Abstract

Abstract A borescope apparatus having a borescope and a pressurized fluid supply device. The borescope has an operation unit and an insertion unit. The insertion unit comprises a bending tube portion, a jet port member coupled to a proximal end of the bending tube portion, and a flexible tube portion. The bending tube portion can be bent by operating the operation unit. The jet port member has a jet port. A pressuring fluid is supplied from the fluid supply unit to the jet port member, and is ejected through the jet port. The flexible tube portion can be bent by a jet of the fluid from through the jet port independently of the bending tube portion.
