The invention discloses a miniature massager comprising a drive motor, an eccentric wheel, an upper shell, a lower shell and an enclosing shell. The eccentric wheel is fixed on an output shaft of the drive motor, and the upper shell and the lower shell are connected with each other through a connecting ring made of a soft material. The upper shell comprises a bottom part, a middle part and a top part; the bottom part and the middle part of the upper shell are fixed by screws, the top part is detachably fixed with the middle part, and accommodating holes are formed in the middle of the top part of the upper shell. Since the upper shell is composed of the bottom part, the middle part and the top part and the bottom part and the middle part are fixed by screws while the top part and the middle part are fixed detachably, installation and detachment are facilitated by means of screw fixing which is firm in effect; the middle part and the top part of the upper shell are fixed detachably so that detachment is facilitated; the accommodating holes of the top part of the upper shell are enclosed by the enclosing shell so that foreign matters such as dust are prevented from falling into the accommodating holes.
