A leg massage unit is provided which comprises a calf massage unit made tiltable and/or upwardly or downwardly slidable and which is thereby adapted to give an improved massage effect to the user. The leg massage unit comprises a foot massage unit (10) for massaging the feet of the user, and a calf massage unit (80) tiltably coupled to the base end of the foot massage unit (10) by a connecting mechanism (90) and adapted to massage the calves of the user. The connecting mechanism (90) exerts torque acting to move the calf massage unit (80) toward an upright position relative to the foot massage unit (10). The connecting mechanism (90) also couples the calf massage unit (80) to the foot massage unit (10) upwardly or downwardly slidably relative to the unit (10).
