PROBLEM TO BE SOLVED: To provide a sunshine-blocking case shading cover that can be easily fitted to an aggregation device fixed to a power pole or the like via a metal fitting.SOLUTION: A case shading cover 1 for protecting from light an aggregation device C fixed to a power pole P via a bracket A comprises a deformable seat 2 that can cover the outer circumference of the aggregation device C and of the bracket A fixing the aggregation device C and spacers 3 so arrayed on one facial part of the seat 2 as to be convex relative to the facial part of the seat 2. When the seat 2 is shaped as a cylinder and caused to so cover the outer circumference of the aggregation device C and of the bracket A that one facial part of the seat 2 comes inside, the spacers 3 come into contact with the aggregation device C and the bracket A to form a space among the seat 2, the aggregation device C and the bracket A.
