Abstract: An annular seal assembling jig 1 is used when assembling an annular seal 3 to a spherical body 2 of a ball joint. The jig 1 is equipped with a plurality of split tables 7 which constitutes one table 6, a slider 5 fixed to the split table 7 and is capable of sliding freely along a guide rail 5a, a coil spring 82 which biases the slider 5 to the other split table 7 side, and a claw portion 72a provided to each split table 7, so as to catch the annular seal 3 placed on the table 6, from an inner side of the annular seal 3.

Abstract: In a workpiece feeding apparatus having a rotating shaft adapted to rotate to separate and individually feed a plate-like workpiece suspended side by side in an axial direction along a helical region formed on an outer peripheral surface of the rotating shaft and drop the plate-like workpiece from an edge thereof and a motor rotating the rotating shaft, the rotating shaft includes a first rod connected to the motor, and a second rod rotatably connected to the first rod and having a helical region formed on the outer peripheral surface of the second rod and a workpiece hanger at the edge to extend perpendicular to the axial direction and to be bent at a distal end, such that the second rod stops rotating when the workpiece is hung from the distal end of the workpiece hanger.
