The present invention relates to a thrust shaft protecting device for a water jet ship, capable of preventing a thrust shaft from being bent by preventing a rope or a net coming into an inlet of an inflow duct from being wound on the thrust shaft in a stern tube as the thrust shaft is rotated to generate thrust by having an end welded with the floor surface of a jet chamber; and having an other end placed in an extended line with the stern tube connected to a water seal. To achieve this purpose, the present invention comprises: a thrust shaft protecting material formed into a cylindrical hollow pipe to prevent the rope or net from being wound on the thrust shaft in the stern tube as the end is welded with the floor surface of the jet chamber, and the other end is placed in the extended line with the end of the stern tube connected to the water seal.
