The present invention is a machine unit for a massager, whereby the structure of a mechanism portion for supporting shafts pertaining to tilting of a drive part for actuating a massaging element can be endowed with increased strength and made resistant to deformation while being simplified, and linkage of mechanism components can be maintained. A configuration is adopted whereby both end parts of each of a tilt shaft 22 for bearing a drive part 50 and a rotary shaft 23 relating to tilting of the drive part 50 are supported by two independent base frames 25, 26, and the size of an inclination at a right angle to the tilt shaft 22 and the rotary shaft 23 in the base frames 25, 26 as well as an inclination corresponding to the front-rear direction of a backrest part, is larger than the size of an inclination parallel to the tilt shaft 22 and the rotary shaft 23, whereby the base frames 25, 26 do not deform and the positional relationship between the tilt shaft 22 and the rotary shaft 23 is maintained even in a condition in which the base frames are subjected to a force acting to change the positional relationship between the tilt shaft 22 and the rotary shaft 23 from the drive part 50 side, linkage and interlocking of the mechanism components are kept in an appropriate state, components are not subjected to abnormal force and damage to components can be prevented, and the reliability or stability of massager operation is enhanced.Linvention porte sur un outils pour appareil de massage, grâce auquel la structure du mécanisme de support dinclinaison des tiges est dotée dune résistance accrue, rendue résistante à la déformation tout en étant simplifiée, et en maintenant la liaison des composants du mécanisme. Les deux extrémités dun axe dinclinaison (22) de support dune commande (50) et dun axe rotatif (23) par rapport à linclinaison de la commande (50) est maintenue par deux cadres de base indépendants (25, 26).
