By inserting a hand into the opening 18 constituting the operation portion 40 of the lever 6, grasping the lower part of the lever 6, pulling the lower part of the lever 6 outward and upward (see FIG. 5), and then lowering the lever 6. The lever engaging convex portion 19 is engaged with the tank engaging convex portion 25, and in a state where the tank engaging convex portion 25 and the lever engaging convex portion 19 are engaged, the lower portion constituting the operating portion 40 of the lever 6 is the washing machine main body 1 By pushing it toward the side, the lever engaging convex portion 19 engages with the tank engaging convex portion 25, and the tank 2 can be locked to the washing machine main body 1 (see FIG. 4).

この状態から、レバー６の操作部４０を構成する開口１８に手を進入させてレバー６の下部をつかみ、レバー６の下部を外方且つ上方へ引き上げると、タンク係合凸部２５に対するレバー係合凸部１９のかみ合いが解除され（図５参照）、さらに、引き上げを続けることにより、タンク突起２６にレバー突起２０が内側からかみ合いタンク２が上方へ押し上げられる（図６参照）。 From this state, when a hand is inserted into the opening 18 constituting the operation portion 40 of the lever 6, the lower portion of the lever 6 is grasped, and the lower portion of the lever 6 is pulled outward and upward, the lever engagement with the tank engaging convex portion 25 is engaged. The meshing of the convex portion 19 is released (see FIG. 5), and by continuing to pull up, the lever protrusion 20 is engaged with the tank protrusion 26 from the inside and the tank 2 is pushed upward (see FIG. 6).

このように、本実施形態によれば、洗浄機本体１の外側に配置され、タンク２のロック又はロック解除の際に操作されるレバー６と、一端１０，１０が洗浄機本体１の外側に第１ピン１１を介して回転可能に連結されると共に、他端２３，２３がレバー６の内側に第２ピン２２を介して回転可能に連結されたアーム７と、タンク２の外側においてタンク２を洗浄機本体１に搭載した際の第１ピン１１より上方位置に設けられ、上方へ突出するタンク係合凸部２５と、レバー６の上部内側に設けられ、レバー６の操作により、タンク係合凸部２５にかみ合い可能且つ係合可能なレバー係合凸部１９と、タンク２の外側においてタンク係合凸部２５より上方に設けられ下方へ突出するタンク突起２６と、レバー６の上部に設けられ、レバー６の操作により、タンク突起２６に内側からかみ合い可能なレバー突起２０と、を備えているため、タンク係合凸部２５にレバー係合凸部１９がかみ合った状態で、レバー６の第２ピン２２より下側部分が操作部４０として洗浄機本体１側へ押し込まれると、タンク係合凸部２５にレバー係合凸部１９が係合しタンク２が洗浄機本体１にロックされる。また、この状態から、レバー６の操作部４０が外方且つ上方へ引き上げられると、タンク係合凸部２５とレバー係合凸部１９との係合が解除されてロックが解除された後、レバー突起２０がタンク突起２６に内側からかみ合いタンク２が上方へ押し上げられる。このため、タンク２の洗浄機本体１からの取り出しを容易とすることができる。 As described above, according to the present embodiment, the lever 6 which is arranged on the outside of the washing machine main body 1 and is operated when the tank 2 is locked or unlocked, and the ends 10 and 10 are on the outside of the washing machine main body 1. The arm 7 is rotatably connected via the first pin 11 and the other ends 23, 23 are rotatably connected to the inside of the lever 6 via the second pin 22, and the tank 2 is rotatably connected to the outside of the tank 2. Is provided at a position above the first pin 11 when mounted on the washing machine main body 1, and is provided inside the tank engaging convex portion 25 protruding upward and the upper part of the lever 6, and by operating the lever 6, the tank is engaged. On the lever engaging convex portion 19 that can be engaged and engaged with the joint convex portion 25, the tank protrusion 26 that is provided above the tank engaging convex portion 25 on the outside of the tank 2 and projects downward, and the upper part of the lever 6. Since the tank protrusion 26 is provided with the lever protrusion 20 which is provided and can be engaged with the tank protrusion 26 from the inside by operating the lever 6, the lever 6 is in a state where the lever engaging convex portion 19 is engaged with the tank engaging convex portion 25. When the portion below the second pin 22 of the above is pushed toward the washing machine main body 1 side as the operating portion 40, the lever engaging convex portion 19 engages with the tank engaging convex portion 25 and the tank 2 locks to the washing machine main body 1. Will be done. Further, when the operating portion 40 of the lever 6 is pulled outward and upward from this state, the engagement between the tank engaging convex portion 25 and the lever engaging convex portion 19 is released, and after the lock is released, the lock is released. The lever protrusion 20 engages with the tank protrusion 26 from the inside, and the tank 2 is pushed upward. Therefore, the tank 2 can be easily taken out from the washing machine main body 1.

以上、本発明をその実施形態に基づき具体的に説明したが、本発明は上記実施形態に限定されるものではなく、例えば、上記実施形態においては、洗浄機１００に対する適用を述べているが、薬液タンクを着脱可能に搭載した背負式動力噴霧機等に対しても適用でき、要は、タンクを着脱可能に搭載する作業機全てに対して適用できる。 Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment, and for example, in the above embodiment, application to the washing machine 100 is described. It can also be applied to a backpack-type power sprayer or the like in which a chemical liquid tank is detachably mounted, and in short, it can be applied to all work machines in which a tank is detachably mounted.
