Abstract
An expansion and contraction type guard baton causing less rattling or deviation even after repeating use and free from the worry of slipping off by the force of thrusting and extending the baton main body even if the wall thickness is decreased to reduced the weight. A plurality of cylindrical members are combined in a telescopic manner in which the conically inclined surface at the top end of an outer cylindrical member and a conically inclined surface at the rear end of an inner cylindrical member are engaged for preventing slip-off upon extension. The circumferential cylindrical slide guide surface in parallel with the cylindrical axis formed before and after the conically inclined surface and the cylindrical member are put to a plane-to-plane contact, thereby preventing rattling or deviation. Further, the wall thickness at the top end of the outer surface of the outer cylindrical member is increased to prevent slip-off.
