Abstract: A vehicle height adjustment device includes a changer and a controller. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The controller is configured to control the changer to make the relative position a target value so as to control a vehicle height of the body of the vehicle. The controller is configured to control the changer to maintain the relative position irrespective of the target value when a decreasing malfunction occurs causing the vehicle height to decrease.

Abstract: A stroke sensor system includes a vehicle-body-side member, a wheel-side member, and a movement-amount deriving section. The movement-amount deriving section derives a movement amount of relative movement between the vehicle-body-side member and the wheel-side member. At least a part of one of the vehicle-body-side member and the wheel-side member is a conductor, and the other is provided with a coil. The movement-amount deriving section includes an even number of capacitors and an even number of exciting sections. The even number of capacitors are electrically coupled to the coil and configure an LC resonance section. The even number of exciting sections are for exciting an oscillation waveform output by the LC resonance section. The even number of capacitors and the even number of exciting sections are divided into equal numbers to configure a balanced circuit. The movement-amount deriving section derives the movement amount based on the oscillation waveform.

Abstract: One embodiment provides a damping force generator. The damping force generator includes: a valve body having a compression-side inlet port into which the oil pushed by the piston flows; and a compression-side damping valve provided so as to block a port outlet and elastically deformed according to pressure of the oil flowing into the compression-side inlet port to thereby exhibit damping force. An opening cross-sectional area of a port inlet opening is larger than a passage cross-sectional area of the compression-side inlet port.
