Zusammenfassung:	To provide a cooler of a vehicular battery pack in which a cooling blower can be reduced in capacity and reduced in size.SOLUTION: In a cooler of a vehicular battery pack that is configured to cool a battery pack 3 with air by introducing air into the battery pack 3 provided at a lower surface side of a floor of a vehicle 1 and exhausting the air, air flow paths 5 through which air flowing from a front side toward a rear side generated by travelling of the vehicle 1 is distributed are provided at the lower surface sides of the floor, narrowed parts 6 whose flow path cross section areas are narrowed to increase flow speed of air are provided in the air flow paths 5, and further communication pipes 8 through which the inside of the battery pack 3 is communicated with the narrowed parts 6 to guide air inside the battery pack 3 to the narrowed parts 6 are provided in the paths.SELECTED DRAWING: Figure 2 【課題】冷却用ブロアを小容量化、小型化することのできる車両用電池パックの冷却装置を提供する。【解決手段】車両１のフロアの下面側に設けられた電池パック３に空気を導入しかつ排気することにより空気によって電池パック３を冷却する車両用電池パックの冷却装置であって、車両１が走行することによって生じる前方から後方に流れる空気を流通させる空気流路５がフロアの下面側に設けられ、空気流路５に流路断面積が絞られて空気の流速を増大させる狭窄部６が設けられ、電池パック３の内部と狭窄部６とを連通して電池パック３の内部の空気を狭窄部６に導く連通管８が設けられている。【選択図】図２
