In such a power tool, it is possible to improve ease of gripping, design, shock absorption, and the like with a soft elastomer while securing rigidity and impact resistance with a hard resin material.
ところで、上記のような被覆部を設ける場合、例えば、溶融状態のエラストマーを成形型内に充填して被覆部をハウジングに一体成形することが考えられるが、ハウジングの形状が複雑な場合等、被覆部のハウジングに対する接着力が局部的に弱くなることがあり、被覆部が局部的に剥がれ易くなる虞がある。 By the way, when providing the covering portion as described above, for example, it is conceivable that the molten elastomer is filled in the mold and the covering portion is integrally formed with the housing. There is a possibility that the adhesive strength of the part to the housing is locally weakened, and the covering part may be easily peeled off locally.
本発明は、上記課題を解決するためになされたものであって、その目的は、被覆部の局部的な剥がれを抑えることができる電動工具を提供することにある。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an electric tool capable of suppressing local peeling of a covering portion.

また、本実施形態の前記分割基端面２１ｂ、前記分割上面２１ｃ、分割下面２１ｄ及び分割把持部後方面２１ｅにおける接合部位側端部には、それぞれ被覆部２２の接着力を強くして剥がれを抑えるためのアンカー溝２１ｆが形成されている。 Moreover, the adhesive force of the coating | coated part 22 is strengthened at the joining part side edge part in the said division | segmentation base end surface 21b, the said division | segmentation upper surface 21c, the division | segmentation lower surface 21d, and the division | segmentation holding part rear surface 21e of this embodiment, respectively, and suppresses peeling. An anchor groove 21f is formed.
次に、上記電動工具１０（整流凸部３１及び整流凹部３２）の作用について説明する。
図４に白抜き矢印で示すように、溶融状態のエラストマーを成形型内の前記一側面２１ａに対応した位置（ゲート位置Ｇ）から充填すると、エラストマーは分割基端面２１ｂ側、分割上面２１ｃ及び分割下面２１ｄのそれぞれに流れる。このとき、分割基端面２１ｂ側に流れる溶融状態のエラストマーは、整流凸部３１及び整流凹部３２の作用によって分割基端面２１ｂにおける接合部位側（本体部１４の幅方向中央に対応した部位側）に流れ易くなる。具体的には、溶融状態のエラストマーは、整流凸部３１によって、分割上面２１ｃ側及び分割下面２１ｄ側に逃げるように流れてしまうことが抑えられるとともに、整流凹部３２によって、分割基端面２１ｂの上下方向の中央部側（前記接合部位側）に引き込まれ易くなる。
Next, the effect | action of the said electric tool 10 (rectifying convex part 31 and the straightening recessed part 32) is demonstrated.
As shown by the white arrow in FIG. 4, when the molten elastomer is filled from a position (gate position G) corresponding to the one side surface 21a in the mold, the elastomer is divided into the divided base end surface 21b, the divided upper surface 21c and the divided upper surface. It flows to each of the lower surface 21d. At this time, the melted elastomer flowing toward the split base end face 21b is moved to the joining part side (part corresponding to the center in the width direction of the main body part 14) on the split base end face 21b by the action of the straightening convex part 31 and the straightening concave part 32. It becomes easy to flow. Specifically, the molten elastomer is prevented from flowing so as to escape to the divided upper surface 21c side and the divided lower surface 21d side by the rectifying convex portion 31, and the upper and lower sides of the divided base end surface 21b by the rectifying concave portion 32. It becomes easy to be drawn in to the central part side (the joining site side) in the direction.
次に、上記実施の形態の特徴的な効果を以下に記載する。
（１）分割基端面２１ｂには、一側面２１ａ側から流れてくる流体を本体部１４の幅方向中央に対応した接合部位側に流し易くするための整流部としての整流凸部３１及び整流凹部３２が形成される。よって、例えば、溶融状態のエラストマーを成形型内の一側面２１ａに対応した位置から充填して被覆部２２を分割ハウジング２１に一体成形する際に、分割基端面２１ｂにおける接合部位側にエラストマーが流れ易くなり、該接合部位側における被覆部２２の接着力を強くすることができる。その結果、分割基端面２１ｂの接合部位側における被覆部２２の剥がれを抑えることができる。
Next, the characteristic effects of the above embodiment will be described below.
(1) The split base end face 21b has a rectifying convex part 31 and a rectifying concave part as a rectifying part for facilitating the flow of the fluid flowing from the side surface 21a side to the joint part side corresponding to the center in the width direction of the main body part 14. 32 is formed. Therefore, for example, when the molten elastomer is filled from a position corresponding to the one side surface 21a in the mold and the covering portion 22 is integrally formed with the divided housing 21, the elastomer flows to the joining portion side of the divided base end surface 21b. It becomes easy and the adhesive force of the coating | coated part 22 in this joining site | part side can be strengthened. As a result, it is possible to suppress peeling of the covering portion 22 on the joining site side of the divided base end face 21b.
（２）本実施形態では整流部として分割基端面２１ｂの上下方向の端部側に凸設された整流凸部３１を含むため、溶融状態のエラストマーが成形型内の一側面２１ａに対応した位置から充填された際に分割基端面２１ｂに流れてきたエラストマーが分割上面２１ｃ側及び分割下面２１ｄ側に逃げるように流れてしまうことを抑えることができる。よって、分割基端面２１ｂにおける接合部位側にエラストマーが流れ易くなり、該接合部位側における被覆部２２の接着力を強くすることができる。 (2) In this embodiment, since the rectifying convex portion 31 is provided as a rectifying portion so as to protrude from the vertical end portion of the split base end surface 21b, the molten elastomer corresponds to the one side surface 21a in the mold. It can be suppressed that the elastomer that has flowed to the split base end face 21b when it is filled from the side flows away to the split upper surface 21c side and the split lower surface 21d side. Therefore, the elastomer easily flows to the joining site side of the divided base end surface 21b, and the adhesive force of the covering portion 22 on the joining site side can be increased.
（３）本実施形態では、整流部として分割基端面２１ｂの上下方向の中央部に凹設された整流凹部３２を含むため、溶融状態のエラストマーが成形型内の一側面２１ａに対応した位置から充填された際に分割基端面２１ｂに流れてきたエラストマーが分割基端面２１ｂの上下方向の中央部側に引き込まれ易くなる。よって、分割基端面２１ｂにおける接合部位側にエラストマーが流れ易くなり、該接合部位側における被覆部２２の接着力を強くすることができる。 (3) In the present embodiment, since the rectifying recess 32 is provided as a rectifying portion in the central portion in the vertical direction of the divided base end surface 21b, the molten elastomer is from a position corresponding to the one side surface 21a in the mold. The elastomer that has flowed to the split base end face 21b when it is filled is easily drawn into the center of the split base end face 21b in the vertical direction. Therefore, the elastomer easily flows to the joining site side of the divided base end surface 21b, and the adhesive force of the covering portion 22 on the joining site side can be increased.
上記実施形態は、以下のように変更してもよい。
・上記実施形態では、分割基端面２１ｂには、整流部としての整流凸部３１及び整流凹部３２が形成されるとしたが、一側面２１ａ側から流れてくる流体を本体部１４の幅方向中央に対応した接合部位側に流し易くするための整流部が形成されれば、他の構成に変更してもよい。例えば、整流凸部３１及び整流凹部３２の内のいずれか一方のみが形成された構成としてもよい。また、上記実施形態の整流凸部３１及び整流凹部３２の形状や数を変更してもよい。
The above embodiment may be modified as follows.
In the above embodiment, the split base end face 21b is formed with the rectifying convex part 31 and the rectifying concave part 32 as the rectifying part. However, the fluid flowing from the side face 21a side is centered in the width direction of the main body part 14. If the rectification | straightening part for making it easy to flow to the junction part side corresponding to is formed, you may change into another structure. For example, only one of the rectifying convex portion 31 and the rectifying concave portion 32 may be formed. Moreover, you may change the shape and number of the straightening convex part 31 and the straightening recessed part 32 of the said embodiment.
・上記実施形態では、被覆部２２は、前記一側面２１ａと前記分割基端面２１ｂと前記分割上面２１ｃと前記分割下面２１ｄと前記分割把持部後方面２１ｅとを連続して（繋がった状態で）覆うように設けられるとしたが、分割把持部後方面２１ｅは連続して覆わない被覆部に変更してもよい。 In the above-described embodiment, the covering portion 22 has the one side surface 21a, the divided base end surface 21b, the divided upper surface 21c, the divided lower surface 21d, and the divided gripping portion rear surface 21e continuously (in a connected state). Although it is provided so as to cover, the divided gripping portion rear surface 21e may be changed to a covering portion that does not cover continuously.
