    摘要： To provide a cab coming-off prevention structure of a working machine capable of preventing a coming-off prevention device from falling off.
    One end side of a stopper shaft portion 51 of a coming-off prevention device 16 is inserted through a through-hole 37a. The other end side of the stopper shaft portion 51 is inserted through an insertion hole 23b. A stopper main body portion 52 is provided on the other end of the stopper shaft portion 51. A portion of the key member 53 is fitted into a notched portion 51c provided along a direction crossing an axial direction of one end side the stopper shaft portion 51. The other part of the key member 53 protruding from the stopper shaft portion 51 is fixed to the one of the cab 14 and the revolving frame 23. Even if the key member 53 is disconnected from the cab 14 or the revolving frame 23, the coming-off prevention device 16 can be prevented from falling off, without the stopper shaft portion 51 coming off the through-hole 37a, because a portion of the key member 53 is fitted into the notched portion 51c of the stopper shaft portion 51.
