In particular, since the convex rib portion 18d has a substantially vertical surface portion 18e on the drum opening 10b side, it is possible to strongly prevent the small laundry 19 from entering.

そして、小物洗濯物１９の一部が、可動部である回転ドラム１０に接触していると、回転ドラム１０の回転時に、回転ドラム１０側に引き込まれ、パッキン部材１８から回転ドラム１０側に移動する作用効果を得ることができる。 When a part of the small laundry 19 is in contact with the rotating drum 10 which is a movable portion, it is pulled toward the rotating drum 10 side when the rotating drum 10 rotates, and moves from the packing member 18 to the rotating drum 10 side. It is possible to obtain the effect of the action.

なお、本実施の形態１においては、凸リブ部１８ｄは、回転ドラム１０のドラム開口部１０ｂから、寸法ｈ（例えば、１０ｍｍ）程度離間して設けているが、パッキン部材１８の回転ドラム１０のドラム開口部１０ｂから最も近い位置に設けても、上記と同等の作用効果を得ることができる。 In the first embodiment, the convex rib portion 18d is provided at a distance of about h (for example, 10 mm) from the drum opening 10b of the rotary drum 10, but the rotary drum 10 of the packing member 18 is provided. Even if it is provided at the position closest to the drum opening 10b, the same effect as described above can be obtained.

以上のように、本実施の形態においては、前面板開口部１７ａと水槽開口部９ａとの間に連結されたゴムなどの弾性材からなる環状筒状のパッキン部材１８は、前面板開口部１７ａから後方へ延びる略円筒部１８ｂと、略円筒部１８ｂの前端部の内周に形成され、蓋体１６を閉めた時に内蓋１６ａに当接して水密的にシールするリップ部１８ａと、略円筒部１８ｂ後端近傍から前方かつ外方へ折り返すことにより外周側に膨出し水槽開口部９ａと連結する可撓性の膨出部１８ｃとを設けるとともに、略円筒部１８ｂの内周側でドラム開口部１０ｂ側に断面略三角形状の凸リブ部１８ｄを形成する構成としている。 As described above, in the present embodiment, the annular tubular packing member 18 made of an elastic material such as rubber connected between the front plate opening 17a and the water tank opening 9a is the front plate opening 17a. A substantially cylindrical portion 18b extending rearward from the surface, a lip portion 18a formed on the inner circumference of the front end portion of the substantially cylindrical portion 18b, and a lip portion 18a that abuts on the inner lid 16a and watertightly seals when the lid 16 is closed, and a substantially cylindrical portion. A flexible bulging portion 18c that connects to the bulging water tank opening 9a is provided on the outer peripheral side by folding forward and outward from the vicinity of the rear end of the portion 18b, and a drum opening is provided on the inner peripheral side of the substantially cylindrical portion 18b. A convex rib portion 18d having a substantially triangular cross section is formed on the portion 10b side.
