Abstract: A rocker arm includes a pair of sidewalls disposed along a heightwise direction so as to be opposed to each other. The sidewalls define a space to house a roller and have opposed portions extending in the heightwise direction relative to adjacent portions which are adjacent to the opposed portions. The opposed portions have thinner portions having smaller thicknesses than the adjacent portions.

Abstract: A lifter structure includes a cylindrical member configured to be reciprocally slid in a guide hole of a lifter guide according to rotation of a cam and having an engagement groove and a rotation-preventing member which is separate from the cylindrical member and is disposed so as to face an interior of the guide hole. The rotation-preventing member is inserted into the engagement groove to abut against a groove edge of the engagement groove in a rotation direction of the cylindrical member, thereby preventing the cylindrical member from rotation in the guide hole.

Abstract: A lifter includes a roller caused to abut against a cam thereby to be pressed and a lifter body rotatably supporting the roller and housed in a guide hole of a lifter guide so as to be reciprocable in the guide hole. The lifter body includes a cylindrical part and a rotation stopper. The cylindrical part has an outer periphery formed into a cylindrical shape such that the outer periphery is slidable on an inner periphery of the guide hole. The cylindrical part has one of two axial ends, the one end being formed with a skirt covering the roller. The rotation stopper is formed to protrude outward from the other axial end of the cylindrical part, the other axial end being located opposite a side where the skirt is located. The rotation stopper prevents the lifter body from being rotated about an axis thereof relative to the lifter guide.

Abstract: A lifter rotation preventing structure includes a lifter body, a retainer and a biasing member. The lifter body is inserted into a sliding hole of a housing and reciprocated according to rotation of a cam. The lifter body has a peripheral wall slidable in a sliding hole and a partition wall partitioning an inside of the peripheral wall into a first space where the cam is located and a second space located opposite the first space. The retainer has a retainer body connected to an engaging member and a rotation preventing protrusion protruding from an outer periphery of the retainer body and fittingly extending through the peripheral wall. The rotation preventing protrusion has a distal end moved into a rotation preventing groove to prevent the lifter body from rotation. The biasing member interposed between the retainer body and the housing to bias the lifter body to the cam side.

Abstract: 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.
Abstract translation: 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。
