PROBLEM TO BE SOLVED: To provide a structure to be set, particularly, in a side-ditch of a sports ground or the like, which never injures a player even if he vigorously bumps on it with falling and can ensure the draining of the ground as a dust guard grating. SOLUTION: This dust guard grating is formed of a plurality of cushioning bars 2 consisting of a rubber or soft plastic cushioning material 4 and a hard core body 5 buried therein and a pair of frames 3 engaged with both ends of each cushioning bar 2 to retain the cushioning bars 2 in parallel at prescribed intervals.
