A shutter type guard apparatus composed of a movable guard member which can be opened and closed for covering the window portion of the cab of a piece of machinery. The guard member is structured so that it can be closed to an intermediately opened position where it is easily operated. An auxiliary closing device includes a cable winding device for winding the first cable, a travelling unit coupled between the first cable and a second cable, an auxiliary guide rail in which the travelling unit and the first and second cables are guided for movement, and a pull handle coupled to the second cable. The auxiliary guide member is at one of a pair of left and right guide rails, for guiding the movable guard member. The pull handle is disposed at an intermediate position, in the vertical direction of the guide rail, and by pulling the pull handle downward, the guard member is forcibly closed to an intermediately opened/closed position where it can be easily reached and further closed by hand by an operator.
