<p>PURPOSE:To have each connector in a series of connectors of a running board which are transferred with the postures of their connection pins kept horizontal run over an inclined hanging pulley by a method wherein the connection pin is automatically turned so as to make the connection pin parallel with the center axis of the hanging pulley. CONSTITUTION:A pair of rollers 3 are symmetrically provided on the left and right sides of the upper plane of a cylindrical main part 1 with a bearing metal fitting 2 therebetween. In a conventional constitution, only the cylindrical main part is provided and a turning force is applied to the outer circumference of the cylindrical main part with its center axis as the center of the turn. On the other hand, in this constitution, the center line of a large diameter imaginery cylinder enveloping the cylindrical main part 1 and both the rollers 3 is the center of turn and the turning force is applied to the outer circumference of the imaginery cylinder, so that a turning torque can be increased.</p> |
