Specifically, this link 14 can swing with mutual connection angle (substantially vertical) changeless state with above-mentioned tilting member 13L, 13R, thus, even if bracing frame 7 swings, also link 14 can be maintained and the connection angle between tilting member 13L, 13R immobilizes.When adopting structure tilting member 13L, 13R connected to each other as described above by link 14, link 14 can be utilized reliably to support the moment (bending force) put on the pivotal support point of tilting member 13L, 13R.

That is, when making air bag 9 expand, produce and make tilting member 13 towards the moment (bending force) on the direction of movement outside width, and the moment (bending force) produced putting on the pivotal support point side of tilting member 13.In this situation, when the upper end side of tilting member is directly pivotally supported on back bracket parts 11, above-mentioned moment is directly passed to back bracket parts 11, and therefore the pivotal support structure of back bracket parts 11 self must be firmly.

But, tilting member 13L, 13R is connected utilizing link 14 as mentioned above, and when linkage unit 12 (link 14 being connected to the unit on back bracket parts 11 in the mode swung freely) is set on link 14, owing to being the moment instead of the back bracket parts 11 that are born generation when air bag 9 expands by link 14, therefore, without the need to reinforcing tilting member 13L, 13R pivotal support structure relative to back bracket parts 11.And then, the miniaturized structure of back-rest 4 can be made.In addition, can easily bracing frame 7 be installed in existing back-rest 4, and without the need to changing the structural design etc. of back-rest 4.

Then, the position switching mechanism for the first embodiment is described in detail.

The position switching mechanism of the first embodiment adopts ratchet (ratchet) mechanism, and ratchet mechanism 21 is configured in linkage unit 12.

As shown in Figure 4,5, linkage unit 12 is parts link 14 being connected in a rotatable manner back bracket parts 11 upper end, and is respectively equipped with one in the right-hand member side of link 14 and left end side, is provided with one group two altogether.Each linkage unit 12 possesses clamping part 18, protrusion tab 19, pivotal support axle 20 and ratchet mechanism 21 respectively, wherein, clamping part 18 is arranged on the upper end side of back bracket parts 11, the link 14 that protrusion tab 19 is arranged on above-mentioned bracing frame 7 is sandwiched in this clamping part 18, pivotal support axle 20 is for connecting clamping part 18 and protrusion tab 19, and with the mode pivotal support clamping part 18 rotated freely around the axle towards left and right directions and protrusion tab 19, ratchet mechanism 21 is for remaining predetermined angular by protrusion tab 19 relative to the rotational angle of clamping part 18.

Clamping part 18 is provided with pair of right and left erect plate, and this pair of right and left erect plate erects in mode outstanding upward the upper end side being arranged on back bracket parts 11.Protrusion tab 19 is installed to be the parts outstanding from the back side of link 14 towards rear, and arrange with the state between the erect plate inserting above-mentioned clamping part 18.Pivotal support axle 20 to install towards the mode of left and right directions, and with the rotatable rear end side of mode pivotal support protrusion tab 19 and the upper end side of clamping part 18.

In addition, ratchet mechanism (position switching mechanism) 21 possesses: be formed at the V shape notch 16 in the outer rim (lower edge) of protrusion tab 19, by engaging with the notch 16 of protrusion tab 19 thus limiting pawl component 17 that protrusion tab 19 rotates, applying towards engaging the force application part 22 of the power in direction and the releasing parts 23 engaged for removing protrusion tab 19 and pawl component 17 with notch 16 for this pawl component 17.

When utilizing this ratchet mechanism 21 that the rotational angle of protrusion tab 19 is remained predetermined angular, bracing frame 7 is swung toward the front relative to back bracket parts 11.So, the protrusion tab 19 of linkage unit 12 relative to clamping part 18 pivotally back shaft 20 rotate, be biased the pawl component 17 that parts 22 apply power to engage with the notch 16 of the protrusion tab 19 rotated, thus restriction protrusion tab 19 is towards counter-rotation, the position of sidepiece Massage Department 6 can be remained " using state " thus.On the other hand, when making this bracing frame 7 rotate toward the front further from " using state ", remove parts 23 to abut with pawl component 17, thus make pawl component 17 depart from notch 16, the location restore of sidepiece Massage Department 6 thus can be made for " housed state ".

Then, action, the in other words moving back and forth of sidepiece kneading device 2 for the position switching mechanism (ratchet mechanism) 21 of above-mentioned first embodiment are described.

When being made sidepiece Massage Department 6 move to " using state " from " housed state " by position switching mechanism, carry out following operation.

Namely, be in the chair-type massage machine 1 of " housed state " in sidepiece Massage Department 6, housing 5 is rocked to its left surface with back-rest 4 and the overlapping such pendulum angle of right flank, and the sidepiece Massage Department 6 being arranged at this housing 5 inside is also configured to contact with the two sides of back-rest 4.Therefore, the sidepiece kneading device 2 being in " housed state " cannot utilize sidepiece Massage Department 6 to harmonize the body the treatment position of sidepiece.

Therefore, first user catches the lower end side of the housing 5 of sidepiece kneading device 2 with hands, and the lower end side of housing 5 is swung towards the front of back-rest 4 centered by upper end side.So while housing 5 swings toward the front, the bracing frame 7 being configured in this housing 5 inside swings toward the front relative to the back bracket parts 11 being arranged on back-rest 4 inside.And, in linkage unit 12, be connected to protrusion tab 19 on bracing frame 7 relative to the clamping part 18 being arranged on back bracket parts 11 upper end side and pivotally back shaft 20 swings.

Then, after protrusion tab 19 reaches size to a certain degree relative to the rotational angle of clamping part 18, ratchet mechanism 21 carries out work, thus make the state of sidepiece kneading device 2 become sidepiece Massage Department 6 mobile toward the front after " using state ".Under this " using state ", the sidepiece Massage Department 6 pairs for the treatment of such as shoulder or the arm positions moving to front can be utilized to massage.

In addition, when making the housing 5 under this " using state " swing toward the front further around the axle towards left and right directions, removing parts 23 and abutting with pawl component 17, thus by the engagement releasing of pawl component 17 with notch 16.Therefore, it is possible to make pawl component 17 be separated with notch 16, protrusion tab 19 can be made thus towards counter-rotation, thus the state of sidepiece kneading device 2 can be made to revert to " housed state " from " using state ".

Thus, because the end side of left side tilting member 13L and the end side of right side tilting member 13R are connected by the strip link 14 towards the width of back-rest 4, this link 14 is to be pivotally supported on back-rest 4 around the mode freely of the axis rotation towards width (left and right directions), therefore, as long as make any one sidepiece Massage Department 6 of left and right move toward the front, thus the position of this sidepiece Massage Department 6 is switched to " using state " from " housed state ", just another sidepiece Massage Department 6 be connected via any one sidepiece Massage Department 6 of link 14 and this can be made also to move toward the front simultaneously, thus can the sidepiece Massage Department 6 of the left and right sides be switched to " using state " simultaneously.

About above-mentioned action form, action effect, be also identical when making sidepiece Massage Department 6 move to housed state.

In addition, existing sidepiece kneading device adopts following formation sometimes, that is: housing rotates around the axle towards above-below direction, and swing in the mode that inner side is rotated toward the front outside the left and right directions of back-rest, thus the advance and retreat state of sidepiece kneading device is become " using state " from " housed state ".

When adopting ratchet mechanism to keep the advance and retreat state of sidepiece kneading device in above-mentioned existing sidepiece kneading device, when the massage intensity of sidepiece kneading device is excessive and when making sidepiece kneading device revert to " housed state ", also need further toward the front inner side pressing housing just can revert to " housed state ", thus user can be made to feel under the weather for the moment.

The fixing hole for combining pair of right and left upper links parts is formed respectively in the upper end side of guiding groove 33 and lower end side.In the fixing hole being formed at guiding groove 33 lower end side, be embedded with the columnar component (bottom steady pin 36) outstanding facing to inner side of guiding groove 33 side be formed from the pair of right and left upper links parts be combined, this bottom steady pin 36 embeds in the elongated hole 39 be formed on lower link parts 37.

By engagement pin 38 is embedded in guiding groove 33, and bottom steady pin 36 is embedded in elongated hole 39, thus restriction upper links parts 32 significantly swing in the longitudinal direction.On the other hand, bottom steady pin 36 periphery is provided with spiral helicine spring 44.The end side of this spring 44 is by towards width bending, and the sweep 44a of this spring 44 abuts with the inner peripheral surface of elongated hole 39.The spring abutted with the inner peripheral surface of elongated hole 39 44 pairs of lower link parts 37 apply active force, thus promote lower link parts 37 toward the front.By utilizing the active force of this spring 44 to promote lower link parts 37 toward the front, thus engagement pin 38 is only slided facing one direction.That is, engagement pin 38 can not slide in the counterclockwise direction in the groove 33a on top.In addition, the engagement pin 38 engaged with following protuberance 35 applies the pressing force of the tiltedly below towards front side for protuberance 35, thus engagement pin 38 is reliably engaged with protuberance 35.

About guiding groove 33, the groove 33a on its top is formed wider for the groove 33b of bottom and above-below direction length is short, and the groove 33b of bottom is formed more elongated for the groove 33a on top (its width is a bit larger tham the diameter of engagement pin 38).In addition, the conversion portion of the groove 33a on top and the groove 33b of bottom is formed as level and smooth inclined-plane, thus the engagement pin 38 be formed on lower link parts 37 can move swimmingly.

The top end face of the groove 33a on top is formed with sagging shape protrusion tab, is provided with in the substantial middle position of the groove 33a on top and is formed towards the outstanding snap-latch piece 34 of left and right directions.

As shown in Fig. 8 ~ Figure 10, snap-latch piece 34 is rectangular shaped when side-looking, and its height is roughly the same with guiding groove 33 or slightly lower than guiding groove 33.In addition, the groove 33a on the space, the i.e. top that are surrounded by the inner peripheral surface of the neighboring of snap-latch piece 34 and the groove 33a on top has the width that engagement pin 38 can pass through.That is, the groove 33a on top guiding channel in the form of a ring when side-looking.

The upper side of the side of snap-latch piece 34 neighboring, i.e. an end margin (front side in Fig. 9) is formed with protuberance 35, and the engagement pin 38 after the upper side of other end edge (rear side Fig. 9) passes through engages with this protuberance 35.

Specifically, rise on the other end edge of snap-latch piece 34 by making to be positioned at the engagement pin 38 below snap-latch piece 34 and engage with protuberance 35, thus make sidepiece Massage Department 6L, 6R move to collecting position, in addition, by making engagement pin 38 cross protuberance 35, both engagings are removed, then make engagement pin 38 decline along an end margin and move to the below of snap-latch piece 34, thus make sidepiece Massage Department 6L, 6R move to use location.

At this, the situation when position switching mechanism 30 by the second embodiment being switched to use location and the collecting position of sidepiece Massage Department 6L, 6R carries out describing.

When upper links parts 32 are separated along its length with lower link parts 37, thus when making the engagement pin 38 of lower link parts 37 be positioned at the below of snap-latch piece 34 of upper links parts 32, sidepiece Massage Department 6L, 6R move to use location.In addition, when upper links parts 32 and lower link parts 37 are close along its length, thus when engagement pin 38 is engaged with the protuberance 35 of snap-latch piece 34, sidepiece Massage Department 6L, 6R move to collecting position.

Be provided with transfer strip 40 in the bottom of snap-latch piece 34, this transfer strip 40 for guide towards the groove 33b of bottom along an end margin of snap-latch piece 34 decline come engagement pin 38, namely switch to use location from collecting position.

Transfer strip 40 is L-shaped (hooking beautiful shape (comma-shapedbead-likeshape)) when being formed as side-looking, and to be arranged on immediately below snap-latch piece 34 around the mode freely of the axis rotation towards left and right directions.

All the time in the state rotated towards end side under the effect of the active force that this transfer strip 40 applies at spiral spring 45, now, the front end of one side of transfer strip 40 abuts with the conversion portion of guiding groove 33, and the upper side of its another side abuts with the bottom surface of snap-latch piece 34, thus by the end side shutoff of guiding channel, limit thus when the engagement pin 38 be positioned at below snap-latch piece 34 rises and move towards one end edge side of snap-latch piece 34.

Otherwise, when transfer strip 40 become the active force applied with spring 45 resist mutually and towards the state of the other end sideway swivel time, become breakthrough status by the end side of the guiding channel of shutoff, thus the engagement pin 38 of coming of the end margin along snap-latch piece 34 can being declined guides to the below of snap-latch piece 34.

That is, this transfer strip 40 can limit and be positioned at engagement pin 38 below snap-latch piece 34 and move towards one end edge side of snap-latch piece 34 when rising, and the engagement pin 38 of coming of the end margin along snap-latch piece 34 can being declined guides to the below of snap-latch piece 34.And after below engagement pin 38 being guided to snap-latch piece 34, transfer strip 40 rotates towards end side and returns to original position (position by the end side shutoff of guiding channel) under the effect of the active force of spring 45.That is, transfer strip 40 makes the groove 33a on top become clockwise guiding channel.

On the other hand, ejecting mechanism 41 is configured in and upper links parts 32 and lower link parts 37 (position switching mechanism 30) adjoining position place along the vertical direction, and it moves along the vertical direction for making upper links parts 32.The ejecting mechanism 41 of the second embodiment adopts cylinder, but, as long as the mechanism that such as hydraulic cylinder or Linear actuator etc. reciprocal along the vertical direction (stretching) move, be just not particularly limited.

The bottom of this ejecting mechanism 41 is to be pivotally supported on back bracket parts 11 around the mode freely of the axis rotation towards width, and its top is to be pivotally supported on protrusion tab 31 around the mode freely of the axis rotation towards width.Extended by ejecting mechanism 41 and promote upward upper links parts 32, thus link 14 is rearward rotated around the axle center towards width.So tilting member 13L, 13R become using state.

In addition, shunk by ejecting mechanism 41 and upper links parts 32 are moved downward, thus link 14 is forwards rotated around the axle center towards width.So tilting member 13L, 13R, in other words sidepiece Massage Department 6L, 6R become housed state.In addition, the contraction of ejecting mechanism 41 promotes the operation of sidepiece Massage Department 6L, 6R by user towards collecting position (lower side) and realizes.

Then, the action of the position switching mechanism 30 of above-mentioned second embodiment, the in other words moving back and forth of sidepiece Massage Department 6L, 6R are described.

Fig. 9 is the A-A profile of Fig. 6, and is the sectional side view of the state of position switching mechanism 30 and ejecting mechanism 41 (cylinder) when representing that sidepiece Massage Department 6L, 6R are engaged in use location.

Figure 10 is the B-B profile of Fig. 7, and is the sectional side view of the state of position switching mechanism 30 and ejecting mechanism 41 when representing that sidepiece Massage Department 6L, 6R are engaged in collecting position.

First, when being in use location with reference to Fig. 9 for sidepiece Massage Department 6L, 6R, the state of position switching mechanism 30 and ejecting mechanism 41 is described.

When sidepiece Massage Department 6L, 6R are in outstanding toward the front state (use location), position switching mechanism 30 extends along with ejecting mechanism 41 and extends along its length.That is, promote upward upper links parts 32 by the elongation of ejecting mechanism 41, thus make upper links parts 32 while slip away from lower link parts 37.Now, engagement pin 38 is positioned at guiding groove 33 and the below of snap-latch piece 34.

Any restriction is carried out in the action of not counter-lateral quadrents Massage Department 6L, the 6R of the position switching mechanism 30 in state shown in Fig. 9, but is abutted with the rear side of pivotal support sheet 42 by pivoting support member 43, thus limits link 14 and rotate towards rear further.That is, sidepiece Massage Department 6L, 6R (pair of right and left tilting member 13L, 13R) is stably fixed use location place.

Then, when user hands promotes sidepiece Massage Department 6L, 6R towards rear, sidepiece Massage Department 6L, 6R change the side that is positioned at back-rest 4 into and state (collecting position) downward from state (use location) outstanding toward the front.Now, make its action swung towards rear along with user hand propelled sidepiece Massage Department 6L, 6R and ejecting mechanism 41 is shunk.

And position switching mechanism 30 also shrinks along its length along with the contraction of ejecting mechanism 41.That is, by the contraction of ejecting mechanism 41, upper links parts 32 are moved downward, thus make upper links parts 32 while slip near lower link parts 37.

Meanwhile, link 14 forwards rotates around the axle center towards width.Rotated toward the front by this link 14, thus make sidepiece Massage Department 6L, 6R be rocked to state (collecting position) downward from state (use location) toward the front.

Now, engagement pin 38 as the thick arrow in Fig. 9 be shown in guiding groove 33 and slide.

That is, shunk by ejecting mechanism 41 and make the engagement pin 38 be arranged in below snap-latch piece 34 from the groove 33b of bottom, rise to the groove 33a on top via conversion portion (trailing flank of transfer strip 40).After in the groove 33a rising to top, engagement pin 38 is mobile along the other end edge (on rear side of posterior edges ~ upper end-face edge) of snap-latch piece 34.In addition, due in transfer strip 40 by the state of the end side shutoff of guiding channel, therefore, be positioned at engagement pin 38 below snap-latch piece 34 and can not move towards one end edge side of snap-latch piece 34 when rising.

Then, engagement pin 38 engages with the protuberance 35 on the upper end-face edge of snap-latch piece 34.Because the elongation by ejecting mechanism 41 applies the power that makes it decline for the engagement pin 38 engaged with protuberance 35 always, therefore, engagement pin 38 pairs of protuberances 35 apply pressing force.Make engagement pin 38 firmly be fastened on protuberance 35 by this pushing force, thus become state as shown in Figure 10.

That is, under the state of Figure 10, position switching mechanism 30 shrinks along its length along with the contraction of ejecting mechanism 41.That is, by the contraction of ejecting mechanism 41, upper links parts 32 are moved downward, thus make upper links parts 32 while slip near lower link parts 37.By the action of this position switching mechanism 30, link 14 is forwards rotated around the axle center towards width.

In addition, when being in collecting position, engagement pin 38 engages with the protuberance 35 of snap-latch piece 34, thus sidepiece Massage Department 6L, 6R (tilting member 13L, 13R of pair of right and left) are firmly fixed on collecting position place.

Then, when moving to use location from collecting position for sidepiece Massage Department 6L, 6R, the state of position switching mechanism 30 and ejecting mechanism 41 is described.

When user hands promotes towards rear to be in sidepiece Massage Department 6L, 6R of collecting position further, sidepiece Massage Department 6L, 6R change state (use location) toward the front into from state (collecting position) outstanding downward.Now, ejecting mechanism 41 temporarily shrinks when user hands promotes sidepiece Massage Department 6L, 6R further towards rear, then extends again.

Then, position switching mechanism 30 is temporarily shrinking its elongated lengthwise of tailing edge.That is, upper links parts 32 move upward after moving downward in the temporary transient contraction along with ejecting mechanism 41, thus away from lower link parts 37 while slip.Made link 14 rotate towards rear after rotating temporarily to front around the axle center towards width by the action of this position switching mechanism 30.

Therefore, rotated towards rear by link 14, thus make to be connected to pair of right and left tilting member 13L, 13R (sidepiece Massage Department 6L, 6R) on link 14 and be rocked to state (use location) toward the front from state (collecting position) downward.

Now, engagement pin 38 as the thick arrow in Figure 10 be shown in guiding groove 33 and slide.

Namely, promote sidepiece Massage Department 6L, 6R towards rear further by user hands, thus make the engagement pin 38 below snap-latch piece 34 from rising between protuberance 35 with the edge of sagging shape protrusion tab, namely engagement pin 38 cross protuberance 35 thus engagement pin 38 removed with the engaging of protuberance 35.Then, engagement pin 38 declines along an end margin (on front side of upper end-face edge ~ forward edge).Engagement pin 38 abuts with the leading flank of transfer strip 40 after decline.

Then, along with ejecting mechanism 41 extends, engagement pin 38 makes transfer strip 40 rotate towards another side (clockwise).By making transfer strip 40 towards other end sideway swivel, thus make to be become breakthrough status by the end side of the guiding channel of shutoff, engagement pin 38 passes through from the end side of this guiding channel and moves to the below of snap-latch piece 34.

After engagement pin 38 moves to below snap-latch piece 34, under the effect of the active force applied at spiral spring 45, transfer strip 40 is again by the end side shutoff of guiding channel.

Thus, by making sidepiece Massage Department 6L, 6R swing toward the front from below, thus the using state shown in Fig. 9 is changed into.

As mentioned above, by the position switching mechanism 30 of the second embodiment, in use sidepiece Massage Department 6L, 6R can be firmly positioned use location place, and not use Shi Shi sidepiece Massage Department 6L, 6R retreat the side to back-rest 4 swimmingly and are fixed its position.

[the 3rd embodiment]

Then, with reference to the accompanying drawings the 3rd embodiment of chair-type massage machine 1 of the present invention is described.

As shown in figure 11, the formation of chair-type massage machine 1 that relates to of the 3rd embodiment is roughly the same with the device (with reference to Fig. 6) of the second embodiment.

Namely, the chair-type massage machine 1 of the 3rd embodiment is identical with the device of the second embodiment in following, that is: the sidepiece kneading device 2 that there is a portion 3, be built-in with the back-rest 4 of back bracket parts 11, be built-in with left and right sides Massage Department 6L, 6R and bracing frame 7, and, sidepiece Massage Department 6L, 6R have tilting member 13L, 13R, and bracing frame 7 possesses the link 14 of pair of right and left tilting member 13L, 13R and this pair of right and left tilting member of connection 13L, 13R.

In addition, be also identical in following, that is: be configured with the position switching mechanism switching sidepiece Massage Department 6L, 6R position in the longitudinal direction and the ejecting mechanism 41 promoting tilting member 13L, 13R toward the front in sidepiece kneading device 2 inside.In addition, the ejecting mechanism 41 of the 3rd embodiment adopts cylinder, but, as long as the mechanism that such as Linear actuator or hydraulic cylinder etc. reciprocal along the vertical direction (stretching) move, be just not particularly limited.

And then, be also identical in following, that is: on the bottom surface of link 14, be provided with pair of right and left limiting part, be provided with pair of right and left pivotal support sheet 42 in the upper end-face edge portion of back bracket parts 11.

But formation and second embodiment of the position switching mechanism 50 in the 3rd embodiment are different.

The position switching mechanism 50 of the 3rd embodiment is set to from the side (bottom surface) of link 14 protrusion tab 51 outstanding towards the direction crossing with the center of rotation of link 14.

Protrusion tab 51, i.e. position switching mechanism 50 are set to give prominence to downward from the bottom surface of link 14, and are configured with one in the left surface side in the upper end-face edge portion of back bracket parts 11.This protrusion tab 51 is parts plate being bent to U-shaped and is formed, and the base part being configured to U-shaped is fixed on the bottom surface of link 14, and two sheets after bifurcated are towards fore-and-aft direction or above-below direction.

Each after bifurcated is formed respectively along the direction parallel with the center of rotation of link 14, namely along the hole that the center of rotation towards width is through.The hole formed for by the end side (pull rod shaft) of ejecting mechanism 41 to be pivotally supported on protrusion tab 51 around the mode freely of the axis rotation towards width.

In addition, the end side (lower end side) of ejecting mechanism 41 is to be connected on back bracket parts 11 around the mode freely of the axis rotation towards width.

At this, the situation when position switching mechanism 50 by the 3rd embodiment being switched to use location and the collecting position of sidepiece Massage Department 6L, 6R carries out describing.

Centre position on same straight line is roughly in for boundary line with protrusion tab 51 and ejecting mechanism 41, extended by ejecting mechanism 41 and make protrusion tab 51 and ejecting mechanism 41 become towards the state of curving, thus making sidepiece Massage Department 6L, 6R move to use location.In addition, extended by ejecting mechanism 41 and make protrusion tab 51 and ejecting mechanism 41 become towards the bending state of opposite side, thus making sidepiece Massage Department 6L, 6R move to collecting position.

Then, the action of the position switching mechanism 50 of above-mentioned 3rd embodiment, the in other words moving back and forth of sidepiece Massage Department 6L, 6R are described.

First, when being in use location with reference to Figure 11, Figure 12 for sidepiece Massage Department 6L, 6R, the state of position switching mechanism 50 and ejecting mechanism 41 is described.

When sidepiece Massage Department 6L, 6R are in state (use location) outstanding toward the front, position switching mechanism 50 is oblique inclined downward towards front side, and ejecting mechanism 41 tilts towards oblique upper, front side.That is, state bending towards front side centered by the hole making position switching mechanism 50 and ejecting mechanism 41 become on protrusion tab 51 along with the elongation of ejecting mechanism 41.By the action of this position switching mechanism 50, link 14 is rearward rotated around the axle center towards width.

Therefore, rotated towards rear by link 14, thus make to be connected to pair of right and left tilting member 13L, 13R on link 14 and be rocked to state (use location) toward the front from state (collecting position) downward.

In addition, when being in use location, pivoting support member 43 abuts with the rear side of pivotal support sheet 42, thus restriction link 14 rotates towards rear further.That is, sidepiece Massage Department 6L, 6R (pair of right and left tilting member 13L, 13R) is stably fixed use location place.

Then, when moving from use location to collecting position for sidepiece Massage Department 6L, 6R with reference to Figure 13, the state of position switching mechanism 50 and ejecting mechanism 41 is described.

When user hands promotes sidepiece Massage Department 6L, 6R towards rear, sidepiece Massage Department 6L, 6R change state (centre position) a little downward into from state (use location) outstanding toward the front.Now, ejecting mechanism 41 makes it swing towards rear along with user hand propelled sidepiece Massage Department 6L, 6R and shrinks.And, shrink along with ejecting mechanism 41 and pull downward position switching mechanism 50, thus making position switching mechanism 50 become roughly hang.

That is, position switching mechanism 50 (protrusion tab 51) and ejecting mechanism 41 are roughly on the same straight line in vertically direction.By the action of this position switching mechanism 50, link 14 is rotated a little toward the front around the axle center towards width.
