Abstract: The hydraulic damper 1 includes: a cylinder 11 storing oil; a piston unit connected to a rod moving in an axial direction and configured to move within the cylinder 11; an outer cylinder body 12 outside of the cylinder 11 and forming a communication path L through which oil flows along with movement of the piston unit; a damper case 13 outside of the cylinder 11 and forming a reservoir chamber R to retain oil; a damping force changer 52 external to the cylinder 11 and configured to generate a damping force by throttling flow of oil along with movement of the piston unit and configured to change magnitude of the damping force; and a joint piece 61 forming a channel 61R of oil from the communication path L to the damping force changer 52 and including an external valve to control flow of oil flowing through the channel 61R.

Abstract: A hydraulic buffer device includes a first cylinder that stores oil, a rod member capable of being moved with respect to the first cylinder as being inserted into the first cylinder toward a first side of the first cylinder and being protruded outward from the first cylinder on a second side of the first cylinder, a rod guide that covers the second side of the first cylinder as having a through-hole, an oil seal arranged at the outer side of the rod member in the radial direction on the second side of the first cylinder, a groove portion that forms a flow path for oil flowing from the inside of the first cylinder toward the oil seal, and a small-diameter portion that restricts flow of oil flowing through the groove portion. An appropriate amount of fluid is supplied to a seal member in a pressure buffer device.

Abstract: An elastic sheet includes: a seating portion by which the coil spring is supported and which has a circular arc shape in a view from the axial direction, one circumferential side of the seating portion being a side of entry of the coil spring; and a pair of sidewall portions extending from respective width-wise opposite ends of the seating portion toward the coil spring side, at least one of the sidewall portions has a wire contact surface that contacts a wire forming the coil spring and an inclined surface inclined so as to approach the spring bearing as the inclined surface extends widthwise outward from the wire contact surface, and a radius of curvature of the wire contact surface at least at a side closest to the inclined surface is smaller than a radius of the wire.
