PURPOSE:To facilitate automatic assemblage when a shaft is fastened to a base material with bolts or nuts, by constituting a device for preventing the shaft from idle rotation from a one-way clutch for blocking the shaft from idle rotation, a brake device for preventing the shaft from idle rotation in bolting, etc. CONSTITUTION:A plurality of screw shaft support members 2 are rotatably planted on a base bed (pallet) 1 transferred on a conveyer, and an one-way clutch 3 is attached to a screw shaft 30 inserting portion on the respective members 2. A bearing bed 4 and a pushing-up spring 5 are built in the lower portion of the one-way clutch 3, and said clutch is formed on the lower end with gears 6. Also, on the base bed 1 are provided a gear 8 meshing with each gear 6 and rotatable around the shaft 9 and a brake device 7 held by this gear 8 and having a brake shoe 10 slidably contacting the upper surface of the base bed 1. And on a conveyer frame is provided an engagement releasing device to release the screw shaft 30 from the engagement with the one-way clutch 3 when a base plate 40 which has completed the fixation of the screw shaft 30 by a screw is released from the base bed 1. |
