A ball type massager comprises a left shell (100), a right shell body (100), a connector (200) connected with the two shells (100), massage components (300) arranged in the inner surfaces (110) of the shells (100) and motors (400) set in the shells (100) and used for driving said massage components (300) to rotate. The massage components (300) include rotating plates (310) and multiple massage heads (320) disposed on the rotating plates (310), wherein the rotating plates (310) are embedded in the inner surfaces (110) of the shells (100) and driven to rotate by the motors (400). The massage heads (320) comprise spherical concave cavities (321) set on the rotating plates (310) and rotatable elastic balls (322) placed in the spherical concave cavities (321). The elastic balls (322) protrude from the spherical concave cavities (321). The massager is provided with multiple massage heads (320) on the rotatable rotating plates (310), which increases the area of the massage. At the same time, as the direct action parts of the massager, the elastic balls (322) are pushed to roll by friction force during massage and ball massage is realized which achieves a good massage effect. Because the elastic balls (322) are made of elastic material, the elastic balls (322) can be freely removed or placed in the spherical concave cavities (321).La présente invention concerne un dispositif de massage à balles comprenant une enveloppe gauche (100), un corps denveloppe droit (100), un connecteur (200) relié aux deux enveloppes (100), des éléments de massage (300) placés sur les surfaces internes (110) des enveloppes (100) et des moteurs (400) disposés dans les enveloppes (100) et utilisés pour entraîner lesdits éléments de massage (300) et les faire tourner. Les éléments de massage (300) comprennent des plaques tournantes (310) ainsi que de multiples têtes de massage (320) disposées sur les plaques tournantes (310), les plaques tournantes (310) étant intégrées dans les surfaces internes (11
