A back kneading device capable of causing a massage mechanism to protrude forward and return to an original normal position is provided with no increase in size and complexity in construction. The back kneading device mounted in a chair massage apparatus includes the massage mechanism having a pair of right-hand and left-hand massage members, a base member for pivotally supporting the mechanism at its lower end, a vertical movement mechanism for imparting a vertical motion to the base member, an advancing and retracting mechanism for rockably driving the massage mechanism, and a rock restricting mechanism for an adjusting an angle of rotation of the massage mechanism so that, when the device is in an upper position, an upper end of the massage member protrudes forward, whereas, in a lower position, a lower end thereof protrudes forward.
