As a result, it is difficult to cover a wide range. Effective use of the entire area of the surface of the cleaning sheet. Further, in the above-described Patent Documents 1 to 5, the shape of the bottom surface of the cleaning head is such that the central portion protrudes most from the surface to be cleaned, and the bottom surface is separated from the surface to be cleaned at the front and rear. Therefore, when the grip head is moved by hand and the cleaning head plate is moved forward, the cleaning head tends to be inclined toward the front, and the cleaning head is pressed against the surface to be cleaned such as the floor in an unstable posture, and the grip is pushed. The force of the shank cannot be effectively transmitted to the cleaning head, and when the cleaning head is slid along the surface to be cleaned, the resistance acting on the handle is increased. The present invention has been made to solve the above problems, and an object thereof is to provide a wide range of surfaces for cleaning sheets laid on the bottom of a cleaning head for effectively capturing garbage or dust, and for cleaning, cleaning heads and A sweeping device such as a floor that is easily stabilized by the contact state of the cleaning surface. [Technical Solution to Problem] The first invention of the present invention is directed to a cleaning tool including a cleaning head and a grip portion connected to an upper portion of the cleaning head, and a cleaning sheet is laid on the bottom of the cleaning head.

And a rear concave portion extending from the rear edge portion toward the front to the middle of the front edge portion; and the center line extending in the longitudinal direction of the front concave portion does not coincide with the center line extending in the longitudinal direction of the rear concave portion. In the cleaning device according to the second aspect of the present invention, since the front concave portion and the rear concave portion are arranged to be displaced in the lateral direction, the front concave portion is formed in the front concave portion. In the portion of the rear concave portion, the garbage or the dust can be concentrated on the surface of the cleaning sheet, and as a result, the large area in the lateral direction of the cleaning surface of the cleaning sheet can be effectively used. In the second invention of the present invention, the front side can be made At least one of the recessed portion and the rear recessed portion is formed in plural at intervals in the lateral direction. However, one of the front recessed portion and the rear recessed portion may be provided, and a plurality of the front recessed portion and the rear recessed portion may be formed separately. According to the first invention and the second aspect of the present invention, at least a part of the cleaning head other than the recessed portion can be in contact with the same plane. Since the region other than the recess can be blocked by the same plane, When the cleaning head slides along the surface to be cleaned such as the floor, the posture of the cleaning head is easy to stabilize. In particular, the cleaning head is preferably located in the outer side of the lateral direction with the concave portion interposed therebetween, so as to be able to be blocked in the same plane. • 8-(6) (6) 1299259 and 'the above-described recess of the present invention is slow as it gradually faces toward the center in the longitudinal direction of the bottom. The slower and shallower terrain is ideal. Further, it is preferable that the recessed portion is gradually shallowed toward both sides in the lateral direction toward the bottom. The concave portion 'is a shape that gradually becomes shallow toward the center portion or the lateral direction'. The dust or the garbage on the surface to be cleaned by the concave portion is easily guided to the peripheral portion of the concave portion, and can be effectively cleaned using a wide range of cleaning sheets. [Effect of the Invention] In the present invention, it can be laid on the bottom of the cleaning head. The wide range of the surface of the sheet to be cleaned effectively captures garbage or dust falling on the surface to be cleaned such as the floor. Further, the posture of the cleaning head can be stably slid on the surface to be cleaned.

As a result, the front concave portion 30 and the rear concave portion 40 are in the lateral direction. Configure interactively. The center line Of of the front recess 30 is an intermediate point between the center line 〇r and the center line Ο r of the concave portion 40 adjacent to each other, and the center line Or of the rear recess 40 is located at the center of the recess 30 adjacent to each other. The middle point between the lines Of and If. Further, the distance between the center line Of the front concave portion 30 and the center line Or of the rear concave portion 40 in the lateral direction is the same as the above-described wide size W1. The front side region (A) from the right end edge portion 26 toward the inner side within the wide dimension W2, and the side surface region (A) from the left end edge portion 27 toward the inner side from the wide dimension W2 are not formed with the front recessed portion 30 and Rear recess 40. The longitudinal dimension L1 of the front recessed portion 30 and the longitudinal dimension L1 of the rear recessed portion 40 are smaller than 1/2 of the longitudinal dimension L0 of the bottom portion 23, and the front recessed portion 30 and the rear recessed portion 40 are disposed at a gap L2 in the longitudinal direction. The longitudinal dimension L2 is smaller than the longitudinal dimension L1 described above. Further, in the embodiment of Fig. 4, the pitch L2 may be zero. The bottom portion 23 is an almost full area of a region other than the front recessed portion 30 and the rear recessed portion 40, that is, the side surface region (A) (A), the outer side portion (B) of the front recess portion 30, and the rear recess portion 40. The outer region (C) and the strip-shaped region (D) having a longitudinal dimension L2 and extending in the lateral direction can be blocked in the same plane. That is, these areas (A) (B) (C) (D) are concave and convex surfaces that can be blocked on a plane or the same plane. In the embodiment of Fig. 4, each of the above regions (A) (B) (C) -12-(10) (10) 1299259 (D) has a concavo-convex shape in which a plurality of mutually intersecting trenches are formed. Therefore, the front edge portion 24 of the bottom portion 23 is substantially parallel to the same plane except for the front recess portion 30, and the trailing edge portion 25 is also substantially parallel to the same plane except for the rear recess portion 40. Further, by forming each of the above regions (A) (B) (C) (D) into a concavo-convex shape, the anti-slip function between the bottom portion 2 3 and the cleaning sheet 50 can be exhibited. Each of the front recesses 30 has a bottom inclined surface 3!, and side inclined surfaces 3 2, 3 2 on the both sides. As shown in Fig. 5, the bottom inclined surface 31 is a plane or a curved surface which gradually approaches the cleaning surface 60 (see Fig. 6) from the front edge portion 24 toward the rear edge portion 25. Therefore, the depth from the surface of the bottom portion 23 to the bottom inclined surface 31 is the deepest at the leading edge portion 24, and becomes shallower toward the rear. As shown in Fig. 3, the side inclined surfaces 3 2, 3 2 ' are a plane or a curved surface that gradually approaches the surface to be cleaned 60 as it goes from the bottom inclined surface 31 toward the outside in the lateral direction. As shown in Fig. 4, the bottom inclined surface 31 and the boundary lines 3 3 and 3 3 of the inclined surfaces 3 2 and 3 2 on both sides are linearly expanded toward the rear side in the lateral direction. shape. However, the above-mentioned boundary lines 3 3 and 3 3 may be curved, and the interval in the lateral direction is gradually widened as approaching the rear. The shape of the rear recessed portion 40 is a shape symmetrical with respect to the front recessed portion 3'. The front recessed portion 30 and the rear recessed portion 40 are oriented in the reverse direction, and have the same shape or size. The rear recessed portion 40 also has a bottom inclined surface 41 and side inclined surfaces 42, 42 on the both sides, and a boundary line 4 3 ' 4 3 between the bottom inclined surface 4 and the side inclined surfaces 4 2, 4 2 The interval between the lateral directions is a shape that gradually expands toward the front. -13- (11) (11) 1299259 The depth dimension d of the front recessed portion 30 and the depth dimension d of the rear recessed portion 40 of the trailing edge portion 25 are the same as the thickness of the cleaning sheet 5 Or slightly larger, the depth dimension d is, for example, about 1 to 5 mm. In the cleaning head u of the embodiment, the depth dimension d is 2 mm. The cleaning head 1 of the embodiment shown in the drawing has the same depth dimension d of the front recessed portion 3 〇 and the rear recessed portion 40. However, the depth dimension d of the front recessed portion 30 and the rear recessed portion 40 may be different from each other, or the depth dimension d of the front recessed portion 30 may be different from each other, or the depth dimension of the rear recessed portion 40 may be different from each other. The cleaning sheet 50 is formed of a non-woven fabric or a laminated body of a plurality of non-woven fabrics. Or a fiber density is disposed on a cleaning side surface of a base sheet formed of a non-woven fabric or the like, or a long fiber bundle is joined, or a cleaning side surface of the base material sheet, such as a gas flow (thr 〇 ugh - air) non-woven fabric, or the like The lower non-woven. Alternatively, the cleaning side surface of the cleaning sheet 50 formed of the non-woven fabric is used to form a nonwoven fabric. Next, a description will be given of a method of using the above-described cleaning tool. As shown in Figs. 1 and 6, the cleaning head 11 is provided with a cleaning sheet 50 which can be discarded. The cleaning sheet 50 is laid on the bottom portion 23 of the cushion 22, and is rolled over the upper surface of the fixing plate 21, and is pressed into the slit 16a of the sheet fixing means 15 provided on the upper surface of the fixing plate 21. . The cleaning head plate 11 on which the cleaning sheet 50 is mounted has a longitudinal direction of -14 - (12) (12) 1229959 (Y direction) which is mainly slid toward the front and rear direction and on the surface to be cleaned 60. At this time, the interposer shaft portion 13 applies the pressing force to the cleaning head 11, and the cleaning sheet 50 is pressed against the surface to be cleaned 60 by the bottom portion 23 of the cushion 22. In front of the bottom portion 23 of the cushion 22, since the front concave portion 30 and the outer region (Β) are alternately arranged in the lateral direction, the cleaning sheet 5 is strongly pressurized at the outer region (Β) and the sheet density is changed. High, at the front recess 30, the pressing force is alleviated and the sheet density is lowered. In the front concave portion 30, since the bottom inclined surface 3 is formed, the pressing force applied to the cleaning sheet 50 is gradually increased toward the rear in the lower portion of the front concave portion 30. Further, since the side inclined surface 32 is formed, the pressing force applied to the cleaning sheet 50 in the lower portion of the front concave portion 30 gradually increases toward the outer region (Β). Therefore, in the lower portion of the front recessed portion 30, garbage or dust is guided to the rear side and the side surface, and in a wide area of the lower portion of the front recessed portion 30, garbage or dust is easily and uniformly attached to the cleaning sheet 50. Furthermore, a lot of garbage or dust will be concentrated in the rear part and the two side parts of the front recess. Further, by the bottom inclined surface 3 1, garbage or dust is easily guided to the vicinity of the strip-shaped region (D) located behind the front recess 30, and since the side inclined surfaces 3 2, 3 2 are formed, garbage or dust is formed. It is easy to be guided to the outer side (Β) on both sides of the front recess 30. In this way, in the portion of the front recessed portion 30, garbage or dust is easily concentrated immediately below the recessed portion and in the portion of the recessed portion of the recessed portion. On the other hand, in the outer region (Β), garbage or dust tends to concentrate in the vicinity of the leading edge portion 24, and as a result, the sweeping surface of the cleaning sheet •15-(13) (13) 1299259 50 can capture garbage in a wide range. Or dust. This is also the same for the rear recess 40 and the outer region (C) on both sides. Further, since the front concave portion 30 and the rear concave portion 40 are alternately arranged in the lateral direction, when the cleaning head 移动 is moved forward, the garbage collected by the cleaning surface of the cleaning sheet 50 is located below the front concave portion 30. Even if the dust moves toward the rear, the garbage or dust can be caught in the outer side region (C). Similarly, when the cleaning head 1 1 is moved rearward, the garbage or dust collected on the cleaning surface of the cleaning sheet 50 can be moved forward even if the garbage or the dust collected on the cleaning surface of the cleaning sheet 50 is moved forward. The outer area (Β) is captured. By the mutual arrangement of the front concave portion 30 and the rear concave portion 40, the cleaning surface of the cleaning sheet 50 can be effectively used for the cleaning operation. Further, the left and right side surface regions (A), the outer side regions (B) (C), and the strip-shaped region (D) are slidable to the same plane, and are blocked at the front edge portion 24 and the portion other than the front recess portion 30. In the surface to be cleaned 60, the portion other than the rear recess portion 40 and the rear recess portion 40 are also in contact with the surface to be cleaned 60. Therefore, when the state in which the cleaning head plate 1 1 and the surface to be cleaned 60 are in contact with each other is stabilized, and the sliding head 11 is slid forward, the cleaning head 11 is less likely to be reversed. Since the cleaning head 1 1 is in a stable state in contact with the surface to be cleaned 60, even if the width of the cleaning head plate 1 is enlarged, it is easy to use as a large cleaning tool. Further, the present invention is not limited to the above embodiment. For example, in order to clean the bottom portion 2 3 of the head plate 1 1 , a plurality of front recesses 30 may be provided, for example, two, and the rear recess 40 is only set with -16-(14) (14) 1299259 1 In contrast, a plurality of rear recesses 40 may be provided, and only one of the front recesses 30 is provided. Further, one of the front recessed portion 30 and the rear recessed portion 40 may be provided, and one of the front recessed portion 30 and the one of the rear recessed portions 40 may be arranged to be displaced in the lateral direction. Alternatively, only a plurality of front recesses 30 may be provided without providing the rear recess 40'. Alternatively, only a plurality of rear recesses 40 may be provided, and the front recess 30 may not be provided. Further, in the embodiment shown in Fig. 4, the widths of the front recessed portion 30 and the rear recessed portion 40 are the same as wi, and the distance between the center line Of of the front recessed portion 30 and the center line Or of the rear recessed portion 40 is W1. Therefore, when the bottom portion 23' is viewed from the lateral direction, except for the entire area other than the side surface area (a) (A), the front recessed portion 30 or the rear recessed portion 40 has a structure in which it must exist. Therefore, it can effectively capture garbage or dust in a wide range. However, the width of the front recess 30 or the rear recess 40 may be shorter than the distance between the center line Of and the center line Of. Alternatively, the width of the front recess 30 or the rear recess 40 may be longer than the distance between the center line Of and the center line Of, and the front recess 30 and the rear recess 40 may be repeated in the front-rear direction. In either embodiment, in the embodiment of the present invention, it is preferable that at least a part of the rear side of the front recessed portion 30 has an outer side region (C)' and at least a portion of the front side of the rear recessed portion 40 has an outer side region (B).
