DESCRIPTION OF THE INVENTION: _ Technical Field to Which the Invention Is A The present invention relates to a massager, and more particularly to a massager that can switch a massage range when a massager performs a tapping massage with a hand. [Prior Art] In the conventional portable massager, there is a massager that uses a driving mechanism such as a solenoid and a motor to reciprocally drive the massage portion, and massages the massaged person by a massaging massage. Generally, it is a driving mechanism. To drive the structure of a massage part. In the general configuration, there is a single massage range and a massage feeling, and there is a problem that the massage effect is monotonous. To solve this problem, the following components are proposed: '1) A plurality of massage parts and individual massage units are provided. The configuration of the drive mechanism (the following [2], [4]); 2) The configuration of a plurality of massage parts, one drive mechanism, and a mechanism for transmitting the drive force to the plurality of massage parts (the following [1], [3], [5], [6]). [1] Changing the rotation direction of the output shaft of the rotary drive device, from the power transmission portion of the multi-system #, the one-way clutch transmits power only to the specific system according to the rotation direction, and a plurality of different types of massagers are required to be performed by one massager. The configuration of the massage (vibration/knock) (for example, refer to Patent Document 1). [2] A pair of movable jaws that perform "same operation" in parallel with the inside of the body head are provided, and the contact portion is connected to each movable portion to provide stimulation so as to straddle the left and right sides of the affected portion (for example, refer to the patent). Literature 2). [3] Two massage heads for reciprocating motion by one solenoid are provided, so that the massage range can be expanded without adding a solenoid (for example, refer to Japanese Patent No. 1279229). [4] The first massage head, the second massage head surrounding the massage head, and the two drive mechanisms that individually drive the same, so that the focus/soft massage can be performed without the need to exchange the massage head (for example, Refer to Patent Document 4). [5] A partial convex portion coupled to the drive shaft; and a wide-range convex portion that is supported by the elastic support portion provided on the drive shaft and slidable relative to the drive shaft, and is transmitted when the human body is lightly pressed In the case of the local use and the wide range of the convex portions, the vibration of the local convex portion is transmitted when the human body is heavily pressed (for example, see Patent Document 5). [6] In order to change the massage width of the long massage part, a pair of massage heads are arranged on both sides of the long massage part, and the long massage head is connected to the long massage head in the lower rotation position of the sub massage head for coherent driving, and at the upper rotation position It is connected to the casing and drives only the long massage head so that wide/intermittent tapping can be performed (for example, refer to Patent Document 6). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. 7-59832 (Patent Document 3). Japanese Patent Laid-Open Publication No. JP-A No. 2000-350765 (Patent Document No. JP-A No. 2000-350765) However, in the above proposal, the part 1) is equipped with a driving mechanism only in accordance with the number of massage parts. Although the massage part can be appropriately selected, the size of the massager is 1279229 and is heavy, and it is expensive. Question. ~ For the part 2), the drive mechanism is only one, although it can be solved, but in the configuration [1], in order to choose the one-way clutch according to the rotation direction of the motor, the structure is complicated, and the two of the massager are complex. On the side, the massager is held in the process of switching the massage part. In the composition [3], the massage part is often staggered or at the same time, so that it is almost impossible to improve the monotonous composition of the massage effect [5], in order to change the degree of compression on the human body, the stimulation of the range of φ, and the local stimulation. However, in the massage part of the local thorn, it is still connected to the human body, and the difference in massage effect and the structure in which the range is switched is complicated. In addition, in the configuration [6], the structure of the width of the friction part is reduced even in the long massage part.
' 按摩範圍的長度仍維持較長，因此按摩範圍I 確。 本發明正是著眼於上述問題點而完成者， 提供一種具備適合於手提式的尺寸小且量輕， φ 及按摩間隔明顯變化的構成的按摩器。 (解決問題之手段） 爲達成上述目的，本發明之按摩器，其特 部；以可改變從頭部突出的突出量的方式所設 副按摩頭；使主按摩頭實施按摩動作的驅動機 性地將副按摩頭自由繫拆於主按摩頭上的繋合 頭及副按摩頭並行設於頭部的長度方向上。 根據該構成，副按摩頭可選擇性地自由繫 決1)的課題， 動的按摩部而 數的按摩部設 中有必要交替 I動複數（2個） 性。另外，在 即可切換爲廣 激時，廣範圍 不明確，且用 爲一^切換長按 寬度的情況， 的變化並不明 其目的在於， 可使按摩範圍 徵爲具備：頭 的主按摩頭及 構；及可選擇 機構；主按摩 拆於主按摩頭 1279229 且並行設於頭部的長度方向上’因此’若在將副按摩頭繫合 於主按摩頭的狀態進行按摩動作時’則按摩範圍成爲主按摩 頭及副按摩頭的合成長度，若在未將副按摩頭繫合於主按摩 頭的狀態進行按摩動作時，則僅由主按摩頭進行按摩動作， 其按摩範圍較副按摩頭繫合於主按摩頭的情況短，可明確使 按摩範圍及按摩間隔變化。 副按摩頭具有較主按摩頭的按摩動作的可動範圍大的 可動範圍，該可動範圍內的從頭部突出的突出量成爲最大的 | 一端側，最好相當於主按摩頭的可動範圍內的從頭部突出的 突出量成爲最大的一端側。藉此，在未將副按摩頭繫合於主 按摩頭的狀態、亦即僅主按摩頭進行按摩動作時，副按摩頭 不接觸於使用者的被按摩部位，可更爲明確地使按摩範圍及 按摩間隔變化。 主按摩頭及副按摩頭係分別可個別旋轉自如地樞支於 頭部的一端側，且轉動中心最好與頭部的長度方向正交。藉 此，可簡略化各按摩頭的構成，實現適合於手提式的小尺寸 § 且輕型化。 繫合機構係由設於副按摩頭的繫合部、設於主按摩頭的 主按摩頭側的被繫合部及設於頭部的頭部側的被繫合部所 構成’最好在繫合部繫合於主按摩頭側的被繫合部時，主按 摩頭及副按摩頭一體進行按摩動作，而在繫合部繫合於頭部 側的被繫合部時，僅主按摩頭進行按摩動作。根據該構成， 在僅由主按摩頭進行按摩動作時，副按摩頭則與頭部繫合不 進行動作’因此可防止不舒服的振動或噪音等的產生。 -9- 1279229 a 又’繫合部最好以可自由切換與主按摩頭側及頭部側的 被繫合部的繫合狀態及繫合解除狀態的方式設於副按摩頭 上’且對與主按摩頭側及頭部側的被繫合部繫合的繫合方向 附加彈力。藉此，可容易實現副按摩頭與主按摩頭的繫脫， 且可實現確實的繫合狀態的移行。 又’最好具備繫合部未繫合於主按摩頭側及頭部側的被 繫合部的任一者時，維持繫合解除狀態用的解除維持機構。 根據該構成’朝被繫合部的繫合方向附加彈力的繫合部，在 從副按摩頭未繫合於主按摩頭及頭部的被繫合部的任一者 的狀態移向與其任一繫合的狀態時，不需要重新將繫合部設 爲繫合解除狀態的操作。 又’繫合部與頭部側的被繫合部的繫合，最好在副按摩 頭的可動範圍的另一端側進行。根據該構成，可容易且確實 地實現副按摩頭與頭部的繫合。 又’最好具備解除繫合部與主按摩頭及頭部側的被繫合 部的繫合狀態用^的解除機構。另外，解除機構最好係具備設 爲從頭部突出，可沿解除繫合部與主按摩頭側及頭部側的被 繫合邰的繫合時的移動的方向進行操作的操作部；及伴隨操 作部的移動，使繫合部沿解除方向移動的解除部。藉此，可 容易且確實地實現繫合部與被繫合部的繫合解除。 又，解除部最好形成爲依照伴隨副按摩頭的轉動的繫合 邰的轉動軌跡的圓弧形狀。藉此，在副按摩頭繫合於主按摩 頭的情況及繫合於頭部的情況，使得不會產生解除繫合部與 被繫合部的繫合時的操作部的移動量及操作所需要的力差。 -10- ,1279229 又，副按摩頭最好係朝從頭部突出的方向被附加彈力。 藉此，即使爲繫合部與主按摩頭及頭部的任一者均未繫合的 狀態，副按摩頭仍自動移行至繫合於主按摩頭的狀態，因此 可容易且確實實現按摩範圍及按摩間隔的切換。 (發明效果） 根據本發明，因爲可選擇進行主按摩頭及副按摩頭並行 設於頭部的長度方向的狀態下的按摩及僅依主按摩頭的按 摩，所以明確地使按摩範圍及按摩間隔變化。而且該構成可 φ 以適合於手提式的小尺寸且輕型化構造而實現。 【實施方式】 以下，參照實施形態說明本發明之按摩器。 4 第1圖爲本實施形態之按摩器的通常使用狀態下的外觀 立體圖，另外，第2圖爲第1圖的按摩器的前視圖，第3圖 爲摺疊頭部狀態的按摩器的外觀立體圖，第4圖爲第3圖的 按摩器的前視圖。但是，在第1圖與第2圖〜第4圖中，在 外觀形狀的細部具有若干的差異。 # 該按摩器1係由使用時用以手握的本體2、及藉由軸部 4可轉動地連結於該本體2的頭部3所構成。頭部3係可朝 向本體2側彎曲約8 5度的範圍，使用時如第1圖、第2圖 所示般翻起頭部3，不使用時（收藏時）如第3圖、第4圖所 示般將頭部3摺疊。在第1圖、第2圖的使用狀態及第3圖、 第4圖的摺疊狀態的任一狀態，均由軸部4鎖定於頭部3上， 鎖定或解除係通過強制性讓本體2與頭部3相互接近或離開 來實施。 -11- 1279229 在本體2上設有電源開關7、程式/手動切換開關8及程 式選擇/速度調節刻度盤9。電源開關7係進行電源的開/關 的切換與按摩動作（敲打動作）的強弱的切換者。程式/手動切 換開關8係用以切換預設程式動作及手動動作者。程式選擇 /速度調節刻度盤9係於程式動作時用以切換預設的8種類 的程式，而於手動動作時用以將速度在8檔中進行切換者。 另外’本體2內裝有搭載各種電子零件的電路基板（未圖示） 等。 頭部3係沿正交於軸部4的方向形成爲細長形狀，其具 有外殼L11、外殼R12及外殼U13，外殻Lll、R12及U13 係作爲外殻相互嵌合而由螺絲一體組裝。主按摩頭6 0及副 按摩頭8 0係以並設於該頭部3 (外殻）的長度方向的方式出 現，藉由該主按摩頭6 0及副按摩頭8 0的相對頭部3的出入 動作（敲打動作）而對於被按摩者的部位（例如，肩部）進行按 摩。 在由外殻L 1 1、R1 2及U 1 3構成的外殻內部，收容有第 5圖所示的按摩機構1 5。 按摩機構1 5係第6圖〜第8圖的分解立體圖所示的構 造，具有如圖所示形狀的內殼L21(第6圖）與內殼R2 2 (第7 圖）。該一對的內殼L2 1、R22係作爲內殼相互嵌合而由螺絲 一體組裝。在由該一對的內殼L21、R22構成的內殼內安裝 有各種零件，該內殼係配置於由外殼L 1 1、R 1 2及u 1 3構成 的外殼內。 在第6圖中，按摩機構1 5具有作爲驅動機構的螺線管 -12- 1279229 Γ # 組裝體4 Ο。螺線管組裝體4 Ο具有支持板4 1、配置於該支持 ‘ 板4 1內側的線軸·線圈等的零件42、及可移動地插穿於零 件42的中心的柱塞43。從零件42延長的導線50係連接於 本體2內部所設的電路基板上。在柱塞43的一端部（上端部） 安裝有吸收衝擊·消音用的緩衝橡膠44，在支持板4 1的下 端部安裝有吸收衝擊·消音用的緩衝橡膠4 5。 在柱塞43的另一端部（下端部），以夾住連接橡膠47的 態樣而由螺絲及螺母固定有一對的柱塞連接器4 6，同時，通 φ 過嵌合而將主按摩頭連接器48安裝於連接橡膠47上。主按 摩頭連接器48係嵌合於主按摩頭60 (第7圖）的內部，同時 由螺絲固定。在主按摩頭連接器4 8固定於主按摩頭6 0內部 的狀態，至柱塞連接器4 6爲止大致收容於主按摩頭6 0的內 部。另外，在柱塞43的另一端部嵌插有彈簧49，該彈簧49 係朝從頭部3突出的方向通常對柱塞4 3、亦即主按摩頭6 0 附加彈力。又，柱塞43的往返運動的敲打，例如約爲6mm。 螺線管組裝體40係相對於內殼L21、R22，被收容於內 • 殼L2；l、R22內所設的螺線管組裝體收容部23內。具體而言， 螺線管組裝體4 0的緩衝橡膠4 5，係利用嵌合於內殼L2 1、 R22的嵌合槽24內，而將螺線管組裝體40安裝於內殼L21、 R22。在內殼L21、R22上形成有通氣孔25，同時，在外殼 LI 1、R12上也形成有通氣孔14(第1圖），從螺線管組裝體 40產生的熱通過此等通氣孔25、14而容易散出至按摩器1 的外部。 主按摩頭60(第7圖）具有，位於內殼L21、R22間，且 1279229 覆蓋外側的橡膠（未圖示）；及收容有上述螺線管組裝體40 的柱塞連接器46、橡膠連接器47與主按摩頭連接器48的空 腔部6 1。該主按摩頭6 0具有隔開間隔對向配置的一對臂 62，在設於一方的臂62內側的轂63上，由螺絲安裝有鉤扣 7 0 (主按摩頭側的被繫合部）。鉤扣7 〇具有選擇性地繫拆嵌 合後述的固定鉤9 0 (繫合部）的桿9 1的前端部側的嵌合槽 70a。由該嵌合槽70a與固定鉤90構成繫合機構。 副按摩頭8 0 (第8圖）係位於主按摩頭的一對臂6 2間， φ 具有覆蓋於外側的橡膠（未圖示）及臂8 1。 在形成於副按摩頭8 0的臂8 1的基端部的貫穿孔8 2，及 形成於主按摩頭60的一對臂62的各基端部的貫穿孔64,插 穿有軸65，利用將該軸65的兩端部插入設於內殼L21、R2 2 的基端側的轂2 6內，可使主按摩頭6 0與副按摩頭8 0被樞 支爲口1相對內殼L21、R22(外殼Lll、R12)自由轉動。藉此， 主按摩頭60與副按摩頭80係以垂直於頭部3的長度方向的 軸爲中心分別可個別地自由轉動。 φ 另外，在軸6 5上，在副按摩頭8 0的臂8 1內側嵌插有 彈簧6 6，該彈簧6 6係沿從主按摩頭6 0的一對臂6 2間朝外 側突出的方向（從頭部3突出的方向）通常對副按摩頭80附 加彈力。又，彈簧6 6在第7圖中顯示在主按摩頭6 0的一對 臂62的內側。另外，在軸65上，在主按摩頭60的臂62與 副按摩頭8 0的臂8 1間的部分，以主按摩頭6 0與副按摩頭 8 0分別個別地平滑地轉動的方式介入墊圈6 7。 在副按摩頭8 0安裝有如第8圖所示零件組成的固定鉤 -14- 1279229 9〇。第9圖顯示此等的立體圖，第1 〇圖顯示前視圖，第1 1 圖顯示俯視圖（上面圖），第1 2圖顯示沿著第1 1圖中的線A -

The present invention has been made in view of the above problems, and provides a massager having a configuration suitable for a portable type and having a small size and a light weight, and φ and a massage interval are significantly changed. (Means for Solving the Problem) In order to achieve the above object, the massager of the present invention has a special part; a sub-massage head provided in such a manner as to change the amount of protrusion protruding from the head; and a driving mechanism for causing the main massage head to perform a massage action The binding head and the sub-massage head that disassemble the sub-massage head freely on the main massage head are disposed in parallel in the longitudinal direction of the head. According to this configuration, the sub-massage head can selectively freely solve the problem of 1), and it is necessary to alternate the number of movements (two) in the massage portion of the moving massage portion. In addition, when it is possible to switch to wide-angle, the wide range is not clear, and the change is used as a case of switching the long-pressing width. The purpose of the change is that the massage range is included: the main massage head and the structure of the head And the optional mechanism; the main massage is removed from the main massage head 1279229 and is placed in parallel in the length direction of the head. Therefore, if the massage is performed while the sub massage head is attached to the main massage head, the massage range becomes The combined length of the main massage head and the sub massage head, if the massage is performed in a state where the sub massage head is not attached to the main massage head, the massage is performed only by the main massage head, and the massage range is tied to the massage head. The condition of the main massage head is short, and the massage range and the massage interval can be clearly changed. The sub-massage head has a movable range larger than the movable range of the massage operation of the main massage head, and the amount of protrusion from the head in the movable range becomes the largest | one end side, preferably equivalent to the de novo within the movable range of the main massage head The protruding amount of the protrusion becomes the largest one end side. Thereby, when the sub massage head is not attached to the main massage head, that is, when only the main massage head performs the massage operation, the sub massage head does not contact the massaged part of the user, and the massage range can be more clearly And the massage interval changes. The main massage head and the sub massage head are respectively rotatably pivotally supported on one end side of the head, and the center of rotation is preferably orthogonal to the longitudinal direction of the head. As a result, the constitution of each massage head can be simplified, and the small size suitable for the portable type can be realized and lightened. The tying mechanism is constituted by a tying portion provided on the sub-massage head, a tying portion provided on the main massage head side of the main massage head, and a tying portion provided on the head side of the head portion.

(Operation Department). The release mechanism is constituted by the release lever link 1 1 〇 and the release operation key n 5 . The lever 1 1 1 for releasing the joystick link 1 10 is inserted into the space 99 formed by the fixed hook 90 and the rod 91 (Fig. 9). Therefore, when the key 1 15 protruding from the outer casing R12 is pressed, the fixing hook 90 resists the elastic force of the spring 9 8 from moving toward the opposite side of the hook 70 by the lever 11. On the other hand, when the rod 91 of the fixing hook 90 is fitted to the fitting groove 70a of the hook 70 (Fig. 13 to Fig. 16, Fig. 19), the sub massage head 80 becomes φ fixed to the main massage head. In the state of 60, when the rod 91 is fitted to the fitting groove 34 (the engaged portion on the head side) formed inside the inner casing R2 2 and the fitting groove 35 5 fitted to the guide rail 35 to be described later, (Fig. 17, Fig. 18, Fig. 20, Fig. 20), the sub massage head 80 is fixed to the inner casing R22. The sub-massage head 80 is a position at which the rod 9 1 is fitted to the fitting groove 34 as an upper limit fixing position, and the position at which the rod 9 1 is fitted to the hook 70 is a lower limit fixed position, and is formed at two fixed positions. Rotate between. In the vicinity of the lower limit fixed position, the rod 91 is fitted to the hook 70, and the sub massage head 80 is coupled to the main massage head 6 1 1 1279229 to be integrally operated. Thereby, the lower limit fixed position ' of the sub-massage head 80 corresponds to - the position at which the amount of protrusion from the head in the movable range of the massage operation of the main massage head 60 becomes the largest. Further, the upper limit fixed position of the sub massage head 80 is set higher than the upper limit position of the movable range of the massage operation of the main massage head 60, and the sub massage head 80 has a larger movable range than the main massage head 60. The movable range. Further, in a state where the rod 9 1 is fitted to the fitting groove 34 or the hook 70, if the key 1 15 is pressed, the fitting can be released. Further, in a state where the rod 9 1 is fitted to the hook 70, if the key 1 1 5 is depressed, the sub-II massage head 80 moves in the direction from the head 3 due to the elastic force of the spring 66, but When the rod 9 1 is disengaged from the hook 70, the fixing hook 90 is abutted against the stopper portion 6 8 (Fig. 7) provided on one arm 62 of the main massage head 60, so the sub massage head 80 does not pass over. The lower limit is fixed and rotated. Specifically, when the rod 9 1 is fitted to the hook 70, the key 1 1 5 is pressed, and if the elastic force of the spring 6 6 is pressed to press the sub-massage head 80 into the head 3, the rod 91 is pressed. The fitting groove 34 is fitted to the inner casing R22. Thereby, the sub massage head 80 is fixed in the inner casing R22, and the sub massage head 80 is locked in the state of most entering the first step 3. In this state, only the main massage head 60 performs a massage operation. On the contrary, when the lever 91 is fitted in the fitting groove 34 of the inner casing R22, the key 1 15 is depressed, and the sub-massage head 80 is rotated in the direction protruding from the head 3 by the elastic force of the spring 66, the lever 9 1 is fitted to the hook 70. Thereby, the sub massage head 80 is fixed to the main massage head 60, and the sub massage head 80 is locked in a state where it is most protruded from the head 3. In this state, the main massage head 60 and the sub massage head 80 perform a pressing operation. Further, when the sub-massage head 80 is moved within the movable range, the inside of the inner casing R 2 2 is provided on the inner side of the inner casing R 2 2 so as to be surely locked at any of the upper or lower fixed positions of the upper -17 to 1279229. Guide rail 3 5. The guide rail 35 is in a state in which the sub-massage head is between the upper limit fixed position and the lower limit fixed position, and the rod 91 of the fixing hook 9 is resisted by the elastic force of the spring 98, and is maintained in a state of being rotated along the opposite side of the hook 7Q. In the state in which the release state is formed in contact with the portion extending in the sheet direction of the rod 9 1 along the fixed hook 9 ', the guide rail 35 constitutes a release maintaining mechanism. Thereby, the key 1 1 5 is pressed from the engagement of the rod 9 1 with the hooking groove 70 or the fitting groove 34 of the inner casing R 2 2 to the released state, and is maintained until the sub-massage head 8 0 reaches any position of the upper limit fixed position or the lower limit fixed position, and the sub massage head 80 is surely locked at any position of the upper limit fixed position or the lower limit fixed position. The guide rail 35 has a fitting groove 35a having a front end portion of the fitting rod 911 at an upper limit fixing position of the sub-massage head 80, and has a rod 91, that is, a pair, together with the fitting groove 34. The massage head 8 〇 is fixed at the upper limit fixed position. On the other hand, the lever 1 1 1 of the release lever link} i 解除 which releases the lock of the fixing hook 90 is formed in an arc shape as shown in FIGS. 13 to 18, which is for suppressing Unwanted torque is generated, and the joystick 1 Π is not close to the position of the fixed hook 90 and is as close as possible to the left and right of the rod support 9 〇a of the fixed hook 9 „ direction, that is, accompanied by the sub massage The rotation between the upper limit fixed position and the lower limit fixed position of the head 80 is rotated, and the fixed hook 90 is rotated by an arcuate path centering on the through hole 82 of the sub massage head 80, and the lever 1 is arranged along the arc shape. The manner of the trajectory is extended. Thereby, the joystick iii is independent of the position of the fixed hook 9 ' 'the central portion of the left and right direction of the rod support 90 a that is in contact with the fixed hook 90 ′ therefore does not produce a fastening hook 9 〇 Unwanted torque at the time. -18- • 1279229 and 'displacement of the lever 1 1 1 when the position of the sub-massage head 80 relative to the fixed hook 9 ( (the position of the sub-massage head 8 )) is moved or stopped The amount does not change, and the pressing operation of the key 1 15 can be a certain force and a certain amount. As a result, the reactivity of the sub-massage head 80 with respect to the fixation and the release of the lock of the key 1 15 can be improved. In the massager 1 thus constructed, the main massage head 60 and the sub massage head 8 are both The massage action can be provided, and the fixing hook 9 is attached to the hook 7 〇, and the auxiliary massage head 80 is fixed on the main massage head 60. At this time, the fixed fishing 90 is combined with the φ inner casing R2 2 . When the slot 3 4 is engaged, if the button 1 1 5 is pressed, the lock is released, and by the elastic force of the spring 6 6 associated with the massage head 80, the sub-massage head 80 rotates in the direction protruding from the head 3, and the hook is fixed. 9 The 〇 is attached to the hook 7 〇. In the normal state when the auxiliary massage head 80 is fixed to the main massage head 60, the main massage head 6 〇 and the sub massage head 80 are connected by the solenoid assembly 4 The spring 49 of 0 protrudes from the head 3 (Fig. 15). Here, when the power switch 7 is turned on, the repulsive force of the plunger 4 3 of the solenoid assembly 40 resists the elastic force of the spring 49. The main massage head 60 and the Φ sub massage head 80 move in the direction of entering the head 3 (Fig. 6). The reciprocating motion of the plunger 4 3 causes the main massage head 60 and the vice The head 80 repeatedly moves in and out of the _ action to perform a massage (knocking action) on the massage part (for example, the shoulder). In the massage action, the main massage head 60 and the sub massage head 80 are arranged in a line in a straight line. Since the length of the portion 3 is in the longitudinal direction, the massage operation can be performed in a linear length range. When the main massage head 60 is to be used only, the sub massage head 80 is pressed into the head 3 by pressing the key 1 1 5 . Then, the state in which the fixing hook 90 is engaged with the hooks 7 0 -19 to 1279229 is brought into a state of being engaged with the fitting groove 34 of the inner casing R2 2, and the sub-massage head 80 is fixed therein. Shell R2 2. In the normal state when the sub-massage head 80 is fixed to the inner casing R22, although the main massage head 60 protrudes from the head 3 by the action of the spring 49 of the solenoid assembly 40, the sub-massage head 80 It remains in the state of entering the head 3 (Fig. 17). When the massager 1 is massaged from the massaged portion such as the shoulder from above, the sub-massage head 80 is pressed into the head portion 3 by merely pressing the release operation key 115. This is to release the lock of the fixed I hook 90 and the hook 70 by the push release operation key 1 1 5 so that the sub massage head 80 and the head 3 are relatively rotatable, and the head 3 is relatively opposite. The sub-massage head 80 supported by the massaged portion such as the shoulder is relatively rotated by its own weight. At this time, the rod 91 of the fixing hook 90 is held by the guide rail 35 until the sub-massage head 80 reaches the upper limit fixing position, and the engagement with the fitting groove 34 of the hook 70 or the inner casing R2 2 is released. status. Thereby, after the engagement of the fixing hook 90 and the hook 70 is released, it is possible to surely move to the state of being engaged with the fitting groove 34 of the inner casing R22. • Here, when the power switch 7 is turned on, as the plunger 43 of the solenoid assembly 40 resists the repulsive force of the spring 49, only the main massage head 60 moves in the direction of entering the head 3 (the first) 1 8 picture). The massage (knocking action) of the massage part (for example, the shoulder) is performed by the entrance and exit operation which is performed only by the main pressing head 60. In this case, the pressing operation is merely provided by the main massage head 6 ,, so that the massage operation is performed only in a short linear range. In this way, according to the massager 1, as long as the key 1 1 5 is pressed to cause the sub-massage head 80 to protrude from the head 3, it can be changed to a wide range of massage action 'If the key is pressed -20- 1279229 % * 1 1 5 Pressing the sub-massage head 80 into the head 3 can change the massage action into a narrow range, so that the massage head extending along the length of the head 3 can be changed (the main massage head 60 and the sub massage head 80) )length. Further, it is possible to adapt to a portable small-sized and lightweight structure, and to realize a configuration in which the massage range and the massage interval are clearly changed.
