滚子挺杆及其制造方法
摘要：
本发明提供一种能够抑制制造成本的增加的滚子挺杆及其制造方法。滚子挺杆(10)具有：挺杆主体(11)，其具有筒状的周壁(12)，且周壁(12)的外周的滑动面(21A、21B)在气缸(61)的内壁(62)上进行滑动；滚子(18)，其经由轴部件(16)而以能够旋转的方式被配置于挺杆主体(11)上，且与凸轮(90)接触。挺杆主体(11)具有使周壁(12)的一部分向外侧突出的形态的止转部(22)、和在周壁(12)上的与止转部(22)的径向相反一侧的部位处，以所述止转部(22)与之对置而面对面的方式开口的开口部(26)。
摘要（英）：

A roller lifter includes a lifter body (11) having a cylindrical peripheral wall (12) and a roller (18) rotatably mounted on the lifter body (11) via a shaft member (16) and brought into contact with a cam (90). The peripheral wall (12) has an outer periphery formed with a sliding surface (21A, 21B) which is slid on an inner wall of a cylinder (61). The lifter body (11) has a rotation stopper (22) formed by outwardly protruding a part of the peripheral wall (12), and an opening (26) formed in another part of the peripheral wall (12) which another part is radially opposed to the rotation stopper (22) . The opening (26) is open so that the rotation stopper (22) oppositely faces the opening (26).
