Abstract: A roller lifter includes a lifter body having a cylindrical peripheral wall and a roller rotatably mounted on the lifter body via a shaft member and brought into contact with a cam. The peripheral wall has an outer periphery formed with a sliding surface which is slid on an inner wall of a cylinder. The lifter body has a rotation stopper formed by outwardly protruding a part of the peripheral wall, and an opening formed in another part of the peripheral wall which another part is radially opposed to the rotation stopper. The opening is open so that the rotation stopper oppositely faces the opening.

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: 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.

Abstract: 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).

Abstract: A lash adjuster includes a plunger having a bottom wall with a valve hole and a peripheral wall having an oil passage hole and an inner periphery formed with a recessed groove, the plunger defining a high-pressure chamber between the bottom wall and a body, and a partitioning member having an oil passage end located above the oil passage hole. The partitioning member has an oil-passage defining portion located opposite the recessed groove and defining an oil passage between itself and a groove face of the recessed groove. The partitioning member defines a low-pressure chamber reserving a hydraulic fluid flowing through the oil passage hole, the oil passage and the oil passage end. The low-pressure chamber causes the reserved hydraulic fluid to flow through the valve hole into the high-pressure chamber. The partitioning member is formed into a cylindrical shape and extends in an up-down direction without any stepped part.
