PURPOSE:To obtain a single rotation clutch where the shock at the start/stop is relieved while employing the lowest speed highest torque position as the stopping point during one rotation of the output shaft to stop accurately at the fixed position. CONSTITUTION:A stopper arm 19 is rolled through the operation of a cylinder 14 to disengage between a projection 12a of an inverted flange 12 and the tip 19a of arm while to roll the roll arm 22 around the shaft 21 through a coupling rod, then a pair of nail chips in a nail mechanism 8 are opened to gear with the inner gear 7a of a ratchet wheel 7. Consequently a drive arm 9 is rotated through the rotation of the ratchet wheel 7 to be rotated by the input shaft 1 through gear rows 3, 4. Consequently a roller R1 fitted to a guide groove 9a of the drive arm 9 will revolve, and the output shaft 10 integral with the inverted flange 12 will perform the intended movement and after one rotation said projection 12a will engage with the stopper 24 to be stopped. |
