Description

また、下ケースの底部の上面に、前後方向に延びるように立設されて電動送風機ケースを載置する第１の下ケース底部リブを設け、第１の下ケース底部リブの後方に上方に向かって延設する段差部とこの段差部の上端に連なって上方後方に傾斜する傾斜部を形成し、電動送風機ケースの後端の下部の角部が前記段差部と当接するようにしたので、電動送風機ケースを下ケースに固定する際、電動送風機ケースの後側の下端が傾斜部を滑って段差部にガイドされるので、組立性が向上する。 In addition, a first lower case bottom rib is provided on the upper surface of the bottom of the lower case so as to extend in the front-rear direction and on which the electric blower case is placed. The first lower case bottom rib is directed upward behind the first lower case bottom rib. A step part extending and an inclined part that slopes upward and rearward from the upper end of the step part are formed, and the lower corner of the rear end of the electric blower case is in contact with the step part. When fixing the blower case to the lower case, the lower end of the rear side of the electric blower case slides on the inclined portion and is guided by the stepped portion, so that the assemblability is improved.

また、コード巻き取り部は、両側に電源コードの巻き取りをガイドする側円板が設けられ、下ケースの底部の上面で側円板の近傍に、少なくとも一方の側円板に沿って近接した第２の下ケース底部リブが形成されると共に、底カバーの底部の上面に、第２の下ケース底部リブと連なるように側円板に沿って近接した第３の底カバーリブを設けたので、電源コードが緩んでしまった場合でも、コード巻き取り部から電源コードが飛び出して外れることがなく、電源コードの巻き取りを確実にガイドできる。
Further, the cord winding part is provided with side disks for guiding the winding of the power cord on both sides, and is close to the side disk on the upper surface of the bottom of the lower case along at least one side disk. Since the second bottom case bottom rib is formed, and the top surface of the bottom of the bottom cover is provided with the third bottom cover rib adjacent to the second bottom case bottom rib so as to be continuous with the second bottom case rib. Even when the power cord has become loose, the power cord does not jump out of the cord winding portion and comes off, so that the winding of the power cord can be reliably guided.
