  As shown in FIG. 5, the lid 20 includes a pasting surface 21 that is an inner surface to which the pad 30 can be pasted. The pad 30 is affixed to the affixing surface 21 and the lid 20 is closed, whereby the pad 30 is accommodated in the case 10.

  The case 10 includes an opening 11, a side wall 12, a bottom wall 13, and a main body support portion 14 that supports the main body 50. The main body 50 and the main body support portion 14 have a detachable structure. The main body 50 is accommodated in the case 10 by being attached to the main body support portion 14. According to the state in which the main body 50 is attached to the main body support portion 14, the cord insertion opening 11 </ b> A that is a part of the opening 11 is formed between the side wall 12 of the case 10 and the main body 50. Further, the cord housing portion 15 is formed by being surrounded by the main body 50, the side wall 12, and the bottom wall 13. The cord insertion opening 11 </ b> A is connected to the cord housing portion 15.

  In a state where the main body 50 is attached to the main body support portion 14, the cord insertion opening 11 </ b> A is opened or closed as the cover 51 rotates with respect to the main body 50. According to an example, the range in which the cover 51 can rotate with respect to the main body 50 is from a first rotation position that closes the cord insertion opening 11 </ b> A to a second rotation position that faces the front of the operation unit 60 at a predetermined distance. Range. The predetermined distance is, for example, a distance at which the operation unit 60 can be operated by the user 100 (see FIG. 6).

  When the cord insertion opening 11 </ b> A is opened, the cord 70 can be disposed in the cord housing portion 15 from the outside of the case 10. Then, the cord 70 is accommodated in the case 10 by closing the cord insertion opening 11 </ b> A by the cover 51. Thus, the case 10 can accommodate the pad 30, the main body 50, and the cord 70 together.

The operation of the low frequency treatment device 1 will be described with reference to FIGS.
An AC adapter connected to a commercial AC power supply (not shown) is connected to the power connector 52 (see FIG. 4), whereby electric power is supplied to the main body 50 (see FIG. 4). The user 100 peels off the pad 30 from the sticking surface 21 (see FIG. 5), pulls out the cord 70 from the cord housing portion 15 (see FIG. 5), grasps the second element 42 of the grasping portion 40 with the palm of the hand, The pad 30 is attached. The user 100 can select the usage form of the low frequency treatment device 1 (see FIG. 1) by selecting the target region.

  FIG. 6 shows a first usage pattern. In the first usage pattern, the pad 30 is attached to the neck and the shoulder. FIG. 7 shows a second usage pattern. In the second usage pattern, the pad 30 is attached to the upper portion of the portion around the scapula. FIG. 8 shows a third usage pattern. In the third usage pattern, the pad 30 is attached to the lower part of the part around the scapula.

  The portion around the scapula is curved according to the shape of the scapula. The shape of the pad 30 is set to an arc shape based on such a body shape. For this reason, it is easy to fit the pad 30 to the upper part and the lower part which are parts around the scapula. For this reason, an electric current flows intensively around the shoulder blades, and the effect of improving the shoulder stiffness is easily enhanced. In addition, since the recess 30A is formed in the pad 30, the pad 30 is easy to fit on the body even if the target site is a curved site such as the neck and shoulder.

  Thus, according to the low-frequency treatment device 1, the pad 30 is a target even when any of the first usage pattern, the second usage pattern, and the third usage pattern is selected. It is easy to fit a part. For this reason, it is possible to flow a current intensively from the pad 30 to various parts of the body, thereby further enhancing the effect of improving the stiff shoulders.

An opening 11 (see FIG. 1) of the case 10 is closed by a lid 20 (see FIG. 1).

  When the body shape of the user 100 is different from the standard body shape, the wearing state of the pad 30 may not match the preferred wearing state. However, even in such a case, according to the pad 30 designed to fit the portion around the scapula, the scapula is compared with a conventional pad that does not reflect the intention. Easy to fit around. For this reason, regardless of the body shape of the user 100, the degree of contribution related to flowing current intensively around the scapula is higher than that of the conventional pad. This means that the effect of improving the stiff shoulder is relatively enhanced as compared with the conventional pad.

According to the low frequency treatment device 1 of the embodiment, the following effects can be further obtained.
(1) The first width WA is narrower than the second width WB.

  (2) The low frequency treatment device 1 includes a grip 40 attached to the end of the pad 30. For this reason, when the pad 30 is attached to the body, the grip portion 40 is pulled, and the pad 30 is peeled off from the body in order from the end side of the pad 30. For this reason, compared with the case where the pad 30 is peeled off from the intermediate part, the user 100 is easy to peel off the pad 30 from the body.

  (3) The area of the first element 41 occupying the output surface 31 is smaller than the area of the second element occupying the non-output surface 32. For this reason, compared with the case where the area of the 1st element 41 which occupies for the output surface 31 is larger than the area of the 2nd element 42 which occupies for the non-output surface 32, the part which can be mounted | worn to the body of the output surface 31 The area of is wide. For this reason, an electric current can be sent over the wide range in the part around a scapula. In addition, as compared with the case where the area of the second element 42 occupying the non-output surface 32 is smaller than the area of the first element 41 occupying the output surface 31, the user 100 grips when the pad 30 is peeled off. The area of the second element 42 is large. For this reason, it is easy for the user 100 to peel off the pad 30 from the body.

  (4) The sticking surface 21 that is the inner surface of the lid 20 functions as an element for housing the pad 30. For this reason, it is not necessary to form a dedicated structure for housing the pad 30 in the case 10 itself. For this reason, the possibility that the space in the case 10 becomes narrow due to the presence of the structure is avoided.

  (5) The cord 70 can be placed in the cord housing portion 15 from the outside of the case 10 in a state where the main body 50 is supported by the main body support portion 14 and the cord insertion port 11A is opened. The cord insertion opening 11 </ b> A is closed by the cover 51 of the main body 50, thereby preventing the cord 70 from jumping out of the case 10.
