Abstract: A vehicle drive unit includes an internal combustion engine (21), an electromotive unit (23) having a first electric motor (31) and a second electric motor (33), an inverter (27) disposed above the electromotive unit, a first harness (41) that electrically connects the inverter and a first terminal block (61) of the first electric motor, and a second harness (42) that electrically connects the inverter and a second terminal block (62) of the second electric motor. The first electric motor and the second electric motor are disposed in a vehicle front-rear direction. Of the first electric motor and the second electric motor, one electric motor is disposed on the front side in the front-rear direction, and the other electric motor is disposed on the rear side in the front-rear direction. The other electric motor is offset upward in the up-down direction with respect to the one electric motor.

Abstract: A rotational angle sensor includes a rotary plate and a printed circuit board in which a primary coil and a secondary coil group are arranged. Loops of the primary coil and the secondary coil group are along a surface of the printed circuit board. The rotary plate includes a target portion whose outer circumferential edge portion has a sine-wave shape. The primary coil overlaps with the target portion, and has a circular-arc shape along a rotational direction of the rotary plate. The secondary coil group includes 4n (n is a natural number) secondary coils arranged in a line along the rotational direction, on an inner circumferential side of the primary coil. The number of turns of a secondary coil on an end side in a line is smaller than that of a secondary coil on an inner side in the line.

Abstract: A board fixing structure includes: a resin-made holder; a metal-made terminal held by the holder; and a circuit board connected to the terminal, in which the terminal has a proximal end portion, a fixing portion extending from the proximal end portion and fixedly soldered to the circuit board, and a support portion extending from the proximal end portion and coming into contact with a rear surface of the circuit board so as to support the circuit board, and the fixing portion and the support portion are separated from each other in a plane direction of the circuit board.

Abstract: A displacement detection apparatus for a linear motion mechanism includes a nut member, a rod including elongate grooves elongating in an axial direction of the rod and a through hole, a permanent magnet disposed parallel to the rod, a magnet block made of synthetic resin and including a retaining portion holding the permanent magnet, a pair of leg portions extending from ends of the retaining portion that are spaced apart, and a nut made of metal insert-molded at an intermediate position between the pair of leg portions, and a displacement sensor disposed opposing to the permanent magnet. The pair of leg portions and the nut of the magnet block are disposed in the elongate groove of the rod and the magnet block is fixed to the rod by a bolt screwed to the nut, the bolt penetrating through the through hole extending through the rod.
