Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dryer in which an attachment can be attached to the outlet of the dryer body.

Some hair dryers have attachments of various shapes that can be attached to the outlet of the dryer body. Among such hair dryers, there is one in which an attachment can be attached to and detached from the dryer body by magnetic force (see, for example, Patent Document 1). In the hair dryer described in Patent Document 1, a magnet is embedded in one of the front end of the dryer main body and the rear end of the attachment, and a magnetic body is attached to the other. The attachment is detachably attached to the dryer body by the magnetic force between the magnet and the magnetic body.

JP 2015-13127

However, depending on how the user uses the dryer, the attachment may be left unattached from the dryer body. In that case, the magnetic force of the embedded magnet is reduced, causing a problem that the attachment tends to come off from the dryer main body. Therefore, it becomes necessary to replace the dryer body or attachment in which the magnet is embedded.
Furthermore, even if the user wants to use other commercially available attachments, they often cannot be attached to the dryer body because the size does not match. Therefore, it is not possible to use attachments other than dedicated attachments that match the size of the dryer main body in advance.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hair dryer that does not require replacement of the main components even after long-term use and that allows the use of various attachments.

In order to solve the above problems, a hair dryer according to one aspect of the present invention comprises:
a dryer main body comprising a channel having a gas suction port and a gas outlet, a gas flow section for causing the gas in the channel to flow, and a gas heating section for heating the gas in the channel;
an attachment having an internal space having a gas inlet and a gas outlet;
One end side is attached to the gas outlet side of the dryer main body, and the other end side is attached to the gas inlet side of the attachment, and the flow path of the dryer main body and the internal space of the attachment are communicated. an adapter with a connection space;
with
a magnet is fixed to the adapter;
A magnetic member is fixed to the gas inlet side of the attachment, and the adapter is detachably attached to the attachment by magnetic force,
The adapter is detachably attached to the dryer body by magnetic force or a mechanical attachment/detachment mechanism.

As described above, according to the present invention, it is possible to provide a hair dryer that can be used with various attachments without requiring replacement of the main members even after long-term use.

(Hair dryer according to the first embodiment of the present invention)
First, a hair dryer 2 according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. FIG. 1 is a side sectional view schematically showing a hair dryer according to a first embodiment of the invention. FIG. 2 is a perspective view schematically showing the attachment/detachment structure of the dryer main body, adapter and attachment of the hair dryer according to the first embodiment of the present invention.

A hair dryer 2 according to this embodiment includes a dryer body 10 , an adapter 20 and an attachment 30 . All of them have outer shells 10C, 20C, and 30C made of resin. The dryer body 10 comprises a channel 12 having a gas inlet 10A and a gas outlet 10B. Further, the dryer main body 10 includes a gas flow section that causes the gas within the flow path 12 to flow, and a gas heating section that heats the gas within the flow path 12 . In this embodiment, a fan 40 driven by an electric motor is used as the gas flow section, and a heater 42 that generates heat by electrical resistance is used as the gas heating section. However, it is not limited to this, and any device or member for flowing gas can be adopted as the gas flow section, and any device or member for heating gas can be adopted as the gas heating section. can. The dryer body 10 is provided with a grip portion 16 .

The attachment 30 of this embodiment comprises an interior space 32 having a gas inlet 30A and a gas outlet 30B. The gas ejection port 30B of this embodiment has a shape of a flat nozzle elongated in the direction perpendicular to the paper surface. One end 20A of the adapter 20 contacts the end of the dryer body 10 on the side of the gas outlet 10B, and the other end 20B contacts the end of the attachment 30 on the side of the gas inlet 30A. In this state, the adapter 20 has a connecting space 22 that allows the channel 12 of the dryer body 10 and the inner space 32 of the attachment 30 to communicate with each other.

A ring-shaped magnet 24 is attached to the adapter 20 so as to surround the outer periphery of the connection space 22 . In other words, the magnet 24 is continuously provided on the circumference along the contour of the outer shell portion 20C of the adapter 20. As shown in FIG. Magnet 24 is exposed at both one end 20A and the other end 20B. However, the magnet 24 does not necessarily have to be exposed, and the surface of the magnet 24 may be covered with the outer shell portion 20C of the adapter 20 as long as sufficient magnetic force is generated. Moreover, the adapter 20 is not limited to one in which the ring-shaped magnet 24 is arranged in the outer shell portion 20C made of resin. For example, the adapter 20 may be formed by covering the outer surface of the ring-shaped magnet 24 except for the exposed surface without the outer shell portion with a protective layer.

A ring-shaped magnetic member 14 is attached to the end of the dryer main body 10 on the side of the gas outlet 10</b>B so as to surround the outer periphery of the flow path 12 . In other words, the magnetic member 14 is provided continuously along the circumference of the outer shell portion 10C of the dryer body 10 .
A magnetic member 34 is attached to the end of the attachment 30 on the side of the gas inlet 30</b>A so as to surround the outer periphery of the internal space 32 . In this embodiment, six magnetic members 34 are arranged at equal intervals on the circumference. In other words, the magnetic members 34 are intermittently provided along the outer shape of the outer shell portion 30</b>C of the attachment 30 .
The magnetic members 14 and 34 can be exemplified by being made of an iron- or steel-based material.

The magnet 24 of the adapter 20 attracts the magnetic member 14 of the dryer body 10 and the magnetic member 34 of the attachment 30 , whereby the attachment 30 is detachably attached to the dryer body 10 via the adapter 20 . The magnetic force of the magnet 24 of the adapter 20 joins the dryer body 10, the adapter 20 and the attachment 30 together. In the hair dryer 2 to which such an attachment 30 is attached, hot air or cold air can be blown out from the gas outlet 30B of the attachment 30 by the fan 40 or the heater 42 . Since it is attached by magnetic force, the attachment 30 can be easily removed. Various other types of attachments 30 having magnetic members 34 can also be detachably attached to the dryer main body 10 via the adapter 20 by magnetic force.

Even if the magnetic force of the magnet 24 attached to the adapter 20 deteriorates, if only the adapter 20, which is cheaper than the dryer body 10 and the attachment 30, is replaced, the dryer body 10 and the attachment 30, which are main members, can be replaced. The hair dryer 2 can be used continuously for a long period of time.
Moreover, in this embodiment, not only the dedicated attachment 30 but also various commercially available attachments can be used. In this case, for example, the magnetic member can be adhered or adhered to the end of a commercially available attachment using a heat-resistant adhesive or double-sided tape. If the size of the commercially available attachment is significantly different from the size of the dryer main body 10, various commercially available attachments can be used by using the adapter 20 with the other end 20B of the attachment having a different size. can be done.

As described above, the hair dryer 2 according to the present embodiment includes the channel 12 having the gas suction port 10A and the gas outlet 10B, the gas flow section 40 for causing the gas in the channel 12 to flow, and the gas in the channel 12. , an attachment 30 having an internal space 32 having a gas inlet 30A and a gas discharge port 30B, and one end 20A of the dryer main body 10 on the gas outlet 10B side , and the other end 20B contacts the end of the attachment 30 on the side of the gas inlet 30A, and the adapter 20 having a connection space 22 that communicates the flow path 12 of the dryer body 10 and the internal space 32 of the attachment 30 A magnet 24 is attached to the adapter 20, and magnetic members 14 and 34 are attached to the end of the dryer main body 10 on the side of the gas outlet 10B and the end of the attachment 30 on the side of the gas inlet 30A. 30 is detachably attached to the dryer main body 10 via an adapter 20. - 特許庁

Accordingly, it is possible to provide the hair dryer 2 that can be used with various attachments without requiring replacement of the main members even after long-term use.
Furthermore, as described above, when the same magnet 24 provided in the adapter 20 attracts the magnetic member 14 of the dryer body 10 and the magnetic member 34 of the attachment 30, a thin and compact adapter 20 can be realized. As a result, the size of the entire hair dryer 2 can also be reduced.

As is clear from FIG. 2, the magnetic member 14 of the dryer body 10 is continuously provided on the circumference, and the magnetic member 34 of the attachment 30 is intermittently provided on the circumference. Therefore, the magnetic member 14 has a larger bonding area due to the magnetic force than the magnetic member 34 . Therefore, the magnetic force between the dryer main body 10 and the adapter 20 is stronger than the magnetic force between the adapter 20 and the attachment 30 . Thus, when the user attaches and detaches the attachment 30, it is possible to avoid an uncertain state in which it is unclear whether the dryer body 10 and the adapter 20 are disconnected or the adapter 20 and the attachment 30 are disconnected. . In this embodiment, the attachment 30 can be easily attached and detached while the adapter 20 is always attached to the dryer main body 10 .

Since the magnetic force between the dryer body 10 and the adapter 20 is stronger, a state in which the adapter 20 is attached to the dryer body 10 is naturally formed. Therefore, even when the attachment 30 is removed, the magnet 24 of the adapter 20 always attracts the magnetic member 14 of the dryer body 10 without requiring any special operation. Therefore, when attracting the magnetic members 14 and 34 of the dryer main body 10 and the attachment 30 with one magnet 24, deterioration of the magnetic force of the magnet 24, which is the only magnet, can be reliably suppressed.

<Modification 1 of detachable structure>
Next, modification 1 of the detachable structure of the dryer main body 10, the adapter 20 and the attachment 30 of the hair dryer 2 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 3 is a perspective view schematically showing Modification 1 of the attachment/detachment structure of the dryer main body, the adapter and the attachment of the hair dryer according to the first embodiment of the present invention.
The modification 1 is different in that the magnets 24 of the adapter 20 are not continuously provided on the circumference as in the above embodiment, but intermittently provided on the circumference. Another difference is that the number of magnetic members 34 of the attachment 30 intermittently provided on the circumference is smaller than in the above embodiment.

Since the number of magnetic members 34 of attachment 30 is reduced, the magnetic force between dryer body 10 and adapter 20 is stronger than the magnetic force between adapter 20 and attachment 30 .
In addition, since the magnet 24 of the adapter 20 and the magnetic member 34 of the attachment 30 are both intermittently provided on the circumference, the attachment 30 can be attached to the adapter only when the positions of the magnet 24 and the magnetic member 34 coincide in the circumferential direction. 20 can be connected. Therefore, the adapter 20 and the attachment 30 can be positioned in the circumferential direction without requiring a special positioning member.

<Modification 2 of detachable structure>
Next, modification 2 of the detachable structure of the dryer body 10, the adapter 20 and the attachment 30 of the hair dryer 2 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 4 is a side cross-sectional view schematically showing Modification 2 of the attachment/detachment structure of the dryer main body, the adapter and the attachment of the hair dryer according to the first embodiment of the present invention.
In modification 2, one end 20A and the other end 20B of the adapter 20 have different diameters, and separate magnets 24A and 24B are attached to the one end 20A and the other end 20B, respectively. It differs from the above-described embodiment in that

The magnet 24A at one end 20A attracts the magnetic member 14 of the dryer body 10, and the magnet 2B at the other end 20B attracts the magnetic member 34 of the attachment 30. FIG. Thereby, the dryer main body 10, the adapter 20 and the attachment 30 are integrally joined.
The attachment 30 shown in Modification 2 is a diffuser type attachment having a large number of fine holes 32 as an internal space. The attachment 30 is provided with a plurality of projecting shapes 36, and holes 32 are also formed in the projecting shapes 36. - 特許庁With such a structure, when the fan 40 is operated, air with a moderately suppressed flow rate can be uniformly sent from the gas outlet 30B of the attachment 30 to the whole.

As described above, in Modification 2, the individual magnets 24A and 24B provided in the adapter 20 attract the magnetic members 14 and 34 of the dryer main body 10 and the attachment 30, respectively. As a result, even if the attachment 30 is different in size from the dryer body 10, the attachment 30 can be reliably attached to the dryer body 10 via the adapter 20 in a detachable state by magnetic force.

For example, by making the number of magnets 24A on one end 20A greater than the number of magnets 2B on the other end 20B, the magnetic force between the dryer body 10 and the adapter 20 is reduced to the magnetic force between the adapter 20 and the attachment 30. can be made stronger. However, the magnetic force between the dryer body 10 and the adapter 20 can be adjusted by adjusting the number and size of the magnetic members 14 of the dryer body 10 and the number and size of the magnetic members 34 of the attachment 30. can be stronger than the magnetic force between adapter 20 and attachment 30 .

As described above, the magnet 24 provided in the adapter 20 and the magnetic members 14 and 34 provided in the dryer main body 10 and the attachment 30 are continuously or intermittently provided on the circumference,
The magnetic force between the dryer body 10 and the adapter 20 and the magnetic force between the adapter 20 and the attachment 30 can be arbitrarily set.

(Hair dryer according to the second embodiment of the present invention)
Next, a hair dryer according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a side sectional view schematically showing a hair dryer according to a second embodiment of the invention. FIG. 6 is a perspective view schematically showing the attachment/detachment structure of the dryer main body and the adapter of the hair dryer according to the second embodiment of the present invention.
This embodiment differs from the above-described first embodiment in that the adapter 20 is attached to the dryer main body 10 not by magnetic force but by a mechanical attachment/detachment mechanism. Attachment/detachment between the adapter 20 and the attachment 30 is performed by the magnetic force of the magnet 24 of the adapter 20, as in the first embodiment.

The mechanical attachment/detachment mechanism is mainly composed of grooves 18 provided on the outer surface of the dryer body 10 and projections 26 provided on the inner surface of the adapter 20 . The width dimension of the groove portion 18 is slightly larger than the outer dimension of the projection portion 26 in plan view. The inner diameter of the adapter 20 is slightly larger than the outer diameter of the dryer main body 10, so that the adapter 20 and the dryer main body 10 are fitted together.
The groove portion 18 provided on the outer surface of the dryer body 10 extends axially for a predetermined length from the end on the gas outlet 10B side toward the gas suction port 10A side, and then advances in a direction intersecting the axial direction and terminates. ing. It is preferable that the length extending in the direction intersecting the axial direction is longer than the external shape of the protrusion 26 of the adapter 20 in plan view.

When the adapter 20 is attached to the dryer 10, the projection 26 is aligned with the opening of the groove 18 in the circumferential direction, and the adapter 20 is axially slid toward the gas inlet 10A. After that, the adapter 20 and the dryer main body 10 are relatively rotated in the circumferential direction so that the protrusions 26 are aligned with the grooves 18 , and the protrusions 26 are arranged in the region of the grooves 18 in the direction intersecting the axial direction. The adapter 20 can be securely attached to the dryer 10 by restraining the protrusions 26 by the grooves 18 . Moreover, the adapter 20 can be easily removed from the dryer 10 by reversing the procedure described above.

As in the first embodiment, the adapter 20 and the attachment 30 can be connected by attracting the magnetic member 34 of the attachment 30 with the magnetic force of the magnet 24 provided in the adapter 20 .

As described above, in the second embodiment, the adapter 20 is attached to the dryer main body 10 by the mechanical attachment/detachment mechanisms 18 and 26 . A magnet 24 is attached to the adapter 20, and a magnetic member 34 is attached to the end of the attachment 30 on the gas inlet 30A side. be done.
Therefore, in the hair dryer 2 according to the second embodiment, the adapter 20 can be reliably attached to the dryer main body 10 by the mechanical attachment/detachment mechanisms 18 and 26, and the magnetic force of the magnet 24 of the adapter 20 can easily The attachment 30 can be detachably attached to the dryer body 10 via the adapter 20 .

In the second embodiment as well, since the dryer main body 10 and the attachment 30 are not provided with magnets, even if the magnetic force of the magnet 24 deteriorates, the dryer, which is the main member, can be replaced by replacing only the adapter 20. The hair dryer 2 can be used continuously for a long time without exchanging the main body 10 and the attachment 30. - 特許庁Various attachments can also be used using the adapter 20 .

(Hair dryer according to the third embodiment of the present invention)
A hair dryer according to a third embodiment of the present invention will now be described with reference to FIGS. 7, 8A, 8B and 9. FIG. FIG. 7 is a side cross-sectional view schematically showing a detachable structure of a dryer main body, an adapter and an attachment of a hair dryer according to a third embodiment of the present invention. 8A is a side view showing the arrow AA in FIG. 7. FIG. 8B is a side view showing the arrow BB in FIG. 7. FIG. FIG. 9 is a side cross-sectional view schematically showing a hair dryer according to a third embodiment of the present invention in which the dryer main body, adapter and attachment shown in FIG. 7 are assembled. 8A and 8B show not only the portion corresponding to the cross section of FIG. 7 but also the entire circumferential direction.

In the hair dryer according to the above-described embodiment, magnets and magnetic members are arranged on the periphery along the outer shape of the outer shell portions 10C, 20C, and 30C so as to surround the outer periphery of the flow path. This embodiment differs from the above embodiment in that the magnet 24 and the magnetic member 34 are arranged substantially in the center of the flow path. In this embodiment, the adapter 20 is attached to the attachment 30 by magnetic force, and the adapter 20 is attached to the dryer body 10 by a mechanical attachment/detachment mechanism. The connecting area of the dryer body 10, the adapter 20 and the attachment 30 has a substantially circular cross-sectional shape. However, the shape is not limited to this, and may be an elliptical shape, an oval shape, or a polygonal shape with curved corners.

First, a mechanism for attaching and detaching the adapter 20 and the attachment 30 by magnetic force will be described. The adapter 20 is formed with a magnet holding portion 28 having a first central member 28A positioned substantially in the center of the flow path and three first arm portions 28B radially extending from the first central member 28A. It is The magnet 24 is fixed to the first central member 28A, and the outer ends of the three first arm portions 28B are connected to the outer shell portion 20C of the adapter 20. As shown in FIG. A space between the three radially extending first arm portions 28B serves as a gas flow path and constitutes part of the connection space 22 .

The attachment 30 has a magnetic member holding portion 38 having a second central member 38A positioned substantially in the center of the flow path and three second arm portions 38B radially extending from the second central member 38A. formed. The magnetic member 34 is fixed to the second central member 38A, and the outer ends of the three second arm portions 38B are connected to the outer shell portion 30C of the attachment 30. As shown in FIG. A space between the three radially extending second arm portions 38B serves as a gas flow path and constitutes part of the internal space 32 .

The end face of the magnet 24 fixed to the first central member 28A of the adapter 20 on the side of the attachment 30 is located at the other end 20B of the adapter 20 . The adapter 20 side end of the magnetic member 34 fixed to the second central member 38A of the attachment 30 is positioned at the gas inlet 30A of the attachment 30 . As a result, the adapter 20 and the attachment 30 are detachably connected by magnetic force while the magnet 24 and the magnetic member 34 are in contact with each other.
Further, a peripheral wall portion 38A1 is formed around the second central member 38A of the attachment 30. As shown in FIG. By enclosing the outer surface of the first central member 28A of the adapter 20 in contact with the inner surface of the peripheral wall portion 38A1, positioning between the adapter 20 and the attachment 30 can be performed. This provides a compact positioning mechanism.

Next, a mechanical mechanism for detachably connecting the adapter 20 and the dryer body 10 will be described. A stepped insertion portion 29 having a slightly smaller outer diameter is formed from one end portion 20A of the adapter 20 toward the dryer main body. On the other hand, in the region of the dryer main body 10 on the side of the gas outlet 10B, a stepped inserted portion 19 having a slightly widened inner diameter is formed. The outer diameter of the insertion portion 29 and the inner diameter of the inserted portion 19 are substantially the same. Therefore, as shown by the arrow in FIG. The adapter 20 and the dryer main body 10 are connected by a fitting structure (so-called spigot connection structure) as shown. The insertion portion 29 and the inserted portion 19 as described above constitute a mechanical attachment/detachment mechanism of the present embodiment.

For example, the adapter 20 and the dryer main body 10 can be strongly joined by an interference fit in which the outer diameter of the insertion portion 29 is slightly larger than the inner diameter of the inserted portion 19 . When the adapter 20 and the dryer main body 10 are made of a resin material, the adapter 20 can be removed from the dryer main body 10 relatively easily because the adapter 20 and the dryer main body 10 are elastically deformed. In particular, the adapter 20 can be removed from the dryer main body 10 with a relatively small force by pushing the side surface of the adapter 20 so that it is slightly recessed. In this embodiment, the insertion portion 29 is formed in the adapter 20 and the inserted portion 19 is formed in the dryer main body 10, but the present invention is not limited to this. may be formed, and an insertion portion may be formed in the dryer body 10 .

The cross-sectional shape of the mating portion of the adapter 20 and the dryer main body 10 is not circular, but is shaped such that the outer shape and the inner shape change in the circumferential direction, and the adapter 20 and the dryer main body 10 are relatively rotated to fix them together. It is also possible to employ an attachment/detachment mechanism that has a rotational position where it is held and a rotational position where there is a gap therebetween. Furthermore, an attachment/detachment mechanism composed of the groove portion 18 and the projection portion 26 as in the second embodiment can also be employed.
The mechanical attachment/detachment mechanism is not limited to the fitting structure (so-called spigot connection structure) shown in FIG. Any other mechanical attachment/detachment mechanism can be employed.

The number of arm portions 28B (38B) radially extending from the central member 28A (38A) is not limited to three. There may be two cases, and there may be cases where there are four or more. In order to obtain sufficient strength and secure a larger gas flow path, the cross-sectional shape of the arm portion 28B (38B) is such that the dimension in the direction parallel to the gas flow is longer, and the arm portion perpendicular to the gas flow is longer. A small width dimension is preferred. In this embodiment, the three arm portions 28B (38B) are evenly arranged in the circumferential direction at intervals of approximately 120 degrees, but the present invention is not limited to this. By varying the arrangement of the arm portions 28B (38B), the gas flow can also be changed according to the application.

In this embodiment, in order to reduce gas flow resistance, the circumferential positions of the first arm portion 28B of the adapter 20 and the second arm 38B of the attachment 30 are matched, but the present invention is not limited to this. . Circumferential positions of the first arm portion 28B and the second arm 38B can also be varied. Also, the number of the first arm portions 28B of the adapter 20 and the number of the second arms 38B of the attachment 30 can be varied. Further, the first arm portion 28B and the second arm 38B have curved surfaces like fan blades, so that the gas flow can be swirled.

In this embodiment, the adapter 20 and the dryer main body 10 are connected by a mechanical attachment/detachment mechanism, but it is not limited to this. A central member to which a magnetic member 14 is attached and a plurality of arms extending radially from the central member are provided on the gas outlet 10B side of the dryer main body 10, and the outer ends of the radially extending arms serve as the dryer. It can also be formed so as to be connected to the outer shell portion 10C of the main body 10 . Thereby, the adapter 20 and the dryer main body 10 can also be detachable by the magnetic force between the magnet 24 and the magnetic member 14 .

In this case, it is conceivable to use different magnets 24A and 24B on the dryer main body 10 side and the attachment 30 side. In that case, the size of the magnets 24A and 24B, the number of installation, etc. can be adjusted to make the magnetic force with the dryer main body 10 stronger than the magnetic force with the attachment 30. FIG.
It is also conceivable to use one magnet 24, for example, a truncated cone whose surface on the side of the dryer body 10 is larger than the surface on the side of the attachment 30. FIG. Thereby, the magnetic force with respect to the dryer main body 10 can be made stronger than the magnetic force with respect to the attachment 30 . This prevents the adapter 20 from coming off the dryer body 10 when the attachment 30 is attached or detached.

As described above, in this embodiment, the adapter 20 has the first central member 28A to which the magnet 24 is fixed and the plurality of first arm portions 28B radially extending from the first central member 28A. The outer end of the radially extending first arm portion 28B is connected to the outer shell portion 20C of the adapter 20, and the attachment 30 includes a second central member 38A to which the magnetic member 34 is fixed, It has a plurality of second arm portions 38B radially extending from the second central member 38A, and the outer ends of the radially extending second arm portions 38B are connected to the outer shell portion 30C of the attachment 30. Gas flows through the space between the plurality of first arm portions 28B and the space between the plurality of second arm portions 38B.

As a result, outside air is sucked through the suction port 10A by the fan 40 provided in the dryer main body 10, and the gas flows through the flow path 12 and flows out into the adapter 20 through the gas outlet 10B. The gas that has flowed into the adapter 20 from one end 20A flows through the connection space 22 including the space between the three first arm portions 28B, and flows out from the other end 20B to the attachment 30. The gas that has flowed into the attachment 30 from the gas inlet 30A flows through the internal space 32 including the space between the three second arm portions 38B, and is blown out from the gas outlet 30B.

In the present embodiment, since the magnet 24 and the magnetic member 34 are arranged substantially in the center of the adapter 20 and the attachment 30, the pair of the magnet 24 and the magnetic member 34 can easily and reliably connect the attachment 30 to the adapter 20. can be attached and detached. Since the magnet 24 and the magnetic member 34 are positioned substantially in the center, the user can attach and detach the adapter 20 and the attachment 30 without worrying about their relative rotational positions. Furthermore, by positioning both the adapter 20 and the attachment 30 at approximately the center position, a compact positioning mechanism can be realized.
