An electric vacuum cleaner is equipped with a dust collection unit ( 20 ) that can be detachably installed in the air passage en route from a suction unit to an electric fan of the cleaner. The dust collection unit ( 20 ) comprises a dust collecting case ( 21 ) for accumulating dust sucked in, a lid member ( 32 ) that can be opened to discharge the accumulated dust; and a lock mechanism (clamp lever) ( 33 ) for locking the lid member 32 tightly closed. The electric vacuum cleaner is further provided with a lid opening mechanism (lid opening stick ( 35 ) for forcibly opening the lid member ( 32 ) in cooperation with the lock mechanism locking the lid member. Even when the sealing pressure of the packing is high or when the accumulated dust does not weigh on the lid member because the dust is compacted on the inner wall of the dust collecting case, the lid member can be opened without difficulty to discharge the dust, without opening it by hand. Thus, the user can avoid handling unsanitary dust.
