Abstract: A shunt resistor the resistive value of which can be lowered simply and easily has: a first resistive body, two base materials that sandwich the first resistive body therebetween and are joined by a welding to the first resistive body, and a second resistive body joined by a welding to the two base materials at different positions from the first resistive body. In addition, the second resistive body can come into contact with the first resistive body.

Abstract: A coil spring of this invention includes a first end coil part with a first bearing surface facing to the first side in the axial direction, a second end coil part with a second bearing surface facing to the second side in the axial direction and a central coil part connecting the first and second end coil parts. A displacement length in the axial direction from the outer end portion until the inner end portion of the first end coil part is a thickness of a spring wire forming the coil spring so that a space between the outer end portion of the first end coil part and an inner end portion of the central coil part is zero, and a displacement length in the axial direction between the outer end portion of the first end coil part and a point away along the circumferential direction from the outer end portion toward the inner end portion of the first end coil part by a half of turn around the axial line is less than a half of the thickness of the spring wire.

Abstract: A shunt resistor having sufficient bonding strength includes a resistor, a pair of bases which are integrally formed with the resistor so as to sandwich the resistor, recessed holes which are respectively formed in the bases, and measurement terminals which are inserted into the recessed holes and are affixed to the bases. Each measurement terminal has a shaft part and a flange part that protrudes outwardly in the circumferential direction of the shaft part. Each recessed hole is formed to have a diameter smaller than the diameter of the flange part, and the shaft parts are respectively inserted into the recessed holes.

Abstract: A bearing body is provided. The bearing body includes first and second support surfaces inclined so as to slope upward from a side on the imaginary central vertical plane passing through an axis of a rotating shaft to be supported toward one and the other outer sides in the width direction of the rotating shaft. First and second transitional regions that respectively make transitions from the first and second support surfaces to a first and end surface of the bearing body on one side in the axial direction of the rotating shaft have a curved shape projecting obliquely upward such that an orientation of a normal line changes from a perpendicular direction to a parallel direction with respect to the axis of the rotating shaft toward one side from the other side in the axial direction of the rotating shaft.

Abstract: A region extending over a predetermined distance from a first latch claw center portion, out of an end part on one side in the longitudinal direction of a first latch claw opening, toward one side in the longitudinal direction is bulged radially inward to form a first latch claw while both sides of the center portion do not form the first latch claw. A region extending over a predetermined distance from a second latch claw center portion, out of an end part on the other side in the longitudinal direction of a second latch claw opening, toward the other side in the longitudinal direction is bulged radially outward to form a second latch claw while both sides of the center portion do not form the second latch claw.

Abstract: A method for producing a multi-layer bus bar unit includes preparing a plurality of metal flat plate-shaped bus bars, each with electrode terminal parts at two or more locations, depositing a coating film over an entire surface of each bus bar by electrodeposition coating, subjecting a coating film of a predetermined bus bar to a heating treatment so that the coating film is completely cured, subjecting another bus bar to a heat treatment so that the bus bar is semi-cured, and obtaining a multi-layer structure by alternately overlapping, and then subjecting to a pressure and heating treatment, the bus bar with the completely-cured coating film and the bus bar with the semi-cured coating film, so that the semi-cured coating film is completely cured and the plurality of bus bars adhere to each other by the completely-cured coating film.
