Summary:A shaftless fan structure having an axial air slit includes: a base, including a bottom plate connected with a fasten post; a rotor set, including a impeller sleeved on the fasten post and a magnetic member, wherein the impeller is formed with a bottom surface oppositely arranged with respect to the bottom plate, and the magnetic member is disposed on the bottom surface; a rolling bearing, fastened between the fasten post and the rotor set; and a stator set, disposed on the bottom plate and including a magnetic inducing portion oppositely arranged with respect to the magnetic member, wherein an axial air slit is formed between the magnetic inducing portion and the magnetic member. Accordingly, an objective of being shaftless is achieved, and the total height can be reduced through altering the arrangement of the magnetic member and the stator set.
