PROBLEM TO BE SOLVED: To provide a strong bar screen rake-shaped trashrack rake with very fine mesh. SOLUTION: Bar screens for fine mesh integrated with each other by screen passing bolts 15 are formed into an upstream side bar group 3, a downstream side bar group 4 integrated with each other by bolts used in common with the screen passing bolts 15 are alternately interposed in the bar clearances, and a downstream end of the upstream side bar and an upstream end of the downstream side bar are interposed in a not-overlapping manner in the stream direction, and the upstream and downstream side bar groups 3 and 4 can be formed firm while forming very fine mesh by the downstream end angle of the upstream side bar, the upstream end angle of the downstream side bar, and the clearance therebetween.
