A G-shaped kneading massage mechanism having a massage head capable of a push-press motion is provided with a slide rail fixing board (5). A vertical slide rail (3) having a mating slide block (4) thereon is fixed to a left surface of the slide rail fixing board (5). A massage rod (2) having an upper end capable of being connected to a massage head (1) is installed on the slide block (4). An electric raising/lowering mechanism is disposed on the left surface of the slide rail fixing board (5). The electric raising/lowering mechanism has a raising/lowering member connected to the slide block (4), and a bottom thereof is connected to a push board (6). An electric push-press mechanism (10) is installed on a connecting board extending in a left direction at a lower portion of the slide rail fixing board (5). The connecting board or a mount of the electric push-press mechanism (10) is connected to a lever (7) via a lever pivot pin (7-1). A cam wheel (11) connected to an output shaft of the electric push-press mechanism (10) pushes and presses against one end of the lever (7). The other end of the lever (7) pushes and presses against the push board (6) below the electric raising/lowering mechanism. The massage mechanism is applicable to human body massage, can exert a constant force, and has favorable functions.Linvention concerne un mécanisme de massage par pétrissage en forme de G, comportant une tête de massage capable dun mouvement de pousser-presser, et qui est pourvu dun panneau de fixation pour glissière (5).
