A vaporized fuel processing device comprising:

• a piping portion which constitutes a portion of a purge passage that causes an intake system of an engine mounted in a vehicle and a canister to communicate with each other, the piping portion having flexibility;
• a bracket fixed to the engine, the bracket including a support wall portion protruding in a direction away from the engine, and the support wall portion including a hole;
• and
• a check valve disposed in the piping portion, the check valve including a pawl portion configured to be engaged with the hole, and a support portion configured to support the check valve such that the check valve is suspended by the bracket, wherein:
• the support wall portion includes an edge portion protruding away from the engine beyond a position where the check valve is supported;
• and
• the pawl portion is configured to elastically deform to an extent that the pawl portion is disengaged from the hole when the support portion is inclined toward the engine in a state in which the pawl portion is engaged with the hole.
