    • Provided is a driving jig for a closing cap which makes it possible to drive a closing cap straight into a bolt installation hole (11) formed in a track rail (1) and which allows this driving operation to be quickly repeated on a plurality of bolt installation holes (11). The jig includes a driving piston (73) and a guide holder (72) for maintaining the driving piston (73) in a predetermined attitude with respect to the track rail (1). The driving piston (72) has a pressing portion (75) coming into contact with an upper surface of the closing cap (70), and a hammering portion (74a) to be hammered by a tool. The guide holder has a cylinder (72a) in which the driving piston (73) slides, and has, at an opening at one end of the cylinder, a guide groove (77) into which an upper portion of the track rail is loosely fitted and which is orthogonal to an axial direction of the cylinder. The guide holder is provided with a receiving opening (72b) through which the closing cap protruding beyond the track rail is received into the cylinder.

    • The present invention provides a structure for closing a track rail mounting hole, which prevents a closing cap from being press-fitted with an inclined state into the rail mounting hole, thereby being capable of positively preventing formation of a gap between the rail mounting hole and the closing cap. The closing cap (70) includes: a fitting portion (71) having an outer diameter larger than an inner diameter of the rail mounting hole (11b), to be press-fitted into the rail mounting hole (11b); and a leading end portion (72) to be inserted into the rail mounting hole (11b) before press-fitting the fitting portion (71) into the rail mounting hole (11b), for provisionally positioning the closing cap (70) with respect to the rail mounting hole (11b). The leading end portion (72) is provided with a positioning protrusion (74), protruding from a periphery of the leading end portion (72) in a substantially triangular section to constitute a tip edge portion (75), the tip edge portion (75) having an outer diameter being set to be the same or slightly larger than the inner diameter of the rail mounting hole (11b).
    • 本发明提供一种用于封闭轨道安装孔的结构,其防止闭合盖被压配合到轨道安装孔中的倾斜状态,从而能够积极地防止轨道安装孔和 封闭帽。 封闭盖(70)包括:外径比导轨安装孔(11b)的内径大的嵌合部(71),压配合到导轨安装孔(11b)中; 以及在将嵌合部(71)压入轨道安装孔(11b)之前插入轨道安装孔(11b)中的前端部(72),用于将闭合盖(70)相对于 轨道安装孔(11b)。 前端部(72)具有定位突起(74),该定位突起(74)从前端部(72)的周围以大致三角形的部分突出,构成前端部(75),前端部 ),其外径被设定为与轨道安装孔(11b)的内径相同或略大。
