摘要:
A connecting structure to connect electronic components electrically through a plurality of conducting lines each including a covered segment including a wire conductor covered with an insulating covering and an uncovered segment includes a molding unit and a sealing unit. The molding unit encloses a boundary portion between the covered segment and the uncovered segment of each of the conducting lines so that the uncovered segments project in a first direction from a first end of the molding unit and the covered segments project in a second direction from a second end of the molding unit, and thereby holding the conducting lines to fix positions of the conducting lines relative to one another. The sealing member of an adhesive adheres to the second end of the molding unit and adheres to each of the covered segments of the conducting lines projecting from the second end of the molding unit.

A motor drive apparatus includes a motor unit including an output shaft and a first terminal connecting portion; a control board including a second terminal connecting portion, and configured to control a current supply to the motor unit; a housing; a shaft supporting portion supporting the output shaft; and a plurality of relay terminals electrically connecting the first terminal connecting portion with the second terminal connecting portion. The housing includes a motor-unit receiving portion receiving the motor unit, and a board receiving portion formed integrally with the motor-unit receiving portion. The motor-unit receiving portion is formed with an opening on one side of the motor-unit receiving portion in an axial direction of the motor unit and includes a wall portion on another side of the motor-unit receiving portion in the axial direction. The wall portion is formed with a through-hole. The board receiving portion is formed with an opening in the axial direction to receive the control board. The plurality of relay terminals are provided via the through-hole of the wall portion.

First and second shafts are connected with each other through a torsion bar and arranged to rotate relative to each other within a relative rotational angle range A. A s torque sensor includes first and second resolvers for sensing the angular potions of the first and second shafts, respectively. The first resolver produces a periodical first resolver output signal so that the number X1 of cycles per revolution of the first shaft is smaller than 360/A (X1
摘要:
A worm wheel including an annular worm wheel main body formed from a resin material by injection molding, a plurality of teeth disposed on an outer periphery of the worm wheel main body in a circumferential direction of the worm wheel main body, wherein a non-cutting region is provided on respective tooth flanks of the teeth and located offset from a mid-position of a whole depth of the respective teeth in a radially outward direction of the worm wheel main body, the non-cutting region being not formed by cutting by a hob after completion of the injection molding, and a cutting region is provided on the respective tooth flanks, the cutting region being formed by cutting by the hob after completion of the injection molding.
