To achieve both a reduction in weight of a toilet room and an improvement in strength thereof. A vehicle with a toilet includes a toilet room including a side-surface part and a ceiling part connected to the side-surface part. The side-surface part includes a plate-like side-surface outer plate extending in a vertical direction, and an upper-end edge frame extending in a longitudinal direction and connected to an inner-side upper-end edge of the side-surface outer plate. The ceiling part includes a plate-like ceiling outer plate extending in a horizontal direction, and a side-end edge frame extending in the longitudinal direction and connected to an inner-side side-end edge of the ceiling outer plate. The upper-end edge frame of the side-surface part and the side-end edge frame of the ceiling part are connected to each other by at least one rod-like reinforcing member.

Vehicle with toilet

A stator includes a stator coil formed of electric wires which include a joined pair of first and second electric wires. The first electric wire has a lead portion led out from the radially inner periphery of a first slot of a stator core and including a crossover part. The crossover part crosses over an axial end face of an end part of the stator coil from the radially inside to the radially outside of the axial end face; the end part protrudes from an axial end face of the stator core. The second electric wire has a lead portion led out from the radially outer periphery of a second slot of the stator core. The lead portions of the electric wires are joined together with a joint formed therebetween. The joint is positioned closer to the axial end face of the stator core than the crossover part is.

Stator for electric rotating machine

A stator includes a stator coil that is formed of a plurality of electric wires each being comprised of an electric conductor having a substantially rectangular cross section and an insulating coat covering the electric conductor. The electric wires include a pair of first and second electric wires each having an end portion where the electric conductor is not covered by the insulating coat. Each of the end portions of the two electric wires includes a joined part at a distal end thereof; the joined parts of the end portions are joined together. At least one of the first and second electric wires has a bent part that is bent only once and adjoins the joined part of the end portion of the electric wire. The end portion of the at least one of the first and second electric wires includes at least part of the bent part.

An electric rotating machine as disclosed herein includes an armature core having an outer peripheral portion with slots, a rotatable shaft having an outer periphery and rotatably supporting the armature core, a plurality of lower layer coils each having at opposite ends thereof respective lower layer coil protrusion portions, and a plurality of upper layer coils disposed radially outside of the lower layer coils and each having at opposite ends thereof respective upper layer coil protrusion portions. According to the novel method of this invention, the lower layer coil protrusion portions are bonded to the upper layer coil protrusion portions with a welding torch of an arc welding machine by radially moving at least one of the welding torch and boundary portions, at which the corresponding protrusion portions abut one another, relative to each other. By radially moving the welding torch and the boundary portions relative to each other, circumferentially adjacent bonded protrusion portions are smaller, mechanically stronger, and do not abut against one another.

Method for bonding rotors of an electric rotating machine

An armature for an electric rotating machine has a plurality of outer coil elements and a plurality of inner coil elements. Each of the coil elements has end protrusions extending axially outwardly from an axial side of an armature. The end protrusions facing each other in a radial direction is joined by an arc welding. In one method, the end protrusion of the outer coil element is formed a projection at an axially inside of an axial end of the protrusion. The end protrusions are held spaced apart from each other in the radial direction while contacting only through the projection. The axial ends of the protrusions are welded by swinging the welding arc. In another method, a ring-shaped brazing material is interposed between the end protrusions. The brazing material is melted by the welding arc to weld the end protrusions, while cutting out the brazing material existing between two adjacent pairs of the end protrusions.
