Abstract:
To provide a cooling passage structure capable of inhibiting damage caused by heat stress.SOLUTION: A cooling passage structure includes: a first wall part extending along a first direction; a second wall part which is disposed spaced apart from the first wall part in a second direction orthogonal to the first direction; and partition wall parts which connect the first wall part with the second wall part so as to form at least one cooling passage having passage cross sections, which are disposed spaced apart from each other in the first direction, between the first wall part and the second wall part. On a cross section including the first direction and the second direction, the first wall part includes a thin portion having a thickness smaller than a thickness t1 at a position spaced apart from the partition wall part in the first direction when a thickness of the first wall part at a position, where a second wall part side surface of the first wall part and a surface of the partition wall part are connected, is referred to as t1.SELECTED DRAWING: Figure 2
