The present invention relates to a shaft entry device for removing debris. The purpose of the present invention is to prevent a safety accident by removing debris without directly removing debris wound around an impeller shaft in a prow of a hull by a worker, wherein the shaft entry device for removing debris is configured to allow a worker to directly remove rope or net wound around an impeller or a driving shaft in the hull after a worker directly inspects an inspection window, installed on a jet room bottom of a hull, to confirm debris wound around a driving shaft or impeller, for example a net or rope. The shaft entry device for removing debris comprises: a ladder member which has one end fixed and installed to an inner surface of a manhole provided to inspect that debris, such as a net or rope, is wound around a driving shaft by welding by protruding to close an upper part through an opening and closing door formed on a bottom surface of a jet room of a hull, and has the other end inserted and discharged from one end by operation of the worker and provided to be inserted or discharged toward the driving shaft; a scaffolding installed on the other end of the ladder member to allow a worker to work with worker′s two hands while standing; and a ladder member inserting and discharging means having one end fixed to the scaffolding and the other end fixed to the inner circumferential surface of the manhole so that the ladder member is positioned in the manhole by inserting the other end of the ladder member to one end side when the work is completed.
