    • A water gun (1) has a casing (10), a rear grip portion (12) and a front grip portion (11). The casing (10) incorporates a pump mechanism (40) and includes pumping tubing (50) which makes up a pumping path through which water is pumped up from a water storage tank by the pumping mechanism and a muzzle portion (4) which is disposed at a front end of the casing (10). The pump mechanism (40) is made up of a first cylinder (20) and a second cylinder (30) which are oriented in opposite directions to each other and includes a first piston (21) slidable forwards and backwards within the first cylinder (20) and a second piston (31) slidable forwards and backwards within the second cylinder (30), an interlocking member that is coupled to the first piston (21) and the second piston (31) and which is brought into engagement with a rear half portion of the casing, pumping check valves (41), a jet water flowing chamber (22) and a water supply path (52).
    • 水枪(1)具有壳体(10),后把手部分(12)和前把手部分(11)。 壳体(10)包括泵机构(40)并且包括泵送管道(50),泵送管道(50)构成泵送路径,泵通过泵送路径从储水箱泵送水,并且设置有喷嘴部分(4) 在壳体(10)的前端处。 泵机构(40)由第一气缸(20)和第二气缸(30)构成,第一气缸(20)和第二气缸(30)彼此相反地定向,并且包括可在第一气缸(20)内向前和向后滑动的第一活塞 )和第二活塞(31),所述第二活塞(31)在所述第二气缸(30)内可向前和向后滑动;联锁构件,其联接到所述第一活塞(21)和所述第二活塞(31)并且与所述第二活塞 套管的一部分,抽吸止回阀(41),喷射水流动室(22)和供水路径(52)。
