Abstract: A rocker arm includes a pair of sidewalk disposed along a heightwise direction so as to be opposed to each other. The sidewalk 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 rocker arm includes a roller, a support shaft coaxially mounted in the roller and having a first end portion and a second end portion, walls including at least a first wall and a second wall arranged along the rotation axis and opposite each other with having the roller therebetween, the first wall having a first through hole through which the first end portion is inserted and the second wall having a second through hole through which the second end portion is inserted, and plate portions including at least a first plate portion and a second plate portion arranged opposite each other with having the first wall, the second wall and the support shaft therebetween. The first plate portion is in contact with a first end surface of the first end portion and the second plate portion is in contact with a second end surface of the second end portion.

Abstract: A lash adjuster includes a body, a plunger which is inserted into the body and has 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 the body, and a partitioning member inserted into the plunger. The partitioning member has 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 inside. The low-pressure chamber reserves 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.

Abstract translation: 间隙调节器包括主体，柱塞，其插入到主体中并且具有带有阀孔的底壁和具有油通道孔的周壁和形成有凹槽的内周，柱塞限定高压 在底壁和主体之间的腔室以及插入柱塞中的分隔构件。 分隔构件具有位于油通孔上方的油路端。 分隔构件具有与凹槽相对设置的油通道限定部分，并且在其自身和凹槽的凹槽面之间限定油通道。 分隔构件在内部限定低压室。 低压室保留流过油通孔，油路和油路端的液压流体。 低压室使保留的液压流体通过阀孔流入高压室。
