A pipe handle holding structure wherein force for holding a bar handle in a holder is minimized, the holding performance whereby the bar handle is held by the holder is improved, and the bar handle and holder are maintained in an appropriate state even in cases in which the bar handle is frequently attached to and detached from the holder. The pipe handle holding structure (20) comprises a round pipe-shaped bar handle (17), and a holder (50) for holding an external peripheral surface (17d) of the bar handle. The holder has a plurality of concealing parts (72L, 72R) for concealing the external peripheral surface of the bar handle and elastically deforming the external peripheral surface in a pipe diameter direction.
