    摘要： The present invention provides a core piece and a reactor that have excellent bondability to a resin portion and are capable of reducing the generation of eddy currents. The core piece is a core piece that constitutes a magnetic core disposed within or outside a coil formed of a wound wire, the core piece including an end surface that is orthogonal to a magnetic flux flowing through the coil and to which a resin portion is bonded, wherein the end surface has an intersecting groove in which a plurality of grooves intersect without forming a loop. The core piece may be, for example, a powder compact made of metal particles and an insulating material present between the metal particles. The core piece may constitute, for example, a portion of the magnetic core, the portion being disposed within the coil.

    摘要： Provided is an in-vehicle power supply device that is less susceptible to the occurrence of sneak current between a main battery and a sub-battery that supply power externally. The in-vehicle power supply device includes a main battery for in-vehicle use, a sub-battery for in-vehicle use, a switch, a main power supply path, a sub-power supply path, a relay, and wiring. The switch has a first end connected to the main battery and the main power supply path, and a second end connected to the sub-battery. The relay has a first contact connected to a sub-power supply path, and a second contact connected to the second end. The first contact and the second contact form a pair. The wiring is a connection path that connects the first end and the first contact, and supplies power from the main battery to the sub-power supply path.

    摘要： A spot friction welding tool is for performing spot friction welding of a first member and a second member by superposing the first member and the second member and pressing the spot friction welding tool against the first member and the second member from the first member side. Each of the first member and the second member is a steel plate having a tensile strength of not lower than 590 MPa. The spot friction welding tool is rotatable around a rotation axis. The spot friction welding tool includes a column having a shoulder at a tip end thereof, and a cylindrical or truncated conical probe protruding from the shoulder in a direction of extension of the rotation axis.
