A structurally compact massaging machine core comprising a housing (1), a massaging element, a massaging motor (2), a transmission apparatus, and an electric control apparatus. The transmission apparatus comprises a first transmission mechanism used for driving the massaging element to perform kneading massage and a second transmission mechanism used for driving the massaging element to perform tapping massage. The electric control device controls the massaging motor (2) to make forward rotations or reverse rotations. The first transmission mechanism and the second transmission mechanism are both transmissively connected to the massaging motor (2). A one-way bearing (20) is arranged in the second transmission mechanism. When the massaging motor (2) makes forward rotations, the one-way bearing (20) slips forward to cut off a kneading transmission link, and the massaging element performs only kneading massage when the massaging motor (2) makes reverse rotations, the one-way bearing (20) locks in reverse to link up the kneading transmission link, and the massaging element simultaneously performs kneading massaging and tapping massage. The massaging machine core has the advantages of being structurally compact, easy to install, and great in massaging effects.Linvention concerne un noyau structurellement compact de machine de massage, comprenant un boîtier (1), un élément de massage, un moteur de massage (2), un appareil de transmission, et un dispositif de commande électrique.
