Provided is a cooling grate of a cooler apparatus, the cooling grate being capable of suppressing variation in passing pressure loss of cooling air. A cooling grate 1 includes a plurality of support plates 24 and 25 and a plurality of covering members 23. The support plates 24 and 25 are arranged in a conveying direction at intervals such that slits 27 are formed therebetween, the slits 27 allowing the cooling air to pass therethrough. Clinker bed 14 lies on the support plates 24 and 25. The support plates 24 and 25 include placement portions 28 extending along the entire slits 27 and positioned at both sides of the slits 27 in the conveying direction. The covering members 23 are placed on the placement portions 28. Each covering member 23 includes a tapered portion 23a, and is formed to have a V-shaped cross section. Each covering member 23 is placed on the placement portions 28 in a state where a plurality of spacers 22 are interposed between the tapered portion 23a and the placement portions 28, such that each covering member 23 covers an entirety of a corresponding one of the slits 27 from above. The plurality of spacers 22 are arranged in an orthogonal direction at intervals.
