PURPOSE:To keep off any damage attributable to a handle in time of falling, by making a clearance between a shaft and a hole inside bottom wider than that between the peripheral wall of a cylinder part for shaft fitting use and an apparatus body. CONSTITUTION:In case of a cylinder part 7 having a hole 6 for fitting a shaft of a handle 5 and this handle having a peripheral wall surrounding the cylinder part, a tappet 9 is set up on the inside bottom of the hole, and a lateral hole 12 is formed in the cylinder part 7, while a slit 10 is installed at least in a more upper part than this lateral hole 12, inserting a shaft 13 for control use into the cylinder part 7, and likewise inserting a knock pin 11 into the lateral hole 12, and a clearance l2 between a shaft 3 end and a hole inside bottom 9 is made larger than that between a peripheral wall 8 and a machine body 1. Doing like the above, when a handle device suffers an impact, protection for an adjusting mechanism part is promoted, thus preventing the machine body from being damaged by the handle. |
