A kind of ball massager is combined in one with a cap and is covered, and assembles the bead of an elastic component, a movable valve and one or more therebetween. The cap has multiple hole of beads, which forms the ball-and-socket of identical quantity at the hole of bead, and each ball-and-socket has a discharge hole, and bead is allowed to be placed in ball-and-socket and can roll. With elastic component drive movable valve support bead locally expose cap the hole of bead, using bead closing ball-and-socket as normality. In rolling massage, each bead unbalance stress, the ball-and-socket and bead of related movable valve causes raw gap, and liquid is facilitated to be applied on a body surface with the bead of rolling.一種滾珠按摩器,用一帽蓋結合一中套,二者之間組裝一彈性件、一可動閥及一顆或以上的珠體。該帽蓋有多個珠孔,該可動閥面對珠孔處形成相同數量的球窩,每個球窩有一出料孔,允許珠體置入球窩而可滾動。用彈性件驅使可動閥托著珠體局部露出帽蓋的珠孔,以珠體封閉球窩為常態。在滾動按摩時,各珠體受力不均,連帶可動閥的球窩與珠體致生間隙,方便液體隨著滾動的珠體塗抹在一物體表面上。
