Abstract:
Provided are a suction control device and an endoscope capable of suppressing the clogging of a suction conduit. A first movable body (104) has a first connection hole (113) communicating with a suction source (5), a second connection hole (114) communicating with a suction port (34) of an endoscope (2), and a ventilation hole (115). The first movable body (104) is stored in a storage hole (103) of a housing (102) so as to be movable between a suction position enabling communication between the suction port (34) and the second connection hole (114), and a non-suction position. A second movable body (105) is supported by the first movable body (104) so as to be movable between an open position at which the ventilation hole (115) opens to the atmosphere, and a closed position. When the first movable body (104) is disposed in the non-suction position, the second movable body (105) is disposed in the open position, and when the first movable body (104) is disposed in the suction position, the second movable body (105) can be disposed in the open position or the closed position.
