Abstract: In a rotation angle detecting device, a signal from a first magnetism detecting element is outputted to a signal output part of a first IC package. A first signal output terminal outputs the signal from the first magnetism detecting element to outside. A signal from a second magnetism detecting element is outputted to a signal output part of a second IC package. A second signal output terminal outputs the signal from the second magnetism detecting element to outside. At least one of a power supply terminal and a ground terminal is located between the first and second signal output terminals. A rotary drive unit includes the device, a motor that rotates a detection object, and a motor power source wire. The ground terminal and a motor power source terminal are adjacent to each other.

Abstract: A valve device includes a flow path formation member provided with at least one flow path hole through which a fluid passes, and a drive part that outputs a rotational force. The valve device includes a shaft, and a rotor having a sliding surface that slides while facing an opening surface of the flow path formation member where the flow path hole is opened, and the rotor is configured to increase or decrease an opening degree of the flow path hole with rotation of the shaft. The valve device includes an energization member that energizes the rotor toward the flow path formation member. The valve device includes a coupling structure configured to tiltably couple the shaft to the rotor such that a contact state between the sliding surface and the opening surface is held regardless of a posture or a position of the shaft.

Abstract: A valve device includes: a driving source making rotational motion; a rotated part provided rotatably around a predetermined axis; and a fluid passage portion having a flow hole for passing a fluid. The valve device further includes: a gear mechanism having gears to transmit rotational motion of the driving source to the rotated part by engagement between the gears to rotate the rotated part; and a biasing part biasing the rotated part toward one side in a circumferential direction with the predetermined axis at the center. The rotated part includes a rotor increasing or reducing an opening of the flow hole in conjunction with rotation of the rotated part and is rotated according to rotational motion of the driving source while being biased toward the one side in the circumferential direction by the biasing part.
