PURPOSE:To enable the travel of a conveying supporter to vary within a wide range according to the change of a space between working positions, by equipping radially displaceably an arm mounted to an intermittent rotating shaft of a roller spider with a block one end of which is connected to an actuation lever. CONSTITUTION:In the parallel index driving apparatus C comprising a parallel cam shaft 1 having two cams 2, 3, and an intermittent rotating shaft 4 having a roller spider 20 that is intermittently rotated by the cams 2, 3, the apparatus C is driven by a motor M, a swingable lever i at one end of a shaft j for vertically moving object conveying supporters a, b, c is connected via a lever 5 to one end 61 of a lever bar 6 whose other end 62 abuts on another cam 7 on the shaft 1. One end 82 of a lever 8 whose other end 81 is connected to one end of the actuation lever d for horizontally reciprocating the supporters a, b, c is connected to the block 12 displaceable radially of the arm 9 provided on one end of the shaft 4. |
