挺杆的止转结构
摘要：
本发明提供一种能够充分确保滑动方向上的长度并能够容易地实施成品加工的挺杆的止转结构。挺杆主体(20)具有：以能够往返移动的方式而被插入于壳体(91)的滑动孔(93)内并能在滑动孔(93)内滑动的周壁(21)、将周壁(21)内划分为凸轮侧空间(24)与卡合部件侧空间(25)的隔壁(23)。在挺杆主体(20)的卡合部件侧空间(25)内配置有具有与柱塞(80)等卡合部件连结的保持器主体部(61)的保持器(60)、安装在保持器(60)与壳体(91)之间并对挺杆主体(20)向凸轮(94)侧施力的施力部件(85)。保持器(60)具有从保持器主体部(61)的外周突出而嵌合贯穿周壁(21)、且顶端部(64)进入到壳体(91)的止转槽(96)内而抑制挺杆主体(20)的旋转的止转突部(63)。
摘要（英）：

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.
