被保持部件的临时固定件以及保持件
摘要：
本发明的课题在于防止保持件从螺柱脱离。在螺柱(30)的棒状部(31)设置有：螺纹加工部(31A)，其形成有螺纹槽；以及非螺纹加工部(31B)，其未形成有螺纹槽，在非螺纹加工部的螺纹加工部侧端部形成有：非螺纹加工扩径部(31b3)，其朝向形成有螺纹槽的螺纹部的螺纹牙而外径扩大；以及非螺纹加工小径部(31b2)，其与非螺纹加工扩径部的小径部位连接、且直径与该小径部位的直径相同。在保持件设置有对棒状部进行收纳的螺柱收纳孔、以及第一卡止部和第二卡止部。在固定保持状态下，第二卡止部与非螺纹加工小径部卡合，在保持件向从上述固定保持状态脱离的方向移动了规定量的状态下，第二卡止部与非螺纹加工扩径部卡合。
摘要（英）：

A threaded portion with thread groove formed and non-threaded portion without the thread groove are prepared on rod-like portion of stud, and non-threaded diameter-increasing portion whose outer diameter is increasing toward thread ridge of screw portion with thread groove formed and non-threaded small diameter portion connecting to small diameter region of non-threaded diameter-increasing portion and having same diameter as that of small diameter region are prepared at threaded portion side edge of non-threaded portion. A holder is provided with stud-receiving hole which receives the rod-like portion, a first locking portion and a second locking portion. The second locking portion is engaged with the non-threaded small diameter portion in a fixedly holding status, and the second locking portion is engaged with the non-threaded diameter-increasing portion in a status that the holder is moved for a predetermined amount in a direction away from the fixedly holding status.
