Abstract

A portable massaging device comprises a cylindrical body in which a power unit is housed and over which a massaging set is fitted. The power unit is composed of a motor, a battery set, a cam and a conducting member. The massaging set is composed of a plurality of fitting members and massaging nipples. The fitting members are provided respectively with a plurality of receiving recesses in which the massaging nipples are held. The fitting members are further provided respectively in the connection ends thereof with a plurality of mortises and tenons, by way of which the fitting members are held together. An end cap is fastened to one end of the cylindrical body for locating the massaging set and for shielding the power unit. A handle is fastened at one end thereof with the end cap and at another end thereof with the conducting member.

Claims
