摘要： An object is to provide a roller lifter which can maintain a proper dimensional accuracy of an outer diameter. A shaft (25) rotatably supporting a roller (30) is inserted through a pair of opposed portions (21) and swaged to be fixed. A cylindrical portion (61) is disposed to be fixed at a relative position to the opposed portions (21). Upon rotation of a cam (90), the cylindrical portion (61) is reciprocated via the roller (30). The roller lifter (10) includes a first member (20) in which the shaft (25) is swaged to be fixed to the opposed portions (21) and a second member (60) separate from the first member (20) and couplable via a coupling member to the first member (20). The second member (60) includes at least the cylindrical portion (61).

摘要： A lash adjuster includes a body, a plunger inserted into the body and having a bottom wall with a valve hole and a peripheral wall having an oil passage hole, and a partitioning member. The partitioning member is inserted into the plunger and has an oil passage end located above the oil passage hole in an inserted state. The partitioning member has a recess defining an oil passage together with the peripheral wall. The partitioning member defines a low-pressure chamber reserving hydraulic fluid and has, together with the recess, a press-fit portion abutting against an inner periphery of the peripheral wall when the partitioning member is inserted into the plunger. Consequently, the partitioning member has a deformed cross-sectional shape except for a circular shape when cut at a same height as the oil passage hole. The partitioning member has a same cross-sectional shape over its entire height.
摘要翻译：间隙调节器包括主体，插入到主体中的柱塞，具有带有阀孔的底壁和具有油通孔的周壁以及分隔构件。分隔构件插入柱塞中，并且在插入状态下具有位于油通道孔上方的油路端。分隔构件具有与周壁一起限定油通道的凹部。分隔构件限定了储存液压流体的低压室，并且当分隔构件插入到柱塞中时，与凹部一起形成有压靠在周壁的内周上的压配合部。因此，当在与油通孔相同的高度切割时，分隔构件具有除了圆形外形变形的横截面形状。分隔构件在其整个高度上具有相同的横截面形状。

摘要： A roller lifter for internal combustion engines is provided, which has higher rigidity of the lifter body, prevents cocking in the cylinder, and can achieve a size reduction. The roller lifter includes a cylindrical lifter body having a sliding surface on an outer circumferential surface thereof and a roller rotatably attached to the lifter body via an axial support pin and making contact with a rotating cam lobe. The lifter body includes a pair of support portions supporting the axial support pin. The axial support pin is mechanically fastened to the pair of support portions, with both ends thereof inserted in support holes formed in the support portions. The lifter body includes an anti-rotation retainer extending radially outward from the sliding surface. The sliding surface is formed on both front and rear sides in the sliding direction of the anti-rotation retainer.

摘要： 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.
摘要翻译：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。
