PURPOSE:To dispense with a special driving source and simplify the composition by making an assembling jig on a turntable reversible through utilizing a turning a turning effort of the turntable in a reversal device specially used for pushing an end stone by pressure into a bearing of a level meter. CONSTITUTION:When an assembling jig 14 supporting a level meter bearing comes to a bearing reversal station due to rotation of a turntable 2, an impeller 13 of said jig 14 is released from rotation control by a disc 8 correspondingly to a notch part 15 of the disc 8 provided on the turntable 2, then the impeller 13 strikes on reversal pin 19 installed on the disc 8 to be rotated by about 90 deg. With further rotation of the turntable 2, the impeller 13, after separation from the reversal pin 19, makes contact with an edge face of the notch part 15 of the disc 8 and is rotated by 90 deg. to put a shaft 12, with a retaining click 11 of the assembling jig 14, in rotation by 180 deg.. This results in the same effect as that of reversal of the bearing. After this reversal, two points of the impeller 13 make contact with the under surface of the disc 8 and the impeller is conveyed maintaining a definite angle with the disc. |
