To make both right-handed and left-handed persons able to continuously adjust the length of a stick with the same excellent operability.

In the stick for which a lower pipe 4 is freely slidably fitted and inserted inside an upper pipe 3, screw bodies 5 provided on both ends of a screw shaft 10 are fixed to the upper end of the lower pipe 4 so as to make the conical peripheral surfaces 8 of two upper and lower conical bodies 9a and 9b provided with the conical peripheral surfaces 8 face each other, and a cylindrical braking member 6 provided with spreading elasticity in a peripheral direction is screwed to the screw shaft 10 of the screw bodies 5. Then, by spreading the braking member 6 on the conical peripheral surfaces 8 of the upper or lower conical bodies 9a and 9b by turning the lower pipe 4 and bring it into press contact with the inner peripheral surface of the upper pipe 3, the upper pipe 3 and the lower pipe 4 are fixed.
