Shielded window structure of a numeral lock. A window member is disposed on one side of the housing of the lock. The window member is formed with a row of windows through which the numerals of a row of numeral wheels are shown. The linking member is drivingly connected with an internal driving plate for driving internal components to control locking/unlocking of a hook member at one end of the housing. The window member is synchronously horizontally displaceably or deflectably connected with the linking member. When moving the linking member to unlock the lock, the window member is synchronously displaced to disalign the windows from the unlocking number of the numeral wheels so as to shield the unlocking member and prevent an unauthorized person from seeing the unlocking number.
