A pair of left and right rotating shafts 7, 7 are bent to form a pair of left and right rotating shafts 7, and their inclined shaft portions 7b (crank tips) are connected to the housing 1.
A kneading ball 9 is provided on the inclined shaft portion 7b (crank tip portion) so as to protrude from the top plate.
In more detail, both the massaging balls 9, 9 are movably crowned together, and the massaging balls 9, 9 are oscillated and rotated in relative directions through the rotation of both rotating shafts 7, 7. Both massage balls 9, 9 massage the affected area through the oscillating rotation of
A massaging machine has previously been proposed in which a massaging machine is provided to obtain a massaging effect by grasping the material between the two. In the above-mentioned massaging machine, a massaging ball cover is usually placed between the top plate and the massaging balls, but in the past, a massaging ball cover was attached between the top plate and the massaging balls of the housing. As shown in FIG.
3 is recessed, and by screwing together the fixing screws 25 with the ends of the massaging ball cover 22 sandwiched between the mounting recess 23 and the holding plate 24, the connection between the mounting recess 23 and the holding plate 24 is A method was used in which a massaging ball cover 22 was sandwiched between the balls.

[Problem that the invention attempts to solve]

However, in the method of attaching the kneading ball cover as described above, the kneading ball cover is sandwiched between the mounting recess provided in the top plate of the housing and the holding plate through the screw engagement of the fixing screw. Therefore, when replacing the kneading ball cover, the housing must be disassembled into upper and lower halves, and the open end of the kneading ball cover must be sandwiched between the mounting recess and the holding plate, and the fixing screw must be screwed in from the inside of the housing. However, there is a problem in that the replacement work is extremely troublesome.

The present invention is an attempt to improve the above-mentioned problems and eliminates the troublesome work of sandwiching the open end of the kneading ball cover between the mounting recess and the holding plate, and the disassembled housing. There is a problem to be solved in that the kneading ball cover can be easily replaced without requiring the troublesome work of screwing together a fixing screw from the inside. That is, in the present invention, a flange is provided on the housing side of the massaging machine, and the massaging ball cover is secured to the flange through the fastening of strings, and the panel is detachably attached to the housing so that the fastened portion can be covered. The device is characterized in that the above-mentioned problems are solved by attaching the device to the device, and the specific means thereof are as follows.

[Means for solving problems]
