Provided is an electric vacuum cleaner having an operating portion capable of pushing down the lock claw against the force.

According to the electric vacuum cleaner of the present invention, the battery can be mounted on the battery mounting portion provided at the rear of the canister type vacuum cleaner body, and the lock claw can be locked in the locking recess to lock the state. The battery can be removed from the battery mounting part by pushing down the part and removing the lock claw from the locking recess.
In particular, according to the battery mounting portion and the locking mechanism portion in the present invention, when removing the battery, the user, for example, holds down the upper and lower surfaces of the battery with the thumb and the index finger while pushing down the operation portion with the thumb (or index finger) and pulls out the battery. Because it can be done, the battery can be easily removed.

In other words, in the battery removal operation, the index finger (or thumb) is placed on the upper surface of the battery, and the thumb (or index finger) is placed on the lower surface of the battery while pushing the operation unit downward with the thumb (or index finger). Since the upper and lower surfaces of the battery can be grasped and pulled out backward, even a user with a small hand or a weak grip can easily grasp the battery and pull it out easily. At this time, the operation direction of the operation part is downward, and the direction of pulling out the battery is backward, so you can easily pull out the battery from the battery mounting part with one hand without holding it with another hand so that the vacuum cleaner body does not move. Can be done.
