An upper body (10) having a display and a control unit installed at an upper end thereof and selectively operating a hatching mode according to a user's operation and having a heat ray member (28) for heating the surrounding air； A lower body 70 spaced at a predetermined distance from the lower portion of the upper body 10 and having a hollow disc shape and storing a plurality of eggs therein； A blowing fan 30 installed at a central portion of the upper body 10 for blowing the air heated by the heat ray member 28 downward； A rotary plate 42 installed at a lower portion of the blowing fan 30 and having a disk shape and having a plurality of teeth formed on a side thereof； a lower plate 42 protruding downward at the center of the rotary plate 42, The air blowing pipe 48 is formed at the lower end of the blowing pipe 48 and guides the heated air to the lower end of the air blowing pipe 48. The rotating force of the rotating plate 42 A driving member (40) composed of a power transmission rib (52) for transmitting the driving force； A driving motor 44 installed at one side of the rotation plate 42 and coupled to the rotation plate 42 to rotate the rotation plate 42； And an egg transfer member 60 installed at a lower portion of the driving member 40 and inserted into the power transmission rib 52 and rotated left and right according to the rotation of the rotation plate 42 . According to the present invention, the rotary plate and the blowing pipe are integrally formed, and the power transmission rib of the blowing pipe is gear-engaged with the full-shear member to rotate the full-shear member. Therefore, it is possible to reduce the material cost and the space utilization by reducing the number of parts by performing the blowing pipe to serve both as a rotary shaft and a blowing pipe without having to install a separate rotary shaft. In addition, since the air blowing fan, the air blowing pipe and the air blowing guide pipe are arranged in a line in the center of the inc
