POWER SOURCE PROTECTION STRUCTURE

[PROBLEMS] The present invention provides a protecting structure for a power source apparatus capable of suppressing the action of an external force on the power source apparatus when a vehicle is subjected to a shock. [SOLVING MEANS] A protecting structure for a power source apparatus, has a frame unit in which a plurality of frames (21a to 21h) are connected to each other and surround the power source apparatus (30) mounted on a vehicle; and an abutting member (22) connected to the frame unit and extending in a direction in which the abutting member abuts on a vehicle body. The abutting member is arranged so as to extend in a direction in which an external force in a predetermined direction acts on the vehicle.
