Power generation device

A power generation device comprising, in a casing, an alternator that generates power through driving of an engine, an inverter case that houses an inverter of the alternator, and a fuel tank that stores fuel for the engine, the device comprising:

• an upper fixing part that fixes an upper part of the fuel tank to the casing,
• an intermediate fixing part that fixes a lower part of the fuel tank to an upper part of the inverter case, and
• a lower fixing part that fixes a lower part of the inverter case to the casing, wherein
• the intermediate fixing part comprises a lower fixing bracket provided in the lower part of the fuel tank, and a lower tank mount member attached to the lower fixing bracket and abutting on the upper part of the inverter case,
• the inverter case is configured to fasten and fix a front plate of the casing,
• the front plate, the lower fixing bracket, the lower tank mount member and the inverter case are fastened and fixed via a bolt,
• the intermediate fixing part is provided at a position shifted from the upper fixing part toward the front plate side,
• the upper fixing part is disposed rearward than a refueling cap of the fuel tank in a front-rear direction of the casing, and
• the power generation device is configured such that if external force is applied to a refueling cap part of the fuel tank from above, a direction in which rotation moment about the upper fixing part works coincides with an axial force direction of the bolt.
