When the user picks up the cleaning tool 1, for example, to clean a vertically narrow space, the first head region 119 including the magnet as the weight 153 is moved downward, the cleaning head 3 stands upright, and the weight 153 as the magnet and the head fixing magnet 181 are attracted to each other, so that the upright state of the cleaning head 3 can be fixed. Further, since the holder 5 is made of stainless steel as a non-magnetic body, it is configured such that: the weight 153 as a magnet does not attract the holder 5 itself, and the weight 153 as a magnet attracts only the protruding head fixing magnet 181.

The cleaning tool handle 7 is configured to: the link 301, the first handle portion 307, the second handle portion 309, the third handle portion 311, and the fourth handle portion 313 having the grip portion 315 are connected in this order, and the link 301, the first handle portion 307, the second handle portion 309, the third handle portion 311, and the fourth handle portion 313 can be switched to the connected state and the separated state.

The link 301 has a handle rotation axis RA for rotating the cleaning tool handle 7 in a predetermined direction₃The rotating portion of (2) is constituted by a pair of first joint portions 303 and second joint portions 305. The first joint portion 303 is coupled to the shank coupling portion 203, and the second joint portion 305 is coupled to the first shank portion 307.

The link 301 (cleaning tool handle 7) and the handle connecting portion 203 of the holder 5 can be on the holder virtual plane IS by the link 301 (cleaning tool handle 7)_BUp rotation (i.e., handle rotation axis RA)₃And the virtual surface IS of the bracket_BOrthogonal) are connected.

When the user uses the cleaning tool 1, the user puts his or her hands into the recessed portions 173 disposed on both side surfaces in the longitudinal direction L of the cleaning head 3 in the closed state to unfold the cleaning head 3 in the unfolded state, and as shown in fig. 6, the cleaning head 3 in the unfolded state is disposed on the cleaning sheet 31 such that the first inner surface 129 and the second inner surface 139 of the nip portion 123 (the first nip portion 125 and the second nip portion 135) face upward.

Next, as shown in fig. 7, the one end 33 of the cleaning sheet 31 is fixed to the second slit portion 165 of the second nip portion 135, and then, as shown in fig. 8, the first nip portion 125 is placed on the second nip portion 135 so as to sandwich the one end 33 of the cleaning sheet 31, thereby deforming the nip portion 123 into the closed state. In the cleaning head 3 in the closed state, the one end 33 of the cleaning sheet 31 is fixed by the second slit portion 165 and the nip portion 123 (specifically, the attraction force between the weight 153 as a magnet and the head fixing magnet 181).

Next, as shown in fig. 9, the user fixes the other end portion 35 of the cleaning sheet 31 in the two first slit portions 163 disposed on the first outer surface 127 of the first clamping portion 125.

When a user cleans a wide space, the cleaning tool 1 is set to a wide space cleaning mode as shown in fig. 10, and the surface to be cleaned can be cleaned without any particular limitation. The surface to be cleaned is cleaned by using the first surface 37 (the surface on the first cleaning surface 113 side of the cleaning head 3) of the cleaning sheet 31, and when the first surface 37 becomes dirty, the cleaning head 3 can be rotated 180 ° to clean the surface to be cleaned by using the second surface 39 (the surface on the second cleaning surface 115 side of the cleaning head 3) of the cleaning sheet.

When cleaning a narrow space, for example, a vertical narrow space 51 as shown in fig. 11, the user can rotate the cleaning tool 1 to a narrow space cleaning mode, specifically, rotate the cleaning head 3 so that the planar direction (not shown) of the cleaning head 3 coincides with the holder virtual surface (not shown) of the holder 5, and extend the end in the longitudinal direction L of the cleaning head 3 (preferably, the end on the side where the opening 117a of the holder hole 117 does not exist) into the narrow space, thereby cleaning the surface to be cleaned in the narrow space.

In order to change the form of the cleaning tool 1 from the wide space cleaning form to the narrow space cleaning form, the cleaning tool 1 may be simply lifted. When the cleaning tool 1 (cleaning head 3) is picked up, since the center of gravity of the cleaning head 3 is located in the first head region 119, it is easy to erect the cleaning head 3 so that the first head region 119 faces downward.

When the cleaning head 3 is erected with the first head region 119 facing downward, the head fixing magnet 181 protruding toward the opposite side of the handle connecting portion 203 of the holder 5 at a position facing the weight 153 on the head connecting portion 201 of the holder 5 and the weight 153 (magnet) are attracted to each other, whereby the upright state of the cleaning head 3 can be fixed.

In the cleaning tool of the present invention (used in the present invention), a cleaning head for cleaning without mounting a cleaning sheet, a cleaning head for cleaning with mounting a cleaning sheet, and the like can be given as the cleaning head.

Examples of the cleaning head for cleaning without mounting a cleaning sheet include a cleaning head having a brush portion, a cleaning head having a sponge portion, and the like.

Examples of the cleaning sheet for the cleaning head to which the cleaning sheet is attached for cleaning include cleaning sheets known in the art, for example, a cleaning sheet containing nonwoven fabric, a cleaning sheet containing fiber bundles (tow), and the like. The cleaning sheet may be dry or wet impregnated with a chemical solution.

The cleaning sheet may be configured as a cleaning sheet having one end portion and the other end portion, and the one end portion and the other end portion may be fixed to a cleaning head. The cylindrical cleaning sheet is preferably used for a cleaning head to be grasped with one hand, which will be described later.

In the cleaning tool of the present invention, the cleaning head is formed in a plate-like shape having a plane direction and a thickness direction, and has a cleaning surface extending in a direction parallel to the plane direction and a head rotation member mounting portion having a head rotation axis extending in a direction parallel to the plane direction. The head rotation shaft is a rotation shaft for rotating the cleaning head with respect to the head rotation member.

The plate-like shape is not particularly limited as long as it has two surface portions extending in a direction parallel to the planar direction and facing each other, and a side surface portion extending in a direction parallel to the thickness direction. The shape of the surface portion as viewed in the thickness direction of the cleaning head may be a polygon such as a triangle (e.g., an isosceles triangle), a quadrangle (e.g., a rectangle, a rhombus), a pentagon, a hexagon, or the like; curved, e.g., circular, elliptical, etc. The plate-like shape may have a longitudinal direction and a width direction in the plane direction.

The surface portion and the side surface portion may be not only flat surfaces but also curved surfaces (for example, curved surfaces in which central regions other than both ends protrude outward and curved surfaces in which central regions other than both ends are recessed inward), and may include an uneven structure such as one or more convex portions and one or more concave portions. Thus, when the cleaning head is configured to hold the cleaning sheet, the cleaning sheet attached to the cleaning head is less likely to be displaced, and the cleaning sheet is less likely to fall off from the cleaning head when the cleaning tool is used.

In the cleaning tool of the present invention, the cleaning head may be configured to have a cleaning surface by only one of the two surface portions (single surface, i.e., only the first cleaning surface), and may be configured to have a cleaning surface by two surface portions (double surfaces, i.e., the first cleaning surface and the second cleaning surface).

In the cleaning tool of the present invention (used in the present invention), the thickness (length in the thickness direction) of the cleaning head is not particularly limited, but it is preferable that the thickness is small from the viewpoint of cleaning a narrow space, and the thickness is preferably 3.0cm or less, and more preferably 2.0cm or less. From the viewpoint of the strength of the cleaning tool, the thickness is preferably 0.1cm or more, and more preferably 1.0cm or more. Further, the thickness of the cleaning head refers to the thickness of the thickest part of the cleaning head.

In the cleaning tool of the present invention, when the cleaning head is divided into the first head region and the second head region by the head rotation axis passing through the head rotation member connecting portion and the virtual surface extending in the thickness direction of the cleaning head, the center of gravity of the cleaning head can be located in the first head region by the cleaning head. In the cleaning tool, it is preferable that the center of gravity of the cleaning head is arranged such that: in a state where the head rotation axis of the cleaning head is held in the horizontal direction and the cleaning head is not fixed, the first head region of the cleaning head moves downward, and the second head region of the cleaning head moves upward. This is from the viewpoint of vertical cleanability and vertical narrow space cleanability.

The centre of gravity of the cleaning head can be adjusted by changing the mass of the components etc. constituting the cleaning head in the first head region and the second head region.

Further, the center of gravity of the cleaning head can be adjusted by disposing an additional member, such as a counterweight, in the first head region. Examples of the material of the weight include metals (e.g., iron, stainless steel, lead, copper, and magnet), rubber, and plastics.

In the cleaning tool of the present invention (used in the present invention), the head-rotation-member coupling portion of the cleaning head is not particularly limited as long as it has a head rotation axis extending in a direction parallel to the plane direction of the cleaning head and can rotatably couple the cleaning head and the head rotation member.

A preferred configuration of the head rotating member will be described later, but examples of the head rotating member coupling portion include: the first joint member is constituted by (i) a bracket hole (for example, a bracket hole shown in the first embodiment) having an opening portion and configured to be capable of rotatably coupling a rod-shaped bracket as a head rotating member, and (ii) a head-side joint portion (for example, a cylindrical head-side joint portion configured to be insertable into a rotary-member-side joint portion having an arc shape, for example, a first joint member 5a disclosed in japanese patent laid-open No. 2017-384) configured to be capable of rotatably coupling a rotary-member-side joint portion (for example, an arc-shaped rotary-member-side joint portion) as a head rotating member.

When the head-rotating member coupling portion is a bracket hole, the opening of the bracket hole may be disposed at any position of the cleaning head, and is preferably disposed on the side surface portion. In the case where the cleaning head has a longitudinal direction and a width direction, the opening of the holder hole may be disposed on side surface portions (both side surface portions) constituting ends (both end portions) in the longitudinal direction and side surface portions (both side surface portions) constituting ends (both end portions) in the width direction, preferably on side surface portions (both side surface portions) constituting ends (both end portions) in the longitudinal direction. This is from the viewpoint of the convenience of use of the cleaning tool.

In the cleaning tool (used in the present invention), it is preferable that the head rotation axis, the head rotation member (for example, a hole for a holder, a head side joint portion, or the like) of the cleaning head be disposed at the center of the side surface portion in the predetermined direction in the plane direction, the predetermined direction may be the longitudinal direction or the width direction in the case where the cleaning head has the longitudinal direction and the width direction, and the head rotation axis, the head rotation member (for example, a hole for a holder, a head side joint portion, or the like) of the cleaning head be disposed at the center of the longitudinal direction or the center of the width direction. This is from the viewpoint of ease of rotation of the cleaning head and ease of use of the cleaning tool.

The weight may be disposed at any position of the first head region, but is preferably disposed at least at a position distant from the head rotation axis. Since the center of gravity of the cleaning head can be effectively kept away from the head rotation axis (the cleaning head can be easily erected) while suppressing an increase in the mass of the cleaning head, the cleaning head is excellent in vertical cleanability, vertical narrow space cleanability, cleaning surface switchability, and the like.

The weight may be disposed to extend in a direction parallel to the head rotation axis, or may be disposed to extend in a direction orthogonal to the head rotation axis.

In the cleaning tool of the present invention (in use), when the cleaning head has an odd number or an even number of the balance weights, the odd number or the even number of the balance weights may be arranged so as to intersect with the virtual plane of the thickness direction center arranged at the thickness direction center of the cleaning head. Thus, when a user picks up the cleaning tool including the cleaning head, the cleaning head is easily erected in a direction parallel to the vertical direction.

In the cleaning tool of the present invention (in use), when the cleaning head has an even number of weights, the even number of weights may be arranged to be symmetrical with respect to the center virtual plane of the thickness direction. Thus, when a user picks up the cleaning tool including the cleaning head, the cleaning head is easily erected in a direction parallel to the vertical direction.

In addition, in the cleaning tool of the present invention (the cleaning head of the present invention, in use), when the cleaning head is provided with the counter weight, the counter weight may be disposed asymmetrically with respect to the virtual plane of the thickness direction center disposed at the thickness direction center of the cleaning head. For example, when the cleaning head includes one weight, the weight may be disposed so as not to intersect the thickness direction center virtual plane. Accordingly, when the user picks up the cleaning tool including the cleaning head, the cleaning head is easily tilted in a direction away from the vertical direction, and therefore, the cleaning tool can be easily switched between the horizontal cleaning mode and the vertical cleaning mode.

In the cleaning tool of the present invention (for use), when the cleaning head is a cleaning head to which the cleaning sheet is attached for cleaning, the cleaning head may be provided with a holding portion configured to hold at least one of an end portion and the other end portion of the cleaning sheet, and may be configured to be capable of taking an expanded form and a closed form. Thus, the end portion of the cleaning sheet sandwiched by the nip portion is less likely to fall off from the nip portion, and the cleaning sheet is less likely to fall off from the cleaning head. The nip portion may nip one of the one end portion and the other end portion of the cleaning sheet, or may nip both of the one end portion and the other end portion of the cleaning sheet.

The clamping unit is not particularly limited as long as it can clamp the cleaning sheet, but preferably includes a first clamping portion and a second clamping portion, and the first clamping portion and the second clamping portion are rotatably coupled by a rotating end having a clamping unit rotating shaft extending in a direction parallel to the predetermined direction (preferably, in a direction parallel to the head rotating shaft, the longitudinal direction, and the like) and are openably and closably coupled by an opening and closing end extending in a direction parallel to the predetermined direction (preferably, in a direction parallel to the head rotating shaft, the longitudinal direction, and the like). Thus, the end portion of the cleaning sheet sandwiched by the nip portion is less likely to fall off from the nip portion, and the cleaning sheet is less likely to fall off from the cleaning head.

The rotation end and the opening/closing end may be disposed at any position of the cleaning head, and for example, in the case where the rotation end (the clamping portion rotation axis) and/or the opening/closing end extends in a direction parallel to the head rotation axis, the rotation end (the clamping portion rotation axis) and/or the opening/closing end may be disposed at an end portion in a direction orthogonal to the head rotation axis, a region adjacent to the head rotation axis, or the like. In the case where the rotation end (the clamping portion rotation axis) and/or the opening/closing end extends in a direction parallel to the longitudinal direction of the cleaning head, the rotation end (the clamping portion rotation axis) and/or the opening/closing end may be disposed at an end in the width direction, a region adjacent to the head rotation axis, or the like.

In the cleaning tool of the present invention (for use), when the cleaning head is divided into the first head region and the second head region, the rotation end and the opening/closing end may be present in the first head region or the second head region, respectively. The above-mentioned rotating end is preferably present in the first head region, and more preferably at an end of the first head region on the opposite side of the second head region. Thus, when the grip portion is closed after the grip portion is opened and the cleaning sheet is fixed to the cleaning head, the cleaning sheet is not easily stretched, and the cleaning sheet is not easily detached from the cleaning head when the cleaning tool is used.

The opening/closing end is preferably present in the second head region, and more preferably present at an end portion of the second head region opposite to the first head region. Thus, the end of the cleaning sheet is not disposed on the cleaning surface, and therefore the cleaning sheet is less likely to fall off from the cleaning head.

In the cleaning tool of the present invention (used in the present invention), when the cleaning head is configured to hold the cleaning sheet, the cleaning head preferably includes a cleaning sheet fixing portion for holding the cleaning sheet. Examples of the cleaning sheet fixing portion include a nip portion (e.g., a nip portion), a slit portion (e.g., the first slit portion 163 and the second slit portion 165 described in the first and second embodiments), and a hook (hook) member of a hook and loop fastener.

In the cleaning tool of the present invention (used in the present invention), when the cleaning head has the cleaning sheet fixing portion for holding the cleaning sheet, the cleaning head may have one or more cleaning sheet fixing portions on the outer surface thereof, and may also have one or more cleaning sheet fixing portions on the inner surface thereof.

As an example of the cleaning head having one or more cleaning sheet fixing portions on an inner surface thereof, there is an example in which the cleaning head has a nip portion, for example, a nip portion having a first nip portion and a second nip portion. The first and second holding portions may include: the cleaning sheet fixing portion may be a portion which is rotatably coupled by a rotating end having a clamping portion rotating shaft extending in a predetermined direction (preferably, a direction parallel to a head rotating shaft, a longitudinal direction, or the like) and is openably and closably coupled by an opening/closing end extending in the predetermined direction (preferably, a direction parallel to the head rotating shaft, the longitudinal direction, or the like), and a portion in which the first inner surface of the first clamping portion or the second inner surface of the second clamping portion includes the cleaning sheet fixing portion.

In addition, the cleaning head may be provided with one or more cleaning sheet fixing portions on an outer surface thereof, and in the case where the cleaning head is provided with a nip portion, for example, a nip portion having a first nip portion and a second nip portion, a first outer surface of the first nip portion and/or a second outer surface of the second nip portion may be provided with the cleaning sheet fixing portions.

In the cleaning tool of the present invention (in use), when the cleaning head has the holding part having the first holding part and the second holding part and the counter weight is disposed in the first head region, it is preferable that the counter weight and the head rotation member connecting part be disposed in one holding part, that is, the first holding part or the second holding part. Therefore, the user is less likely to feel the weight of the counterweight when using the cleaning tool, and the cleaning head is easily erected when picking up the cleaning tool, and therefore, the cleaning tool (cleaning head) is excellent in vertical cleaning performance, vertical narrow space cleaning performance, cleaning surface switching performance, and the like.

In the cleaning tool of the present invention (used in the present invention), when the cleaning head has the holding portion, for example, when the cleaning head has the holding portion having the first holding portion and the second holding portion, as the holding means for holding the closed form of the first holding portion and the second holding portion, means known in the art can be used, and examples thereof include a pair of protrusion for fitting and recess for fitting, a hook and loop fastener tape (a barbed member and a round-hair member), a pair of magnet and ferromagnetic member (for example, iron, cobalt, nickel), a spring clip, a mechanical lock, and the like.

The pair of fitting protrusions and fitting recesses are respectively protruded and recessed in a predetermined direction, preferably a direction constituting a planar direction of the cleaning head (for example, a longitudinal direction or a width direction), more preferably a direction constituting a longitudinal direction of the cleaning head (for example, a longitudinal direction inside or outside), and further preferably a longitudinal direction inside of the cleaning head. This makes it easy to maintain the closed state of the clamp portion.

In the cleaning tool of the present invention (used in the present invention), the cleaning head may be made of various materials, and the outer surface thereof may be made of a soft member, and the inside thereof may be made of a hard member harder than the soft member. This is from the viewpoint of achieving both operability and cleanability.

Examples of the material constituting the soft member include: examples of the material constituting the hard member include ABS resin, polyolefin (e.g., Polyethylene (PE), polypropylene (PP), etc.), polyethylene terephthalate (PET), Polyacetal (POM), Polycarbonate (PC), Polystyrene (PS), Polyamide (PA), polyvinyl chloride (PVC), acrylic resin and composite materials thereof, and metal (e.g., aluminum).

In the cleaning tool of the present invention (for use), the cleaning tool may be provided with a cleaning head, a head rotating member, and a handle for the cleaning tool.

The head rotating member is not particularly limited as long as it can couple the cleaning head and the cleaning tool handle.

In the case where the head rotating member coupling portion of the cleaning head is a bracket hole having an opening, the head rotating member is preferably formed of a rod-shaped member and is configured as a bracket rotatably coupled to the cleaning head via the bracket hole of the cleaning head. From the viewpoint of cleaning performance in a narrow space, the holder is preferably arranged on a holder virtual plane which is a single plane.

The rod-shaped member may be a member having a circular, elliptical, or polygonal cross section, and the holder is preferably a member having a circular cross section at least at the head connecting portion, and preferably a member having a circular cross section as a whole. This is because the cleaning head is rotated about the head rotation axis, and the holder is less likely to damage the surface to be cleaned. Examples of the material of the holder include metals such as magnetic materials (magnetic metals), iron (e.g., galvanized iron); non-magnetic material (non-magnetic metal), for example, stainless steel, aluminum, and the like.

In the cleaning tool of the present invention (in use), when the cleaning tool is provided with a cleaning head fixing mechanism described later and the cleaning head fixing mechanism is a pair of magnets or a pair of magnets and a ferromagnetic member, the holder may be formed of a ferromagnetic member, a nonmagnetic member, or a combination thereof, and may be provided with a magnet.

For example, the cleaning head can be fixed at a desired position by forming the holder from a non-magnetic material (e.g., stainless steel) and disposing a ferromagnetic material or a magnet on a part thereof.

The holder may include, for example, a head coupling portion rotatably coupled to the holder hole, a handle coupling portion coupled to the handle for the cleaning tool, and a separating portion separating the head coupling portion from the handle coupling portion. The stem connecting portion and the separating portion and the head connecting portion and the separating portion may be connected to each other in a crossing manner or may be integrally bent.

The head coupling portion and the shank coupling portion may have any length. For example, the head coupling portion may have substantially the same length as the handle coupling portion, so that the holder and the cleaning tool are lightweight, and the force applied to the handle of the cleaning tool is easily and reliably transmitted to the cleaning head. Further, the head connecting portion may be longer than the handle connecting portion, so that the force applied to the cleaning tool handle can be more easily transmitted to the cleaning head. Further, the head coupling portion may have a length substantially equal to or longer than the cleaning head, so that the force applied to the cleaning tool handle can be easily transmitted to the entire cleaning head.

Among the head coupling portion, the handle coupling portion, and the separating portion, at least the head coupling portion and the handle coupling portion are preferably disposed on the virtual surface of the stent, and more preferably, the head coupling portion, the handle coupling portion, and the separating portion are disposed on the virtual surface of the stent. This is from the viewpoint of cleanability of a narrow space.

When the head-rotating-member coupling portion of the cleaning head is a head-side joint portion, the head rotating member may be a rotating-member-side joint portion (e.g., a rotating-member-side joint portion configured to cover a cylindrical head-side joint portion) that is configured to be rotatably coupled to a head-side joint portion (e.g., a cylindrical head-side joint portion provided with a head rotating shaft) of the cleaning head.

In the cleaning tool of the present invention (used in the present invention), the cleaning tool is configured so that the cleaning head can be fixed to the head rotating member or the cleaning tool handle (hereinafter, the cleaning tool may be referred to as a cleaning tool having "cleaning head fixing mechanism"). Thus, when the cleaning head is not intended to be rotated, for example, when the cleaning tool is moved or stored, the cleaning head can be fixed in advance, and the cleaning tool has excellent cleaning head fixing properties.

In the cleaning tool of the present invention (used in the present invention), the head rotating member may be a bracket or a rotating member-side joint portion, and is preferably a bracket, in a case where the cleaning head is fixed to the head rotating member. In the case where the head rotating member for fixing the cleaning head is a holder, when the holder is disposed on a holder virtual surface, the cleaning tool is preferably configured such that: the cleaning head and the holder can be fixed so that the plane direction of the cleaning head coincides with the virtual plane of the holder. This makes the cleaning head of the cleaning tool excellent in fixability, particularly in the form of cleaning in a narrow space.

The cleaning head may be fixed to any one of the head coupling portion, the handle coupling portion, or the separating portion of the holder.

Examples of the cleaning head fixing mechanism include a pair of magnets, a pair of magnets and a ferromagnetic material (e.g., iron, cobalt, nickel), a pair of fitting portions, and the like. As an example of the cleaning head fixing mechanism being a pair of magnets, there is an embodiment (for example, the first embodiment) including a magnet disposed on a head rotating member (for example, a head coupling portion, a handle coupling portion, and/or a separating portion of a holder, a rotating member-side joint portion, and the like) and a magnet disposed at a position of the cleaning head corresponding to the magnet disposed on the head rotating member. The same applies to the case where the cleaning head fixing mechanism is a pair of a magnet and a ferromagnetic member. As an example of the cleaning head fixing mechanism being a pair of fitting portions, there can be mentioned a second embodiment described later, that is, a rod-shaped holder as a head rotating member and a groove portion disposed on the cleaning head and formed to fit into the rod-shaped holder.

In the case where the cleaning head fixing mechanism is a pair of magnets, when the magnets are disposed on the head coupling portion of the holder, the head coupling portion of the holder is preferably made of a non-magnetic material, and the magnets are disposed at predetermined positions in the circumferential direction of the head rotation axis, and more preferably, the magnets protrude in a direction orthogonal to the head rotation axis than the head coupling portion of the holder. By this, it is easy to fix the cleaning head at a desired position.

In the cleaning tool of the present invention (in use), when the cleaning head is fixed to the handle for cleaning tool, it is preferable that the head rotation member and the head rotation member connecting portion are a pair of a rotation member side joint portion and a head side joint portion. Further, the cleaning head preferably includes a receiving portion extending in a direction intersecting with (preferably orthogonal to) the head rotation axis in the plane direction and receiving the cleaning tool handle. This is to fix the cleaning head to the handle for the cleaning tool.

The receiving portion may or may not penetrate through the thickness direction of the cleaning head.

As the cleaning head fixing mechanism, as in the case of fixing the cleaning head to the head rotating member, a pair of magnets and a ferromagnetic material (for example, iron, cobalt, nickel), a pair of fitting portions, and the like can be given. As an example of the cleaning head fixing mechanism being a pair of magnets, there is an embodiment including a magnet disposed on the cleaning tool handle and a magnet disposed in the receiving portion of the cleaning head at a position corresponding to the magnet disposed on the cleaning tool handle. The same applies to the case where the cleaning head fixing mechanism is a pair of a magnet and a ferromagnetic member. Examples of the cleaning head fixing mechanism as a pair of fitting portions include a cleaning tool handle and a groove portion disposed in the receiving portion of the cleaning head and formed to fit the cleaning tool handle.

Fig. 12 is a diagram for explaining a cleaning tool 1 according to another embodiment of the present invention (hereinafter, may be referred to as "second embodiment").

In the cleaning tool 1 according to the second embodiment, the cleaning head 3 has groove portions 191 extending in parallel to the width direction S for holding the separating portion 205 of the holder 5 as the head rotation member on both sides in the width direction S of the holder hole 117, which have the side surface of the holder hole 117 as the head rotation member coupling portion.

The holder 5 is formed of a rod-shaped member, and includes a head connecting portion (not shown) rotatably connected to the holder hole 117, a handle connecting portion 203 connected to a cleaning tool handle (not shown), and a separating portion 205 separating the head connecting portion (not shown) from the handle connecting portion 203, and the head connecting portion (not shown), the handle connecting portion 203, and the separating portion 205 are disposed on a holder virtual surface (not shown) which is a single plane.

In the cleaning tool 1 according to the second embodiment, when the planar direction P of the cleaning head 3 is aligned with the holder virtual surface (not shown), the separating portion 205 of the holder 5 is held by the groove portion 191, and thus can be fixed in a state where the planar direction P of the cleaning head 3 is aligned with the holder virtual surface (not shown).

In the cleaning tool of the present invention (used in the present invention), the cleaning tool may further include a rotation suppressing member for suppressing free rotation of the cleaning head about the head rotation axis. Thus, when the cleaning tool is picked up, the cleaning head can be prevented from continuously swinging like a pendulum with the head rotation shaft as an axis.

The rotation suppressing member may be a friction enhancing agent (e.g., grease) disposed between the head rotating member coupling portion and the head rotating member of the cleaning head [ e.g., between the inner surface of the hole for the holder and the outer surface of the holder (e.g., the head coupling portion), between the head-side joint portion and the rotating member-side joint portion, etc. ]. By using the friction enhancer, the spin suppression effect is not easily reduced with the passage of time.

The rotation suppressing member may include a protruding member (e.g., an O-ring disposed on the entire outer periphery of the head coupling portion of the holder) disposed on the head rotating member (e.g., a part or the entire outer periphery of the head coupling portion of the holder, a rotating member-side joint portion, etc.) and configured to be capable of generating friction with the head rotating member coupling portion (e.g., an inner surface of the hole for the holder, a head-side joint portion, etc.), and a protruding member disposed on the head rotating member coupling portion (e.g., an inner surface of the hole for the holder, a head-side joint portion, etc.) and configured to be capable of generating friction with the head rotating member (e.g., an outer surface of the head coupling portion of the holder.

In the cleaning tool of the present invention (use of the present invention), the cleaning tool may be a so-called one-hand grip type, for example, a cleaning tool in which the cleaning head is coupled to the holder as the head rotary member only at one position via the hole for the holder as the head rotary member coupling portion, a cleaning tool in which the cleaning head is coupled to the rotary member-side joint portion as the head rotary member only at one position via the head-side joint portion as the head rotary member coupling portion, or the like.

In the cleaning tool of the present invention (use of the present invention), the cleaning tool may be a so-called two-hand grip type, for example, a cleaning tool in which a cleaning head is coupled to a holder as a head rotary member via a hole for the holder as a head rotary member coupling portion at a plurality of positions (preferably two positions), a cleaning tool in which a cleaning head is coupled to a rotary member-side joint portion as a rotary member via a head-side joint portion as a head rotary member coupling portion at a plurality of positions (preferably two positions), or the like.

By forming the cleaning tool as a one-hand grasping type, as shown in fig. 11, it is easy to clean a narrow space using an end portion of the cleaning head on the side where the holder as the head rotating member does not exist. Further, the cleaning tool is formed to be of a two-hand grasping type, so that the force of the user can be easily transmitted to the cleaning head.

As an example of the two-hand grasping type cleaning tool, there is a cleaning tool in which a holder as a head rotating member is coupled to a cleaning head through two holes for holders disposed at two positions on a side surface portion of the cleaning head.

In the case where the cleaning tool (used in the present invention) has a longitudinal direction and a width direction, the two holes for the holder may be two side portions disposed at both ends in the longitudinal direction of the cleaning head and opposite to each other or two side portions disposed at both ends in the width direction of the cleaning head and opposite to each other, and preferably two side portions disposed at both ends in the longitudinal direction of the cleaning head and opposite to each other.

The two bracket holes may be connected to each other to be integrated with each other or separated from each other, but preferably have one head rotation axis.
