Working machine

摘要

A working machine has a machine room cover (15) and a bonnet (50) on an upper rotating body (2). The bonnet (50) has a frame-like raising member (51) and a dome-like hood member (52) that covers an opening in the upper part of the raising member (51). The lower part of the raising member (51) is attached so as to surround an opening portion (35) formed in the upper surface of the machine room cover (15), and the hood member (52) is attached to the raising member (51) so as to be able to be rotationally opened and closed.
