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.
Abstract translation: 弹性片包括：螺旋弹簧被支撑并且从轴向看呈圆弧形状的安置部，所述座部的一个周向侧是所述螺旋弹簧的入口侧; 以及一对侧壁部分，其从所述就座部分的相应的宽度方向的相对端向所述螺旋弹簧侧延伸，所述侧壁部分中的至少一个具有与形成所述螺旋弹簧的线接触的线接触表面和倾斜的倾斜面 当倾斜表面从电线接触表面向宽度方向向外延伸时接近弹簧轴承，并且电线接触表面的至少在最接近倾斜表面的一侧的曲率半径小于电线的半径。

Abstract: A pressure shock absorbing apparatus includes: a first cylinder; a second cylinder that is placed outside the first cylinder to form a liquid storage unit; a partitioning member that is disposed in such a manner as to be movable in an axial direction inside the first cylinder to partition a space inside the first cylinder; a throttle mechanism that is disposed in a side portion of the second cylinder, and includes a throttle unit that throttles a flow path cross section of a liquid to discharge the liquid taken in from the first cylinder toward the liquid storage unit while passing the liquid through the throttle unit; and a suppression unit that is held by the throttle mechanism at a liquid discharge point between the throttle mechanism and the liquid storage unit to suppress air bubbles in the liquid in the liquid storage unit.
Abstract translation: 一种压力冲击吸收装置，包括：第一气缸; 第二圆柱体，其被放置在第一圆筒的外部以形成液体储存单元; 分隔构件，其设置成能够在第一气缸内沿轴向移动，以分隔第一气缸内的空间; 节气门机构，其设置在所述第二气缸的侧部，并且包括节流单元，其节流液体的流路横截面，以将从所述第一气缸吸入的液体朝向所述液体存储单元排出，同时使所述液体通过 节气门单元; 以及抑制单元，其在节流机构和液体存储单元之间的液体排出点处被节流机构保持，以抑制液体存储单元中的液体中的气泡。

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.
