PROBLEM TO BE SOLVED: To provide a lock structure of a slide bar body, which has a simple structure, enables the bar body to be securely in a lock state, and is extremely easily unlocked. SOLUTION: A circular insertion hole 3 is formed in a base 1 and the bar body 2 with a circular cross section having a diameter slightly smaller than a hole diameter of the insertion hole 3 is slidably inserted into the insertion hole 3. A support part 4 is formed around the insertion hole 3. A lock ring 5 provided with a through hole 6 which communicates with the insertion hole 3 and has the same shape as that of the insertion hole 3 is rotatably supported on the support part 4. By rotatably operating the lock ring 5 relative to the support part 4, a shape of either one of the support part 4 and the through hole 6, or both shapes of them are set in such a way that positional relation between the through hole 6 and the insertion hole 3 is changed from a positional relation allowing center of the through hole 6 to coincide with center of the insertion hole 3 to a positional relation allowing the center of the through hole 6 to be in an eccentric position relative to the center of the insertion hole 3.
