摘要： PURPOSE: To obtain a jig for inspecting a circuit board with minimized poor contact suitable for automation of an inspecting instrument by using a push having an inverted cone-shaped bearing hole, a centripetal body or the like having a tapered part expanding upward. CONSTITUTION: A centripetal body 5 supports a probe 9 to be mounted on an IC socket actually mounted on a circuit board to be inspected and a push 2 supports the centripetal body 5 with a mobile range limited. The centripetal body 5 is made up of a horizontal vibration oscillating means 4, a centripetal shaft 13 and a link member 20. The push 2 is provided with an inverted cone- shaped bearing hole 1 and a tapered part 3 is formed on the centripetal body 5 energized downward so that the centripetal body 5 points right downward from the center of the bearing hole 1 in a steady state. As a result, the direction of the probe 9 is fixed according to a relationship of a cam groove 6 and a cam follower 7. A fine deviation is corrected in the mounting of the probe 9 on the socket by generating vibration by the horizontal vibration generating means 4 while foreign matters or the like of a pin terminal are removed.
