To prevent agitation blades from colliding with each other, regarding a hand mixer having agitation blades.

A pitch between the bearings 26a of a gear presser 26 is made smaller than a pitch between the bearings 25a of a gear carrier 25. As a result, when agitation blades 29 tend to vibrate laterally, the external surface 24a of the lower shaft part of a gear 24 comes in contact with the internal surface of the bearing 25a of the gear carrier 25 where a rotation shaft 22 exists, and the external surface 24b of the upper shaft part of the gear 24 comes in contact with the internal surface of the bearing 26a of the gear presser 26 at a position off the rotation shaft 22, thereby preventing the vibrations of the agitation blades 29 toward the intersection thereof.
