It is intended to provide a cooling structure for a bearing housing for a turbocharger, the cooling structure being configured so that the cooling structure is manufactured with improved productivity, the occurrence of heat soak-back is reduced, and the cooling structure has improved cooling performance. The cooling structure is configured to cool both a bearing housing 13 and a bearing 52 by cooling water flowing through an annular cooling water path 13f formed in the bearing housing 13, and is provided with: a water path inlet 13h for supplying the cooling water and a water path outlet 13j for discharging the cooling water, which are provided in the bearing housing 13 so as to communicate with the annular cooling water path 13f and a partial partition 14a in the bearing housing 13 to partially close a water path which forms the shortest route between the water path inlet 13h and the water path outlet 13j. |
