摘要：
A projector includes a case, a lamp unit and a barrier mechanism. The case has a first ventilation opening for communicating an inner side with an outer side of the case. The lamp unit is disposed in the case. The lamp unit includes a housing and a lamp body disposed in the housing. The housing has a second ventilation opening for communicating an inner side with an outer side of the housing. The barrier mechanism is disposed on a path from the second ventilation opening to the first ventilation opening. The barrier mechanism includes a first barrier member and a second barrier member. The first barrier member has a first receiving plate facing the second ventilation opening. The second barrier member has a second receiving plate disposed apart from the first receiving plate in a first direction to the second ventilation opening and disposed offset from the first receiving plate in a second direction crossing the first direction.
