PROBLEM TO BE SOLVED: To provide a walking stick with wheels which increases the mobility and stability and ensures the safety while being lightweight and compact and retaining the portability. SOLUTION: A main body is formed by connecting a wheel part sheath pipe and a walking stick part sheath pipe with joint pipes. A clutch supporting pipe is housed in the wheel part sheath pipe, and a pair of gripping part supporting pipes connected with a gripping part are mounted on the clutch supporting pipe and a walking stick part supporting pipe to extend and contract. Parts for producing greater friction are attached to the ends of both sheath pipes by attaching a clutch with the function of regulating rotations of a clutch arm and wheels below the wheel part sheath pipe and by hanging a bag on the joint pipes. The walking stick increases the mobility because of the wheels, and it enables stable walking easily without any action to hold up the walking stick and to bring the walking stick forward because of the wheels or the walking stick making contact with the ground all the time. Meanwhile, since the walking stick never moves by itself because of the regulated rotations of the wheels in one direction, a user never falls by being dragged by the walking stick.
