PROBLEM TO BE SOLVED: To inexpensively provide a synthetic resin grating easy in assembling without the need for connecting a large number of synthetic resin pipes by a large number of connecting members and an end cap. SOLUTION: This grating is composed of a plurality of blocks 1 formed in a plurality of mutually parallel cross-sectional substantially inverse Y shape and made by using a synthetic resin as a material so that a main bar 3 having a horizontal part 2 on the upper end is connected at an equal interval by a connecting part 4, and a joint member 10 for connecting the these adjacent blocks 1 and 1 to each other. The main bar 3 of the end of the mutually connected one block 1 and the main bar 3 of the end of the other block 1 are made closely adjacent to each other, and the joint member 10 is positioned between proper places in the longitudinal direction between these main bars 3 and 3. The blocks 1 and 1 are connected to each other by locking a claw 11 of an insertion part 12 on the upper side of a locking part 7 of a groove 6 of the main bar 3 by inserting the insertion part 12 of the joint member 10 from the groove 6 formed of the lower end of the main bar part 3.
