PURPOSE:To smooth rotation of shaft and to reduce vibration and vibration noise by installing a balance weight to offset an eccentric load on the shaft the head end part of which eccentrically rotates. CONSTITUTION:This mechanism has an eccentric shaft 1c eccentrically provided on an head end part of a shaft 1, a bearing 2 integrally provided on the eccentric shaft 1c, a pin shaft vertically arranged against the shaft 1 free to revolve on the extension of the shaft 1 and an oscillating member arranged integrally on the pin shaft and having a recessed part 5a on the head end of which an outer race of the aforementioned bearing 2 is loosely fit, and it converts rotation of the shaft 1 to turning movement of a turning movement shaft 6. An object 15 is a balance weight provided on the shaft 1, and it smooths rotation of the shaft 1. It consists of the balance of the balance weight installed integrally on the shaft and to balance an eccentric load of the shaft 1. |
