<P>PROBLEM TO BE SOLVED: To prevent a drawing knob portion from being erroneously used as a handle for allowing an operator to get on/off, in a cabin where the handle for allowing an operator to get on/off and the drawing knob portion for closing a door in a cabin are arranged in parallel. <P>SOLUTION: A crank-shaped portion 39 having a horizontal bending portion 38 extending horizontally in an opposite direction is formed in the upper part of a door frame 32 and at the rear of a rear handle 31 for allowing an operator to get on/off and in the portion diagonally upward relative to the handle 31. The space between the crank-shaped portion 39 and a door glass 33 is formed to have a large size with a grip margin to be grasped by hand, to thereby constitute a drawing knob portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
