Abstract: A shock absorber includes a cylinder which is a conductor; a rod inserted into the cylinder from one end side of the cylinder, a suspension spring arranged outside the cylinder, a spring receiver which receives a load of the suspension spring on the one end side of the rod, and a protective member arranged on the one end side of the rod and configured to protect the rod. The protective member has a coil configured to detect a relative position between the cylinder and the protective member, and an end portion formed on the one end side of the protective member is arranged so as not to receive a load from the spring receiver.

Abstract: A vehicle height adjustment device includes front forks, a rear suspension, a weight estimation unit, and a front wheel-side target movement amount determination unit. The front fork includes a front wheel-side suspension spring and a front wheel-side support member, which supports one end of the front wheel-side suspension spring, and moves toward another end of the front wheel-side spring to change the front wheel-side suspension spring length. The rear suspension includes a rear wheel-side suspension spring and a rear wheel-side support member, which supports one end of the rear wheel-side suspension spring, and moves toward another one end of the rear wheel-side spring to change the rear wheel-side suspension spring length. The weight estimation unit estimates a weight applied to a vehicle. The front wheel-side target movement amount determination unit decreases, a movement amount of the front wheel-side support member as the estimated weight increases.

Abstract: An embodiment provides a vane pump device. In the vane pump device, vane grooves of a rotor include columnar grooves which accommodate oil, and support the vanes. An inner-plate low pressure side recess portion and an inner-plate high pressure supply region are provided along a rotation direction of the rotor. The inner-plate low pressure side recess portion supplies oil to the columnar grooves at a first pressure, and the inner-plate high pressure supply region supplies oil at a second pressure higher than the first pressure. A size from an inner-plate low pressure side recess portion downstream end to an inner-plate high pressure side through-hole upstream end in the rotation direction is different from that from an inner-plate high pressure side recess portion downstream end to an inner-plate low pressure side recess portion upstream end in the rotation direction.

Abstract: A vehicle height adjustment device includes a spring having one end supported on a vehicle body side and another end supported on a wheel side. An adjustor includes an accommodation chamber accommodating fluid and adjusts a length of the spring in accordance with an amount of fluid in the accommodation chamber. A storage chamber stores fluid. A guide passage guides fluid from the accommodation chamber to the storage chamber. An actuator includes an operation rod to press a push rod. A valve body closes the guide passage when seated on a seat and opens the guide passage when pressed and detached from the seat by the push rod. A press member includes a contact portion and a shaft. The press member presses and seats the valve body on the seat. An accommodation member accommodates the valve body and the contact portion. A support member supports the shaft movably.

Abstract: There is provided a compact damping force variable shock absorber capable of implementing different adjustments for a compression-side stroke and an extension-side stroke as initial settings. A damping force variable device in one embodiment includes: a main valve that opens and closes to control flow of oil caused by sliding of a piston in a cylinder, thereby generating damping force; a pilot chamber into which a portion of the flow of the oil is introduced so that internal pressure is applied to the main valve in a valve-closing direction; a pilot valve that opens and closes to adjust the internal pressure of the pilot chamber; and a communication passage that communicates the pilot chamber with a rod-side oil chamber or a piston-side fluid chamber.

Abstract: A vehicle height adjustment apparatus includes a control device. The control device controls the opening degree of the solenoid valve to allow a movement amount of the support member to reach a movement amount target value that corresponds to the vehicle height set in advance, in accordance with the weight applied to the vehicle. The control device controls the opening degree of the solenoid valve to change the movement amount of the support member based on a difference between a value based on the information related to the vehicle height and a vehicle height-related target value, on condition that the movement amount of the support member reaches the movement amount target value and the value based on the information related to the vehicle height obtained by the information obtaining device does not reach the vehicle height-related target value that corresponds to the vehicle height set in advance.
