Abstract: A lash adjuster includes a bottomed cylindrical body and a cylindrical plunger reciprocably inserted into the body and having a bottom wall and a peripheral wall. The plunger has a low-pressure chamber. The peripheral wall of the plunger includes an annular band portion abutting against an upper part of a peripheral wall of the body. The peripheral wall of the plunger has a plurality of plunger oil holes located below the band portion. The plunger oil holes include respective lower ends defining a level of the oil stored in the low-pressure chamber. The plurality of plunger oil holes are located at a common height position of the peripheral wall of the plunger coming close to the band portion.

Abstract: A method of manufacturing a supporting structure includes disposing a supported member between a pair of opposed support walls, the support walls and the supported member having shaft holes formed coaxially through the support walls and the supported member respectively, inserting a shaft member through the shaft holes in the disposed state, the shaft member having two ends each having a peripheral portion circumferentially divided into a plurality of swaging portions continuous without discontinuity and swaging the swaging portions sequentially such that regions of the shaft member corresponding to the respective swaging portions are fixed in the shaft holes. The swaging portions include first swaging portions and second swaging portions, both of which are disposed so as to be paired at both radial sides of the shaft holes, respectively. A larger swage load is applied to each first swaging portion than to each second swaging portion.

Abstract translation: 一种制造支撑结构的方法包括：将支撑构件设置在一对相对的支撑壁之间，所述支撑壁和所述被支撑构件具有分别通过所述支撑壁和所述支撑构件同轴地形成的轴孔，将轴构件穿过所述轴孔 在所述设置状态下，所述轴构件具有两个端部，每个端部具有圆周分割成多个不间断地连续的型锻部分，并且顺序地使所述型锻部分顺序地锻造，使得与相应的锻造部分对应的轴构件的区域固定在 轴孔。 型锻部分包括分别设置成在轴孔的两个径向侧配对的第一锻件部分和第二锻模部分。 每个第一模锻部分施加较大的模压载荷，而不是每个第二挤压部分。

Abstract: A bearing device includes a support having a bearing hole, a shaft member slidably inserted into the bearing hole thereby to be rotatably supported by the support, the shaft member having an axial end surface and a locking part located on the axial end surface of the shaft member to protrude in an axial direction of the shaft member from an outer periphery of the axial end surface of the shaft member. The locking part is deformed by force applied to its axial protruding end so as to bulge outward in a radial direction intersecting the axial direction, so that the bulging part is capable of being locked to a peripheral part of the bearing hole on an outer surface of the support.
