Abstract
A general-purpose engine includes a canister for adsorbing fuel vapor that has evaporated within a fuel tank. The fuel vapor, which has desorbed from the canister, is guided to an intake system communicating with an engine main body. A housing recess is formed in a base of the fuel tank, recesses toward the interior of the fuel tank, and houses the canister. Thus, an external impact to the canister can be avoided while also avoiding any increase in the dimensions of the general-purpose engine.
