Abstract: A pole device for a skiing contest comprises a cylindrical member to be embedded in a snow ground, a pole base member to be fitted into the cylindrical member and a pole portion fitted into the pole base member. The pole base member is formed with grooves extending in an axial direction thereof on an outer peripheral surface thereof and the cylindrical member is formed with projections at an inner peripheral surface thereof. Each of the projections has an outer shape to be fitted in the groove. The groove is composed of a first guide groove having an end portion through which the projection enters the groove, a second guide groove formed to be continuous to the first guide groove through a circumferintially shifted groove portion and a circumferential fitting groove formed at a portion near upper end of the pole base member to be continuous to the second guide groove.
