Thereby, the locking member 13d ₁ is detached from the through hole 13b ₁₁₄ of the L-shaped rib 13b ₁₁₃ of the battery cover 13b. Then, by the urging force of the compression coil spring 13b ₅ for biasing the battery cover 13b upward, the battery cover 13b is opened automatically rotates upward (in the direction of the arrow A) about the shaft portion 13b _3. When the operation lever 13d ₂ is released, the locking member 13d ₁ moves backward by the urging force of the compression coil spring 13d ₃ (see FIG. 18).

Further, when the battery cover 13b rotates in the arrow A direction, the sliding projection 13b ₄ slides on the inclined surface portion 13c ₃ of the support member 13c. At this time, as the slide convex portion 13b ₄ can smoothly slide on the inclined surface portion 13c _3, the tip of the slide convex portion 13b ₄ are formed into a shape having a convex curved surface.

In FIG. 16 (A) and (B), shows a first step of the open state of the battery cover 13b by the compression coil spring 13b _5.

Since the battery 30 is pulled out to some extent, the force required to pull the battery 30 backward is reduced. For example, even if the user is a woman, it can be pulled out with a light force.

On the other hand, the attachment of the battery 30 to the cleaner body 10 may be performed in the reverse manner to the operation of pulling out the battery 30 from the cleaner body 10. At this time, may be pushed to the battery 30 to the extent that passes through the stopper protrusion 13e ₁ into the battery accommodating recess 13a, it is not necessary to completely push the battery 30 all the way into the battery housing recess 13a (see FIG. 18). Also, the battery 30 passes through the stopper projection 13e _1, since protrudes stopper protrusion 13e ₁ you hear a "click", the user can obtain a feeling operation by listening to the sound.

As shown in FIG. 18, when the battery cover 13 b is rotated in the direction of arrow B and closed, the pushing contact portion 13 b _{112 of} the battery cover 13 b is in sliding contact with the rounded rear end portion of the battery 30. Push forward. Then, by closing the battery cover 13b completely, the battery 30 is completely pushed into the battery housing recess 13a by the pushing contact portion 13b ₁₁₂ .

As a result, the positive and negative terminals of the battery 30 are in electrical contact with the terminal portions 43. At this time, the locking member 13d ₁ is retracted by the L-shaped ribs 13b ₁₁₃ descending the battery cover 13b is in sliding contact with the inclined surface of the locking member 13d _1, the locking member 13d ₁ is fitted into the subsequent through-hole 13b ₁₁₄ The battery cover 13b is kept closed by being locked.
