Specifically, for example, a roller-type massage device is placed on a floor or the like, and a user seated in a chair places feet on the massage device, thereby imparting a vibratory massage to the soles of the feet or the like. In addition, when the roller type massage device is placed on the leg of the user seated on the chair, vibration massage is applied to the leg.

However, the conventional roller type massage device is a device that generates vibration by rotating a weight portion (eccentric body) attached to a rotating shaft of a driving motor. Therefore, when such a roller-type massage apparatus is used by being placed on a floor or the like, for example, the entire apparatus vibrates greatly when the power is turned on, and the vibration is transmitted to the floor or the like, and there is a risk that the apparatus moves in an unexpected direction before the feet are placed on the main body. That is, the timing at which the power is turned on is difficult to grasp, and the massage cannot be performed at a predetermined position, and thus the use of the roller-type massage apparatus becomes difficult.

In addition, when the user places the roller type massage apparatus on the legs and uses the apparatus, the user pushes the end portion with a hand, and thus the hand may be numbed or itchy due to vibration, and thus a good massage effect may not be obtained.

Detailed Description

Hereinafter, an embodiment of the massage device 1 according to the present invention will be described with reference to the drawings.

The embodiment described below is an example of embodying the present invention, and the configuration of the present invention is not limited to the specific example. In the drawings, parts of the components are omitted for easy viewing, and the components are drawn using imaginary lines or the like. In addition, regarding the orientation of the massage device 1, for example, the left side of the paper in fig. 1 is referred to as "one side" of the massage device 1, and the right side of the paper is referred to as "the other side" of the massage device 1. The same applies to the directions of the massage device 1 shown in fig. 2 to 8.

As shown in fig. 1 to 8, the massage apparatus 1 according to the present invention is an apparatus for applying a massage by vibration to a treatment site such as a foot T, a leg, or a waist.

For example, the massage device 1 of the present invention is placed on a floor F or the like, and a user seated in a chair places feet T on the massage device 1, thereby giving a vibration massage to the sole of the foot or the like by the massage device 1 (see fig. 8).

Further, although not shown, the massage device 1 of the present invention is configured such that the massage device 1 is placed on the legs of a user seated in a chair and supported by hands, whereby the massage device 1 can apply vibration massage to the legs. In addition, the massage device 1 can apply vibration massage to the waist portion by the user sitting on the chair in a state where the massage device 1 is sandwiched between the waist portion and the backrest portion.

The massage device 1 according to the present invention will be specifically explained.

The massage device 1 of the present invention is characterized by comprising: a "vibration part" having a roller shape for applying a massage by vibration to a treatment site; and "non-vibration portions" which are provided on both sides of the vibration portion and are not transmitted with vibration.

The massage device 1 of the present invention includes: a vibration generating mechanism 2 for applying a massage based on vibration to the treatment site; a base body 3 that houses the vibration generating mechanism 2; a cylindrical intermediate cylinder 4 that surrounds the base body 3 in the circumferential direction and is vibrated by the vibration generating mechanism 2; a cylindrical cover body 5, wherein a middle cylinder body 4 is embedded outside the cover body, and a treatment piece 6 is arranged on the surface of the cover body; and a grip portion 7 provided at a longitudinal end of the cover 5. That is, the massage device 1 of the present invention is a roller type vibration massage device.

The massage device 1 of the present embodiment is provided with a middle cylinder 4. The middle cylinder 4 is also a member constituting the cover 5. That is, the cover 5 of the present embodiment is a combination of the cover 5 and the hollow cylindrical body 4 (double-layer structure). However, for example, only the cover 5 may have a single-layer structure.

As shown in fig. 3 and 4, the vibration generating mechanism 2 includes: a drive motor 8 generating a rotational drive force, a conversion member 9 converting the rotational drive force into an oscillating motion, and an oscillating piece 10 provided to the conversion member 9.

The drive motor 8 has a first output shaft 12a projecting from the main body 11 to one side and a second output shaft 12b projecting from the main body 11 to the other side. That is, the drive motor 8 is a biaxial (2-axis) drive motor. The drive motor 8 of the present embodiment outputs a rotational drive force to each of one side and the other side via one side output shaft 12a and the other side output shaft 12b.

In the present embodiment, the one-side output shaft 12a side is defined as the one-side vibration generating unit 2a, and the other-side output shaft 12b side is defined as the other-side vibration generating unit 2b. The one-side vibration generating portion 2a and the other-side vibration generating portion 2b are arranged symmetrically in the longitudinal direction (direction along the axial direction of the one side and the other side). That is, the one-side vibration generating part 2a may be said to be a member in which the other-side vibration generating part 2b is reversed in the longitudinal direction (mirror-reversed) and arranged at a predetermined interval. The one-side vibration generating portion 2a and the other-side vibration generating portion 2b are disposed adjacent to each other with the drive motor 8 interposed therebetween.

First, the one-side vibration generating section 2a will be described in detail

A projecting member 13a is mounted to the front end of the one output shaft 12a. The projecting member 13a is a member formed in a substantially cylindrical shape. The projecting member 13a of the present embodiment has a semi-cylindrical shape.

As shown in fig. 5, the projecting member 13a has: a cylindrical portion 14a having an axial center facing one side, a plate member 14c provided so as to protrude from the cylindrical portion 14a, and a weight portion 14b attached to the plate member 14 c.

The protruding member 13a is provided with a hole 14d into which the one output shaft 12a is fitted, on the horizontally opposite side of the cylindrical portion 14 a. The protruding member 13a is eccentrically rotated (vibration is generated) based on the eccentricity of the center axis of the cylindrical portion 14 a.

The cylindrical portion 14a is provided to protrude from a wall surface of one side of the plate member 14 c. The cylindrical portion 14a is disposed such that the axial center L2 is oriented in the same direction as the axial center L1 of the one output shaft 12a but not in the same axial center. That is, the cylindrical portion 14a is eccentrically rotated based on the rotation of the one output shaft 12a. The cylindrical portion 14a rotates eccentrically with respect to the one output shaft 12a, and the rotational motion is converted into the vibrational motion by the conversion member 9a.

The weight portion 14b is provided at a position (opposite position) opposed to the axial center of the one output shaft 12a and the axial center of the eccentrically rotating cylindrical portion 14a with respect to the weight, shape, and the like thereof being able to be appropriately changed. That is, the weight portion 14b is provided at a position of 180 ° with respect to the axial center of the cylindrical portion 14 a.

The axial center of the one cylindrical portion 14a and the axial center of the other cylindrical portion (not shown) of the protruding member 13b are the same. That is, the cylindrical portion 14a on the one side and the cylindrical portion of the projecting member 13b on the other side do not rotate differently from each other, for example, rotate 90 ° behind, rotate in the opposite direction, or the like. That is, the eccentric directions of the projecting member 13a on the one side and the projecting member 13b on the other side are the same.

The weight portion 14b on the one side and the weight portion (not shown) of the projecting member 13b on the other side are disposed in the same direction. For example, if the weight portion 14b on one side is located on the upper side, the weight portion of the projecting member 13b on the other side is also located on the upper side.

Next, the operation of the cylindrical portion 14a and the weight portion 14b will be described.

The cylindrical portion 14a is eccentrically rotated by the rotational driving force output from the one output shaft 12a. The cylindrical portion 14a eccentrically rotates to transmit a rotational motion to the one switching member 9a. The conversion member 9a converts the rotational motion into the vibrational motion. At this time, the vibration motion converted by the conversion member 9a is transmitted to the main body 11 side of the drive motor 8.

However, if the weight portion 14b is not provided on the eccentrically rotating cylindrical portion 14a side, the vibration to the main body portion 11 side is transmitted without being cancelled, and the entire massage device 1 vibrates greatly. If this occurs, the massage device 1 may roll in an unexpected direction.

In order to prevent the above phenomenon, in the present embodiment, the weight portion 14b is provided on the cylindrical portion 14a side. The weight portion 14b rotates around the axis of the cylindrical portion 14a by the eccentric rotation of the cylindrical portion 14 a. The rotation of the weight portion 14b eliminates vibration toward the main body portion 11, thereby suppressing transmission of vibration.

Since the conversion member 9a converts the vibration into the vibration and the transmission of the vibration of the drive motor 8 to the main body 11 can be suppressed by providing the projecting member 13a according to the present embodiment, the grip portion 7a is hardly transmitted with the vibration motion converted by the conversion member 9a and becomes a non-vibration portion, and the vibration portion is defined only as the cover 5 including the treatment member 6. By providing the massage apparatus 1 with this configuration, the user can easily hold the massage apparatus 1 by gripping the grip portion 7.

The conversion member 9a is attached to one side tip (cylindrical portion 14) of the protruding member 13a. The conversion member 9a of the present embodiment is a member formed in a cross shape. Specifically, the switching member 9a is a member formed with 4 protruding pieces 15a facing in directions intersecting each other.

The space formed between the respective projecting pieces 15a is a space through which a coupling member 39 (described below in detail) for coupling the base body 3a and the holding portion 31 (described below in detail) on one side passes. A hole 16a is provided at a middle portion of the projecting piece 15a in the projecting direction.

As shown in fig. 5, a regulating shaft portion 21 (described in detail later) provided in the base body 3a is fitted into the hole portion 16a. In the present embodiment, the hole portion 16a is provided in 2 opposed protruding pieces 15a out of the 4 protruding pieces 15 a. The rotation of the conversion member 9a is restricted by fitting the restricting shaft portion 21 of the base body 3a into the hole 16a. That is, the hole 16a and the restricting shaft 21 can be said to be "rotation restricting portions" that restrict the rotation of the conversion member 9a within a predetermined range.

The vibrating piece 10a is provided at the tip of the protruding piece 15 a. In the present embodiment, the oscillator 10a is a rectangular projecting piece in a plan view. The vibrator 10a is fitted into a rectangular fitting hole 25a formed in the middle cylinder 4 (details will be described later).

Further, a hole 17 having the same axial direction as the cylindrical portion 14 is formed in the center of the conversion member 9a. A bearing 18 is fitted into the hole 17. The conversion member 9a is rotatably attached to the cylindrical portion 14 (the projecting member 13 a) via a bearing 18.

The thickness of the conversion member 9a (the depth of the hole 17) is set to be substantially the same as the height of the cylindrical portion 14. The height of the switching member 9a (the distance from the tip of the projecting piece 15a to the tip of the projecting piece 15a disposed at the opposing position) is substantially the same as the inner diameter of the intermediate cylindrical body 4. In the present embodiment, the height of the conversion member 9a is about 75 mm.

The conversion member 9a is attached to the base body 3a via an elastic member 19. Specifically, the elastic member 19 is a substantially cylindrical member, and is attached so as to fit the regulating shaft portion 21 of the base body 3a. The elastic member 19 may be formed of a flexible material (for example, a rubber sleeve (ブッシュ) member). The elastic member 19 absorbs the rotation of the conversion member 9a, thereby suppressing the transmission of vibration to other members and preventing the massage device 1 from being damaged.

The conversion member 9a rotates by being transmitted with a rotational driving force from the drive motor 8 via the projecting member 13a, but is converted into vibration by being fitted into the hole 16a to restrict the rotation within a predetermined range by the restricting shaft 21 of the base body 3a. The vibrating element 10a provided in the conversion member 9a is fitted into the fitting hole 25a, and the conversion member 9a vibrates the intermediate cylinder 4.

As described above, the other-side vibration generating portion 2b of the present embodiment is arranged by inverting (mirror-inverting) the one-side vibration generating portion 2a. That is, since the other-side vibration generating unit 2b and the one-side vibration generating unit 2a have substantially the same shape, only the outline of the configuration will be described.

A projecting member 13b is attached to the front end of the other side output shaft 12b. A cylindrical portion, not shown, into which the other output shaft 12b is fitted is provided to protrude from the boss member 13a. The protruding member 13b may be eccentrically rotated.

A conversion member 9b is attached to the tip of the projecting member 13b. The conversion member 9b of the present embodiment is a member formed in a cross shape. That is, 4 protruding pieces 15b are formed in the switching member 9b so as to extend in the direction intersecting each other.

A hole 16b into which a regulating shaft 23 (described later in detail) provided in the base body 3b is fitted is provided at a midway portion in the projecting direction of the projecting piece 15b. The hole 16b and the hole 16a of the conversion member 9a are similarly provided in 2 numbers. The rotation of the conversion member 9b is restricted by fitting the restricting shaft 23 of the base body 3b into the hole 16b. That is, the hole 16b and the restricting shaft 23 can be said to be "rotation restricting portions" that restrict the rotation of the conversion member 9b within a predetermined range.

The vibrating element 10b is provided at the tip of the protruding piece 15b. In the present embodiment, the vibrator 10b has the same shape as the vibrator 10a. The vibrator 10b is fitted into a rectangular fitting hole 25b formed in the middle cylinder 4.

A hole (not shown) is formed in the center of the conversion member 9b, and a bearing is fitted therein. The conversion member 9b is rotatably attached to the projecting member 13b via a bearing (not shown).

That is, the converting member 9b has the same shape as the converting member 9a. The conversion member 9b is attached to the base body 3b via an elastic member 19. Specifically, the elastic member 19 is attached so as to fit the regulating shaft portion 23 of the base body 3b. The elastic member 19 absorbs the rotation of the conversion member 9b to suppress the transmission of vibration to other members, thereby preventing damage to the massage device 1.

The conversion member 9b rotates by being transmitted with a rotational driving force from the driving motor 8 through the projecting member 13b, but is converted into vibration by being fitted into the restricting shaft portion 23 of the base body 3b in the hole portion 16b to restrict the rotation within a predetermined range. The vibrating element 10b provided in the conversion member 9b is fitted into the fitting hole 25b, and the conversion member 9b vibrates the intermediate cylinder 4.

As shown in fig. 4, the base body 3 is mounted to the main body portion 11 of the drive motor 8. In detail, the base body 3a is attached to one side wall surface of the main body 11. The base body 3b is attached to the other side wall surface of the main body 11.

First, the base body 3a will be described in detail.

The base body 3a is a disk-shaped member having a predetermined thickness. The outer diameter of the base body 3a is substantially the same as the outer diameter of the main body 11 of the drive motor 8. A hole 20 facing the same direction as the axial direction of the disk shape is formed in the center of the base body 3a. The hole 20 of the base body 3a is a through hole, and the one output shaft 12a is provided to penetrate therethrough.

The regulating shaft portion 21 is provided on the outer peripheral wall surface of the base body 3a. The restricting shaft portions 21 are provided in 2 pieces toward one side so as to correspond to the hole portions 16a of the conversion member 9a. That is, the pair of regulating shaft portions 21 is provided at facing positions across the one output shaft 12a. An elastic member 19 is attached to the restricting shaft portion 21.

Further, an engaging piece 22 is provided on the outer peripheral wall surface of the base body 3a. The engaging piece 22 is a plate extending to one side. The engaging piece 22 is formed to have a length in the longitudinal direction longer than the thickness of the base body 3a. That is, the engaging piece 22 is provided in a state of protruding from the base body 3a.

In the present embodiment, 4 engaging pieces 22 are provided at equal intervals on the outer peripheral wall surface of the base body 3a. The engaging piece 22 is a member that engages with a connecting member 39 (described later in detail) provided so as to pass through a space formed between the projecting pieces 15a of the switching member 9a.

Since the base body 3b is a member having substantially the same shape as the base body 3a, only the outline of the configuration will be described.

A hole, not shown, through which the other-side output shaft 12b passes is formed in the center of the base body 3b. The regulating shaft portion 23 is provided on the outer peripheral wall surface of the base body 3b. The restricting shaft portions 23 are provided at positions facing each other across the one output shaft 12b so as to correspond to the hole portions 16b of the converting member 9b. An elastic member 19 is attached to the regulating shaft portion 23.

Further, an engaging piece 24 is provided on the outer peripheral wall surface of the base body 3b. The engaging piece 24 is a plate extending to one side. In the present embodiment, 4 engaging pieces 24 are provided at equal intervals on the outer peripheral wall surface of the base body 3b. That is, the engaging piece 24 is a member that engages the connecting member 39 provided through a space formed between the projecting pieces 15b of the switching member 9b.

As shown in fig. 2, the middle cylinder 4 is a cylindrical member having a long length in the longitudinal direction. The middle cylinder 4 has a large space therein to house the vibration generating mechanism 2. The outer peripheral wall surface of the intermediate cylinder 4 is provided with a plurality of fitting hole portions 25. Specifically, 4 fitting hole portions 25a are provided in the outer peripheral wall surface of the middle cylinder 4.

The insertion hole 25a is formed in a rectangular shape in a plan view. The vibrating element 10a of the conversion member 9a is fitted into the fitting hole portion 25a. That is, the size of the insertion hole 25a is substantially the same as the size of the vibrator 10a.

Further, 4 fitting hole portions 25b are provided in the other outer circumferential wall surface of the intermediate cylindrical body 4. The insertion hole 25b is formed in a rectangular shape in a plan view. The vibrating element 10b of the conversion member 9b is fitted into the fitting hole 25b. That is, the size of the insertion hole 25b is substantially the same as the size of the vibrator 10b.

The middle cylinder 4 is connected to the conversion member 9 via the vibrator 10 fitted into the fitting hole 25. When the vibrator 10 vibrates by the conversion of the conversion member 9, the intermediate cylinder 4 vibrates. Further, in this embodiment, the length of the middle cylinder 4 = about 300 mm, the outer diameter = about 80 mm, and the inner diameter = about 75 mm.

As shown in fig. 1, the cover 5 is a cylindrical member having a length in the longitudinal direction substantially equal to the length of the intermediate cylindrical body 4. The cover 5 has a large space inside, and fits the cylindrical body 4. A plurality of treatment tools 6 are provided on the outer peripheral wall surface of the cover 5.

Specifically, the treatment members 6 are provided so as to bulge radially outward. The treatment members 6 are provided in plurality at regular intervals along the longitudinal direction of the cover 5. The shape (height, width, etc.) of the treatment member 6 can be appropriately changed according to the purpose of treatment.

As shown in fig. 6, in the present embodiment, the cover 5 has a double-layer structure of the outer cylindrical body 5a and the inner cylindrical body 5b. The outer cylinder 5a may be formed of a soft material (rubber, etc.), for example. The outer cylinder 5a is provided so as not to cause an unexpected pain or the like when the user presses the treatment site. The inner cylinder 5b is a member to which the middle cylinder 4 is externally fitted. Further, the inner cylindrical body 5b may be formed of a hard material, for example.

The cover 5 (the outer cylinder 5a and the inner cylinder 5 b) is in close contact with the intermediate cylinder 4. Thus, when the middle cylinder 4 vibrates due to the vibration of the vibrator 10, the cover 5 vibrates along with the vibration. It follows that the middle cylinder 4 and the cover 5 serve as "vibration parts".

In the present embodiment, the length of the cover 5 = about 300 mm (which is substantially the same as the length of the middle cylinder 4), the outer diameter = about 100 mm (which includes the height of the treatment device 6), and the inner diameter = about 80 mm (which is substantially the same as the outer diameter of the middle cylinder 4).

A grip 7 is provided at an end of the cover 5. Specifically, a grip portion 7a is provided on one end side of the cover 5. A grip portion 7b is provided on the other end side of the cover 5.

The grip portions 7a and 7b are mirror-inverted in the longitudinal direction and are arranged at predetermined intervals (symmetrically arranged). The grip portion 7a and the grip portion 7b are arranged adjacent to each other with the cover 5 interposed therebetween. The description will be given focusing on the grip portion 7a.

As shown in fig. 5, the grip portion 7a is a member formed in a disc shape. The grip portion 7a has an outer diameter larger than the outer diameter of the cover 5. An annular fitting portion 26 penetrating in the axial direction of the disk shape is formed at the center of the grip portion 7a. The annular fitting portion 26 is fitted over a projection 32a constituting the holding portion 31a (details will be described later).

In the present embodiment, a recess 27 is formed on the outer peripheral side of the grip portion 7a. The recess 27 is recessed inward in the radial direction of the grip portion 7a. That is, the outer peripheral side of the grip portion 7a is a member in which the convex portions 28 and the concave portions 27 (peaks and valleys) are alternately continuous. The grip portion 7a is a star-shaped disk member in a plan view. In the present embodiment, the top of the projection 28 has a shape of a substantially flat surface (not sharp) although curved.

The convex portion 28 is provided with a plurality of edge portions. Of the edge portions, a linear edge portion 29 facing the longitudinal direction (one side) serves as a placement portion 30 that can be placed on the floor F. Specifically, the placing portion 30 is formed by a pair of combinations of an edge portion 29a of the convex portion 28 and an edge portion 29b provided at a position facing each other with the concave portion 27 interposed therebetween. The linear edge portions 29a and 29b are brought into contact with the floor F, thereby forming a placement portion 30 on which the grip portion 7 can be placed on the floor F.

That is, it can be said that the placement portion 30 capable of being placed on the floor F is provided on the outer periphery of the grip portion 7. The placing unit 30 is configured to prevent the massage device 1 from rotating when the massage device 1 is placed on the floor F. That is, the placing unit 30 can be said to be a portion provided with the "rotation preventing unit".

In the present embodiment, the placement portion 30 is formed as the edge portions 29a and 29b of the convex portion 28, but a plane (for example, a polygonal slope such as a pentagon) obtained by cutting a part of the outer periphery of the grip portion 7 may be formed as the placement portion 30 that can be placed on the floor F. The grip portion 7 is held by the holding portion 31 in a loosely fitted state.

As shown in fig. 5 to 7, the holding portion 31 includes: a cylindrical projecting member 32 externally fitted to the annular fitting portion 26 of the grip portion 7; a cylindrical holding member 33 that holds the projecting member 32 in a loosely fitted state; and a ring member 34 that is fastened to the holding member 33 and prevents the projecting member 32 from coming off.

A holding portion 31a is provided on the grip portion 7a side. Further, a grip portion 7b is provided on the grip portion 7b side. The holding portions 31a and 31b are mirror-inverted in the longitudinal direction and are arranged at predetermined intervals (symmetrically arranged). The holding portion 31a and the holding portion 31b are arranged adjacent to each other with the vibration generating mechanism 2 interposed therebetween. The description will focus on the holding portion 31a. The holding portion 31a is provided to vibrate more than one side the generating portion 2a is further outward in one direction.

The projecting member 32a is a cylindrical member and is fitted to the annular fitting portion 26 of the grip portion 7a. As for the projecting member 32a, one direction outer side is largely opened, and one direction inner side (the other direction) is provided with a bottom panel 35. That is, the protruding member 32a is a bottomed cylindrical member.

A hole 36 is formed in the center of the bottom plate 35 in the same direction as the axial direction of the cylindrical shape. The hole 36 is a through hole and is penetrated by the holding member 33a. That is, the bottom plate 35 is an annular plate member.

The hole 36 formed in the bottom plate 35 is a through hole having a step difference in inner diameter. Hole 36 has hole 36a, hole 36b, and hole 36c arranged in this order from one side to the other side, and the inner diameters of the holes are different.

First, the inner diameter Φ a of the hole portion 36a is slightly larger than the outer diameter Φ G of the annular rib 42 protruding toward the other side in the ring member 34a (see fig. 6 and 7).

The inner diameter Φ B of the hole portion 36B is slightly larger than the outer diameter Φ D of the cylindrical portion of the holding member 33a (see fig. 6 and 7).

The inner diameter Φ C of the hole portion 36C is slightly larger than the outer diameter Φ E of a rib member 37 formed in a holding member 33a (see fig. 6 and 7).

The holding member 33a is a member formed in a cylindrical shape. The outer diameter of the holding part 33a is smaller than the inner diameter of the projection part 32 a. Specifically, the outer diameter Φ D of the cylindrical portion of the holding member 33a is smaller than the inner diameter of the hole portion 36B Φ B formed in the bottom panel 35 of the projecting member 32a (see fig. 6 and 7).

A rib member 37 is provided on the outer peripheral wall surface of the holding member 33a. The rib member 37 is formed in a shape (ring shape) protruding radially outward and curved in the circumferential direction. That is, the rib member 37 is provided so as to surround the outer periphery of the holding member 33a.

In the present embodiment, the rib members 37 are provided at 4 equal intervals on the outer peripheral wall surface of the holding member 33a. The rib 37 may be formed in a ring shape so as to surround the outer periphery of the holding member 33a.

The outer diameter Φ E of the rib member 37 is smaller than the inner diameter Φ C of the hole portion 36C formed in the bottom panel 35 (the boss member 32 a) (see fig. 6 and 7). Thus, the holding member 33a can support the projecting member 32a in a freely rotatable manner in a loosely fitted state.

Further, an engaging piece 38 is provided on the outer peripheral wall surface of the holding member 33a. The engagement piece 38 is provided on the other side of the rib 37. The engaging piece 38 is a plate piece that extends to protrude from the holding member 33a toward the other side.

In the present embodiment, 4 engaging pieces 38 are provided at equal intervals on the outer peripheral wall surface of the base body 3a. The engaging piece 38 is provided at a position facing the engaging piece 22 of the base body 3a. The engaging piece 38 is a member that engages with the connecting member 39 that passes through the space formed between the projecting pieces 15a of the conversion member 9a.

The coupling member 39 couples the holding member 33a and the base body 3a. The connecting member 39 is an elongated rod member having a long groove 40 formed in the longitudinal direction. The coupling member 39 is attached to the projecting engagement piece 22 (base body 3 a) by a fastening tool or the like while covering the groove portion 40. The coupling member 39 is attached to the projecting engagement piece 38 (holding member 33 a) at a position facing the engagement piece 22 by a fastening tool or the like while covering the groove 40.

That is, the coupling member 39 is provided so as to span between the holding member 33a and the base body 3a. Thereby, the holding member 33a and the base body 3a are reliably fixed by the coupling member 39.

Further, the cross-shaped conversion member 9a is provided between the holding member 33a and the base body 3a in a floating state. The projecting piece 15a of the switching member 9a is provided so as to project radially outward from the space between the adjacent coupling members 39. The projecting piece 15a swings in the spatial range between the adjacent coupling members 39.

The ring member 34a holds the projecting member 32a in a loosely fitted state by sandwiching the projecting member 32a together with the holding member 33a. The ring member 34a is inserted into the protruding member 32a and is attached to the holding member 33a by a fastening tool or the like.

The ring member 34 is a cylindrical member that is largely open on the one-direction outer side and is provided with a bottom plate 41 on the one-direction inner side (the other direction). That is, the ring member 34a is a bottomed cylindrical member. A through hole is formed in the center of the bottom plate 41.

The ring member 34a has an outer diameter smaller than an inner diameter of the projecting member 32a (see fig. 6 and 7).

A rib member 42 is provided on the other bottom surface of the bottom panel 41. The rib member 42 is formed in a shape (ring shape) protruding toward the other side and curved in the circumferential direction. That is, the rib members 42 are provided in a manner surrounding in the circumferential direction.

The inner diameter F of the rib member 42 is larger than the outer diameter Φ D of the cylindrical portion of the holding member 33a (see fig. 6 and 7). The rib member 42 is externally fitted with the holding member 33a. The ring member 34a and the holding member 33a are reliably fixed by a fastening tool or the like.

The outer diameter Φ G of the rib member 42 is smaller than the inner diameter Φ a of the hole portion 36a formed in the bottom panel 35 (the projecting member 32 a) (see fig. 6 and 7).

Thus, the ring member 34a is attached to the holding member 33a so as to sandwich the projecting member 32a toward the other side, and the projecting member 32a can be held in a loosely fitted state so as to be rotatable without rattling.

A cover member 43 is attached to one opening of the ring member 34 a. The cover member 43 is a disk-shaped member. The outer diameter of the cover member 43 is substantially the same as the outer diameter of the ring member 34 a. The cover member 43 is provided with an operation switch 44 such as a power switch for driving and stopping the massage apparatus 1 and a condition changing knob capable of changing the rhythm of vibration.

As described above, the holding portion 31b is provided on the grip portion 7b side. The holding portion 31b of the present embodiment is arranged by inverting (mirror-inverting) the holding portion 31a. That is, since the holding portion 31b has substantially the same shape as the holding portion 31a, only the outline of the configuration will be described.

The projecting member 32b is a cylindrical member and is fitted to the grip portion 7b. As for the projecting member 32b, one direction outer side is largely opened, and one direction inner side (the other direction) is provided with a bottom panel 45. That is, the protruding member 32b is a bottomed cylindrical member. The bottom plate 45 has a through hole 46 through which the holding member 33b passes.

The hole 46 formed in the protruding member 32b is a through hole having a step difference in inner diameter similar to the hole 36 of the protruding member 32 a. The inner diameters of the holes 46 formed in the projecting member 32b are substantially the same as the inner diameters of the holes 36a, 36b, and 36c of the projecting member 32 a.

The holding member 33b is a member formed in a cylindrical shape. The outer diameter of the holding member 33b is substantially the same as the outer diameter of the holding member 33a. That is, the outer diameter of the holding member 33b is smaller than the inner diameter of the hole portion 36 b.

A rib member 47 is provided on the outer peripheral wall surface of the holding member 33b. The rib member 47 has the same shape as the rib member 37 of the holding member 33a. That is, the rib member 47 is provided so as to surround the outer periphery of the holding member 33b.

The outer diameter of the rib member 47 is smaller than the inner diameter of the hole portion 46 (hole portion 36 c) formed in the projecting member 32 b. The holding member 33b can rotatably support the projecting member 32b in a loosely fitted state.

Further, an engagement piece 48 is provided on the outer peripheral wall surface of the holding member 33b. The engaging piece 48 has the same shape as the engaging piece 38 of the holding member 33a. The engaging piece 48 is a plate extending to protrude from the holding member 33b to one side.

In the present embodiment, 4 engaging pieces 48 are provided at equal intervals on the outer peripheral wall surface of the base body 3b. The engaging piece 48 is provided at a position facing the engaging piece 24 of the base body 3b. The engaging piece 48 is a member that engages the connecting member 39 that passes through the space formed between the projecting pieces 15b of the conversion member 9b.

The coupling member 39 is attached to the protruding engagement piece 24 (base body 3 b) by a fastening tool or the like while covering the groove 40. The coupling member 39 is attached to the protruding engagement piece 48 (holding member 33 b) at a position facing the engagement piece 24 by a fastening tool or the like while covering the groove 40.

That is, the coupling member 39 is provided so as to be bridged between the holding member 33b and the base body 3b. Thereby, the holding member 33a and the base body 3a are reliably fixed by the coupling member 39.

Further, the cross-shaped conversion member 9b is provided between the holding member 33b and the base body 3b in a floating state. The projecting piece 15b of the switching member 9b is provided so as to project radially outward, and swings in a spatial range between the adjacent coupling members 39.

The ring member 34b holds the projecting member 32b in a loosely fitted state by sandwiching the projecting member 32b together with the holding member 33b. The ring member 34b is inserted into the protruding member 32b and is attached to the holding member 33b by a fastening tool or the like.

The ring member 34b has the same shape as the ring member 34 a. That is, the outer diameter and the inner diameter of the ring member 34b are substantially the same as those of the ring member 34 a.

The ring member 34b is provided with a rib member. The rib members are of the same shape as the rib members 42 of the ring member 34 a. That is, the outer diameter and the inner diameter of the rib member are substantially the same as those of the rib member 42.

Thus, the ring member 34b is attached to the holding member 33b so as to sandwich the projecting member 32b toward the other side, and the projecting member 32b can be held in a loosely fitted state so as to be rotatable without rattling.

That is, the projecting member 32 is held in a loosely fitted state by the holding member 33 and the ring member 34. The holding member 33 has the following configuration: is mounted on the base body 3 so as to be held in a floating state in the middle cylinder 4 and is not transmitted with vibration transmitted from the vibration generating mechanism 2 to the middle cylinder 4. As can be seen, the grip portion 7 is rotatably provided in a non-coupled state with respect to the cover 5, and serves as a "non-vibration portion" to which the vibration from the vibration generating mechanism 2 is not transmitted.

According to the present invention, in the massage device 1 for applying a massage effect based on vibration to a treatment site, for example, the protruding member 13a is provided with the eccentrically rotating cylindrical portion 14a and the weight portion 14b provided at a position opposed to the cylindrical portion 14a with the output shaft 12a on one side therebetween, so that the cylindrical portion 14a transmits a rotational motion to the conversion member 9a, and the weight portion 14b prevents a transmission of a vibration motion converted by the conversion member 9a to the main body portion 11 of the drive motor 8, and therefore the grip portion 7 becomes a non-vibration portion (is not transmitted with vibration), and the vibration portion is limited to the cover body 5 (including the vibration generation mechanism 2 and the middle cylinder 4) provided with the treatment member 6. The grip portion 7 is held in a free state with respect to the vibration portion (the vibration generating mechanism 2, the middle cylinder 4, and the cover 5).

By providing the massage apparatus 1 with such a configuration, the user can easily hold the massage apparatus 1 by gripping the grip portion 7. Further, even when the massage device 1 is used with the grip portion 7 placed on the floor F or the like, the vibration can be massaged at a predetermined position without being transmitted to the floor or the like.

That is, even if the power is turned on and the entire massage device 1 vibrates, the vibration is not transmitted to the floor or the like, and does not move in an unintended direction until the feet are placed on the main body.

It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects.

In particular, matters not explicitly shown in the embodiments disclosed herein, such as operating conditions, sizes and weights of components, do not depart from the scope of general practice of those skilled in the art, and matters that can be easily assumed by those skilled in the art are adopted.

For example, the configuration of the non-vibrating portion, that is, the outer diameter and inner diameter of the projecting member 32, the holding member 33, and the ring member 34 constituting the holding portion 31, the shape and separation distance of the left and right grip portions 7, the configuration of the vibrating portion (the vibration generating mechanism 2, the middle cylinder 4, and the cover 5), and the like can be appropriately changed in consideration of the treatment range.

In the present embodiment, the cylindrical shape has been described as an example of the cylindrical body such as the cylindrical body 4 and the cover 5, but the cylindrical body may have an elliptical shape in radial cross section or may have a polygonal shape (hexagonal shape or the like).
