As shown in FIGS. 2 and 4, the short-side concave portion 122 is concave toward the upper side formed in the vicinity of both ends in the short-side direction (X-axis direction) on the lower surface side of the bottom surface portion 12. It is a formed part. As a result, when the cleaning tool 100 is used, the vicinity of both ends in the short side direction (X-axis direction) on the lower surface side of the head portion 1 is not in close contact with the floor surface, and a gap is formed between the floor surface. Become.

短手方向凹状部122は、ヘッド部1の短手方向(X軸方向)の両端部付近の下面側において、床面との間に間隙を生じさせることが可能であれば任意の形状に形成することが可能であるが、ヘッド部1の前側又は後側の端部のY軸方向中央部において底面部12の下面側が最も大きく凹むように形成され、当該部分から離れるにつれて凹みが小さくなり、平面部121になだらかに接続されるように形成されていることが望ましい。
短手方向凹状部122は、最も凹んだ部分において、上方に0.1mm〜5mm、より好ましくは0.5mm〜3mm平面部121と比較して凹むように形成される。
The short-side concave portion 122 is formed in any shape as long as a gap can be formed between the head portion 1 and the floor surface on the lower surface side in the vicinity of both ends in the short-side direction (X-axis direction). Although it is possible to do so, the lower surface side of the bottom surface portion 12 is formed to be the most recessed at the Y-axis direction central portion of the front or rear end of the head portion 1, and the dent becomes smaller as the distance from the portion decreases. It is desirable that it be formed so as to be gently connected to the flat portion 121.
The short-side concave portion 122 is formed so as to be recessed upward in the most concave portion in comparison with the plane portion 121 of 0.1 mm to 5 mm, more preferably 0.5 mm to 3 mm.

底面部12の下面側に短手方向凹状部122が形成されていることによって、掃除具100をヘッド部1の短手方向(X軸方向)に動かして床面の清掃を行う際に、床面のごみがヘッド部1の前後の端部に溜まらずに、ヘッド部1の下面に誘い込まれるようになり、ごみの捕集性を向上させることができる。   Since the concave portion 122 in the short-side direction is formed on the lower surface side of the bottom surface portion 12, the floor surface is cleaned when the cleaning tool 100 is moved in the short-side direction (X-axis direction) of the head portion 1. The dust on the surface does not collect at the front and rear end portions of the head portion 1, but is attracted to the lower surface of the head portion 1, thereby improving the collection property of the dust.

(長手方向凹状部)
長手方向凹状部123は、図3及び図4に示すように、底面部12の下面側の長手方向(Y軸方向)の両端部付近に形成された上方に向けて凹状となるように形成された部分である。これによって、掃除具100の使用時において、ヘッド部1の下面側の長手方向(Y軸方向)の両端部付近は、床面に密着せず、床面との間に間隙が生じることとなる。
(Longitudinal concave part)
As shown in FIGS. 3 and 4, the longitudinal concave portion 123 is formed so as to be concave toward the upper side formed in the vicinity of both ends in the longitudinal direction (Y-axis direction) on the lower surface side of the bottom surface portion 12. Part. Thus, when the cleaning tool 100 is used, the vicinity of both ends in the longitudinal direction (Y-axis direction) on the lower surface side of the head portion 1 does not adhere to the floor surface, and a gap is generated between the floor surface. .

長手方向凹状部123は、ヘッド部1の長手方向(Y軸方向)の両端部付近の下面側において、床面との間に間隙を生じさせることが可能であれば任意の形状に形成することが可能であるが、ヘッド部1の右側又は左側の端部のX軸方向中央部において底面部12の下面側が最も大きく凹むように形成され、当該部分から離れるにつれて凹みが小さくなり、平面部121になだらかに接続されるように形成されていることが望ましい。
長手方向凹状部123は、最も凹んだ部分において、上方に0.1mm〜5mm、より好ましくは0.5mm〜3mm平面部121と比較して凹むように形成される。
The longitudinal concave portion 123 is formed in an arbitrary shape as long as a gap can be generated between the head portion 1 and the floor surface on the lower surface side in the vicinity of both end portions in the longitudinal direction (Y-axis direction). However, the lower surface side of the bottom surface portion 12 is formed so as to be recessed most greatly in the X-axis direction central portion of the right or left end portion of the head portion 1, and the recess becomes smaller as the distance from the portion decreases, and the flat surface portion 121. It is desirable that it is formed so as to be connected smoothly.
The longitudinal concave portion 123 is formed so as to be recessed upward in the most concave portion by 0.1 mm to 5 mm, and more preferably 0.5 mm to 3 mm.

底面部12の下面側に長手方向凹状部123が形成されていることによって、掃除具100をヘッド部1の長手方向(Y軸方向)に動かして床面の清掃を行う際に、床面のごみがヘッド部1の左右の端部に溜まらずに、ヘッド部1の下面に誘い込まれるようになり、ごみの捕集性を向上させることができる。   Since the longitudinal concave portion 123 is formed on the lower surface side of the bottom surface portion 12, when the cleaning tool 100 is moved in the longitudinal direction (Y-axis direction) of the head portion 1 to clean the floor surface, The dust is not collected at the left and right end portions of the head portion 1 but is attracted to the lower surface of the head portion 1, so that the collection property of the dust can be improved.
