PROBLEM TO BE SOLVED: To provide a shaft bearing structure of a rotary shaft of a crusher with which invasion of dust into a junction part can be suppressed and damage to a shaft bearing part due to invaded dust, or the like, can be prevented beforehand. SOLUTION: In the shaft bearing structure of the rotary shaft 5A of the crusher in which an axial center of a rotor 5, at a surface of which a crushing blade 5a is attached, is supported by freely rotating in a horizontal posture and a charged object to be crushed is crushed, an end part of the rotor 5 is inserted into a tubular frame 30, further the rotary shaft 5A of the rotor 5 is supported by a bearing 36 provided at a bearing housing 35 and a space S having a gap S2 being larger than a gap S1 that is formed by an end part peripheral surface of the rotor 5 and the tubular frame 30 arranged by facing it, is formed between an end face of the rotor 5 and an end face of the tubular frame 30 or the bearing housing 35.
