposed via an air gap so as to be allowed to rotate relative to the stator core. A magnetic resistance-altering portion is provided on every other magnetic pole of magnetically-assisted salient pole members. A magnetic pole provided with the magnetic resistance-altering portion and a magnetic pole without the magnetic resistance-altering portion are alternately arranged.

Abstract: Provided is an exhaust apparatus for a vehicle, being capable of performing a normal detection of a nitrogen oxide (NOx) concentration in exhaust gas without involving increase in the size and the cost. The exhaust apparatus includes an exhaust pipe having an upstream end connected to an aftertreatment device and a downstream end enclosing an exhaust port at a position higher than the upstream end, a NOx sensor to be retained in the exhaust pipe, and a water barrier wall provided inside the exhaust pipe. The water barrier wall has a shape to form a shield between the NOx sensor and the exhaust port while leaving a gas inlet that allows the exhaust gas to flow to the NOx sensor from the aftertreatment device through the gas inlet.

Abstract: Provided is a gasket effectively suppressing heat transfer from an exhaust pipe with an injector retention section to a reducing-agent injector. The gasket includes a first plate to contact a retaining wall of the injector retention section, the first plate having a first opening allowing the reducing agent to be injected and a first bolt insert-through hole, a second plate disposed closer to the reducing-agent injector than the first plate, the second plate having a second opening allowing the reducing agent to be injected and a second bolt insert-through hole, and a spacing keeping member that retains a spacing between the first and second plates to form a heat insulation space therebetween. The heat insulation space has a shape allowing at least a part of the heat insulation space to communicate with the outside of the gasket between the first and second plates.
