PORTABLE DRIVING IMPLEMENT
PROBLEM TO BE SOLVED: To provide a portable driving implement, which may certainly prevent suction of clothes onto a safety guard, and in which projection level of from one side part to a side of a fan case may be reduced, thereby, a required blowing efficiency may be realized without enlargement, increment in weight and worsening in workability.SOLUTION: A suction port 25 for suction is arranged on one side part 20L of a fan case 20 of an air blower 15 and a safety guard 30 is arranged on the suction port 25. In addition, a seal prevention guard 40 is provided on one side part 20L of the fan case 20, which comprises a surface part 41 on which a top surface opening 45 facing the suction port 25 is arranged and 3 leg parts 42A, 42B, 42C for making the top surface opening 45 to face the suction port 25 with a predetermined distance and a grid 43 is arranged on the top surface opening 45. In addition, an average opening area of each opening part of the grid 43 arranged on the top surface opening 45 of the seal prevention guard 40 is lager than an average opening area of each opening part of grid 33 of the safety guard 30.SELECTED DRAWING: Figure 2
【課題】安全ガードへの衣服の吸い付きを確実に阻止できるとともに、ファンケースの一側面部からの側方への張り出し量を小さくし得、もって、大型化、重量増加、作業性の悪化等を招くことなく、所要の送風性能が得られるようにされた携帯型動力作業機を提供する。【解決手段】送風機１５におけるファンケース２０の一側面部２０Ｌに吸気用の吸入口２５が設けられるとともに、該吸入口２５に安全ガード３０が設けられる。また、ファンケース２０の一側面部２０Ｌに、吸入口２５に対向する天面開口４５が設けられた天面部４１と、天面開口４５を吸入口２５から所定距離をあけて対面させるための３本の脚部４２Ａ、４２Ｂ、４２Ｃとを持ち、天面開口４５に格子４３が設けられた閉塞防止ガード４０が付設される。そして、閉塞防止ガード４０における天面開口４５に設けられた格子４３の各目部分の平均開口面積を安全ガード３０における格子３３の各目部分の平均開口面積より大きくする。【選択図】図２
