Abstract:
A jig for driving a closing cap (70) straight into a bolt installation hole (11)
bored in a track rail (1) and capable of repeating the driving work quickly for
bolt installation holes (11). The jig is constituted of a driving piston (73)
and a guide holder (72) for holding the driving piston (73) relative to the track
rail (1) with the piston set to a predetermined attitude. The driving piston (73)
has a pressing portion (75) in contact with the upper surface of the closing cap
(70) and also has a hammering portion (74a) hammered by a tool. The guide holder
has a cylinder (72a) in which the driving piston (73) slides. A guide groove (77)
is formed at an opening on one end side of the cylinder so as to perpendicularly
intersect the axial direction of the cylinder, and an upper portion of the track
rail fits with play into the opening. The guide holder is provided with an opening
(72b) for receiving the closing cap projecting on the track rail in the cylinder.
