PURPOSE:To eliminate play between a gear and a feeding screw and thereby to contribution to improvement of work efficiency in various processing and assembling work, by adapting a tension member connecting a sliding mount and a supporting plate to be biased so that the gear and a follower gear to pull each other. CONSTITUTION:A disk 1 on which a work or jig is fitted is fixed to a gear 6 through a rotatable shaft 5 and the shaft 5 is rotatably attached to a sliding mount 4. the sliding mount 4 is provided with sliding members 3 and sliding claws 2 provided on the top face at the end of the sliding members 3 receive the weight of the disk 1 and the force which is developed during the working period. In parallel with rails 9 are provided two feed screws 7, 8, which engage the gear 6 at its both sides, and a follower gear 10 is provided between the feed screws 7, 8. A tension member 14 is provided for connecting the sliding mount 4 and the supporting plate 12, which tension member 14 is adapted, upon its being biased, to cause the gear 6 and the follower gear 10 to pull each other thereby to eliminate the play between the feed screw and the gear 6. When the tension member is released from the bias, the gear 6 is rendered easily movable. |
