Abstract: A tip tool mounting structure for a machining device includes a shaft portion and a holding member. The shaft portion includes a ridge extending in a longitudinal direction and projecting outward in a radial direction. The holding member includes a protrusion projecting outward in the radial direction, switches between an attached and detached state and a fixed state by the rotation, the holding member is configured to be temporarily fixed in the attached and detached state, the attached and detached state is a state in which the protrusion overlaps with the ridge in the longitudinal direction, and the fixed state is a state in which the protrusion does not overlap with the ridge in the longitudinal direction. The temporary fixation of the holding member is automatically released by a movement of a tip tool to an opposite distal end side in the longitudinal direction.
