The first and second rolling bearings 40 and 50 comprise first and second inner rings 42 and 52 and first and second outer rings 44 and 54 and first and second rolling balls 46 and 56 The first inner ring 42 of the first rolling bearing 40 is urged by the screw 60 and the second inner ring 52 of the second rolling bearing 50 is urged against the pressing step 70, And the first and second outer rings 44 and 54 are pressed against the projection 32 of the massage roller 30 while being pressed by the screw 60 so as to be brought into contact with the massage roller 30 And is rotated.

The massage handle 10 is a cylindrical shape having a smooth curved surface, which is a part that the user grasps when performing massage.

A pair of rotary shafts 20 are formed at one end of the massage handle 10. The rotary shaft 20 serves as a shaft when the massage roller 30 is inserted and the massage roller 30 is rotated.

The pair of rotary shafts 20 are formed to extend left and right at a predetermined angle with respect to the center axis of the massage handle 10.

At one end of the rotary shaft 20, a screw coupling groove 22 to which a screw 60 is coupled is formed.

A pressing step 70 is formed between the massage handle 10 and the rotary shaft 20 so as to be in close contact with the second inner ring 52 of the second rolling bearing 50.

The massage roller 30 is in the form of a sphere or an ellipsoid, and is made of a pair and is in direct contact with the skin.

A shaft insertion hole 34 is formed at the center of the massage roller 30 and is rotatably fitted to the pair of rotation shafts 20 in the shaft insertion hole 34.

The projection 32 is protruded inward from the shaft insertion hole 34 of the massage roller 30. The projection 32 is screwed into the shaft 60 of the first and second rolling bearings 40, 1 and 2 outer rings 44 and 54, respectively.

The roller cap 80 may be coupled to one end of the massage roller 30 to improve cosmetic appearance or to prevent foreign matter from entering the shaft insertion hole 34.

The massage roller 30 may be made of metal or synthetic resin.

When the massage roller 30 is formed of a metal material, the massage roller 30 may be formed of a stainless steel material or a copper or aluminum material having a high thermal conductivity to enhance a cooling effect.

When the massage roller 30 is formed of a synthetic resin material, a thermoplastic resin, a thermosetting resin, or a mixture of a thermoplastic resin and a thermosetting resin may be used. The thermoplastic resin may be polyethylene (PE), polypropylene (PP), polystyrene ), Polyvinyl chloride (PVC), polyester (PET), polyamide (PA), polyvinyl alcohol (PVA), polycarbonate (PC) and cellulose It is preferable to select at least one of a phenol resin, a urethane resin, a melamine resin and an epoxy resin as the thermosetting resin, and the thermoplastic resin and the thermosetting resin are mixed with 70 to 90% by weight of the thermoplastic resin and 10 to 30% by weight of the thermosetting resin , Polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyester (PET) ), Polyvinyl alcohol (PVA), polycarbonate (PC), and cellulose may be mixed with any one of a phenol resin, a urethane resin, a melamine resin and an epoxy resin.

In addition, the massage roller 30 may be plated to absorb heat of the skin to lower the skin temperature.

The massage roller 30 may have a spherical shape having an outer diameter of 18 mm to 32 mm.

When the outer diameter of the massage roller 30 is less than 18 mm, the size of the massage roller 30 is too small to collect the skin during skin massage. When the massage roller 30 is more than 32 mm, The size of the skin is too large to collect the skin when the force is too strong, the problem is that the skin is picked up.

7, when the curved surface of the massage roller 30 is extended to the upper and lower portions of the massage roller 30, the massage roller 30 may be in the shape of an ellipsoid, The shortest first distance l1 from the center to the surface is formed from 9 mm to 12.5 mm and the longest second distance l2 is formed from 13 mm to 16 mm and the first distance l1 and the second distance l2 ) May be formed to be 0.5 mm to 7 mm.

As the first distance l1 and the second distance l2 of the massage roller 30 become closer to each other, the effect becomes similar to that of the spherical roller, and the first distance l1 and the second distance l2, the larger the contact area of the massage roller 30 with the skin becomes, and the massage effect is increased.

However, if the difference between the first distance l1 and the second distance l2 is more than 7 mm, there is a problem that the area of the skin contacting the massage roller 30 in the skin massage is too wide, .

The amount of skin collected depending on the angle? 1 between the pair of massage rollers 30 can be varied. That is, when the angle? 1 is less than 111 °, the angle between the massage rollers 30 is small, so that the skin may be picked up when the skin is massaged and the user may suffer pain. When the angle? The angle between the massage rollers 30 is too large, so that the skin is not well gathered when the skin is massaged, and the meridian effect may be reduced.

In addition, the convenience of use may vary depending on the angle [alpha] 2 at which the massage roller 30 is tilted with respect to the central axis of the massage handle 10. [ That is, when the angle? 2 is less than 20, the user's hand touches the skin at the time of skin massage. When the angle? 2 exceeds 50, only the end portion of the massage roller 30 is intensively contacted with the skin The massage effect is significantly reduced.

The first and second rolling bearings 40 and 50 are installed on both sides of the protrusion 32 of the massage roller 30 so that the massage roller 30 can be rotated smoothly and stably do.

The first and second rolling bearings (40, 50) are not rolling bearings but rolling bearings.

The first and second rolling bearings 40 and 50 are composed of first and second inner rings 42 and 52 and first and second outer rings 44 and 54 and first and second rolling balls 46 and 56 .

The first inner ring 42 of the first rolling bearing 40 is urged by the screw 60 and the second inner ring 52 of the second rolling bearing 50 is urged against the pressing step 70, The first and second outer rings 44 and 54 are pressed against the projections 32 of the massage roller 30 while being pressed by the screw 60 and rotated together with the massage roller 30 .

The first and second outer rings 44 and 54 of the first and second rolling bearings 40 and 50 come into close contact with the inner periphery of the massage roller 30 and are rotated together with the massage roller 30.

A bearing is a mechanical element that fixes the axis of a rotating machine at a fixed position and rotates the shaft while supporting the self weight of the shaft and the load applied to the shaft. The bearing is also called a bearing, There are two types of sliding bearings: rolling bearing and rolling bearing.

The slide bearing has a shape in which the surface of the shaft is surrounded by a plane shape. A lubricant is provided between the contact surfaces to reduce friction. Since the slide bearing is in contact with the surface of the slide bearing, friction resistance Greater than rolling bearings.

On the other hand, the rolling bearing has a friction resistance smaller than a sliding bearing by inserting a ball, a roller, a needle or the like between the contact surfaces of the bearing, thereby reducing friction and power loss.

That is, the conventional ball massager has a structure in which the step 3a of the massage ball 3 is simply inserted into the groove 2b of the bearing member 2 as shown in Fig. 1, Friction between the outer periphery of the sliding bearing and the outer periphery of the bearing member 2 and the inner periphery of the sliding bearing occurs when the sliding bearing is provided between the massage ball 3 and the member 2, 3) is not easily rotated.

In addition, even if a rolling bearing is installed between the massage ball 3 and the bearing member 2, there is a problem that the rolling bearing function of the massage ball can not be utilized properly.

However, the present invention is not limited to the sliding bearing between the massage roller 30 and the rotary shaft 30 in the structure of the massage roller 30 and the rotary shaft 30 of the roller massage machine, The first and second rolling bearings 40 and 50 including the first and second inner rings 52 and 52 and the first and second outer rings 44 and 54 and the first and second rolling balls 46 and 56, 42 and 52 are fixed to the rotary shaft 20 and the first and second outer rings 44 and 54 are coupled to the massage roller 30. [

The massage roller 30 is rotated naturally while maintaining a certain angle with the rotary shaft 20 by reducing the friction between the periphery of the massage roller 30 and the outer periphery of the rotary shaft 20, The noise between the rotary shafts 20 can be reduced.

In other words, the improved roller massage device according to the present invention improves the arrangement and fastening method of the rolling bearings so that the first and second inner rings 42, 52 of the first and second rolling bearings 40, And the first and second outer rings 44 and 54 are individually rotated by the first and second rolling balls 46 and 56 so that the function of the rolling bearing can be utilized properly.

The screw (60) is screwed or forcedly coupled to an end of the rotary shaft (20).

The screw 60 is composed of a pressing portion 62 for pressing the first rolling bearing 40 and a coupling portion 64 for coupling to the rotary shaft 20.

The diameter t1 of the pressing portion 62 of the screw 60 is smaller than the inner diameter t2 of the first outer ring 44 of the first rolling bearing 40. The diameter t1 of the pressing portion 62 t1 is greater than the inner diameter t2 of the first outer ring 44, the pressing portion 62 strongly presses and fixes the first inner ring 42 as well as the first inner ring 42 to the first outer ring 44, (30) is not rotated.

A method of assembling a roller massage device with an improved coupling structure of the rollers will now be described with reference to the accompanying drawings.

In order to assemble the roller massage device with improved roller coupling structure according to the present invention, as shown in FIG. 7, the second rolling bearing 50 is inserted into the rotary shaft 20 formed at one end of the massage handle 10, So that the second inner ring 52 of the second rolling bearing 50 is brought into close contact with the pressing step 70.
