Abstract: The hydraulic shock absorber includes a cylinder containing a fluid, a damper case positioned outside the cylinder to form a reserving chamber, a piston housed inside the cylinder, a piston rod supporting the piston, a rod guide covering one end of the cylinder, and a guide bushing provided with a through hole through which the piston rod penetrates. The rod guide has an outer circumferential groove formed by spacing apart at least a part of the rod guide from the cylinder in a circumferential direction of the cylinder for allowing the fluid to flow from inside of the cylinder to the reserving chamber, and has an inner circumferential groove for supplying the fluid into an inner circumferential gap between an inner circumferential surface of the guide bushing and an outer circumferential surface of the piston rod as the fluid flows through the outer circumferential groove.

Abstract: The hydraulic damping device includes: a cylinder storing fluid; a piston configured to form a channel through which the fluid flows along with relative movement of a rod relative to the cylinder in a specific direction; a valve having elasticity, the valve being configured to open and close the channel in the piston; a movement permitting part configured to permit the valve to move between a contact position and a spaced position, the contact position being a position where the valve contacts the piston, the spaced position being a position where the valve is spaced from the piston; a restricting part configured to restrict bending of the valve at the spaced position; and an imparting part having elasticity, the imparting part being configured to impart, to the valve, a load that is uneven in a circumferential direction of the valve and directed toward the piston.

Abstract: Provided is an examination method for a damping force variable mechanism, the examination method including: an operation step of operating a damper in a state in which the damper is installed in a vehicle, the damper being provided with a damping force variable mechanism that changes a damping force according to an input current (an example of a signal); and a detection step of detecting an induction current (an example of an output from the vehicle) from the damping force variable mechanism of the damper installed in the vehicle, wherein a detection device that performs the operation of the detection step is provided. Thus, the damping force variable mechanism of a pressure damping device can be examined in a state in which the damping force variable mechanism is installed in the vehicle.
