PROBLEM TO BE SOLVED: To allow simultaneous unlocking at right and left sides and lifting operation of a front window when opening the front window in a construction machine to be opened with a series of operations. SOLUTION: In a construction machine cab which has this front window 5 movable via a guide slidably guided and supported along a guide rail ranging from the front side of a cab body to a ceiling side, locking mechanisms 10 for the cab body are provided on the right and left sides at the upper part of a window frame 6 of the front window 5 and an unlocking lever 20 simultaneously operable with a hand gripping a window opening/closing handle 8 is provided at the upper part of the window frame 6. The unlocking lever 20 and the right and left locking mechanisms 10, 10 are connected via a relay member 16 so that the right and left locking mechanisms 10, 10 may be simultaneously unlocked when the unlocking lever 20 is pulled by using connection members (rods 25, 26).
