An embodiment of the present invention will be described in detail below with reference to the drawings.

A vacuum cleaner body 1 has a dust collecting chamber 3 for storing a dust bag 2 in the front and an electric blower storing chamber 5 for storing an electric blower 4 in the rear. 6 is an intake port formed in the front part of the dust collecting chamber 3, 7 is formed in the vicinity of the intake port 6, and the mouth plate 8 of the dust collecting bag 2 is locked in a direction in which it comes into pressure contact with the intake port 7. It is a clamp. Reference numeral 9 is a communication hole formed in the front wall of the dust collecting chamber 3, in which a tube 11 of an indicator 10 for displaying the amount of dust collected in the dust collecting bag 2 is arranged, and the indicator 10 and the inside of the dust collecting chamber 3 are connected to each other. Are in communication.

Reference numeral 12 denotes a dust collecting lid which covers the upper opening of the dust collecting chamber 3 so as to be openable and closable, and the clamp 7 is provided on the rear surface of the dust collecting lid 12.
When the dust collecting lid 12 is closed without attaching the dust collecting bag 2 to the dust collecting chamber 3, the clamp 7 is rotated to the inside of the dust collecting chamber 3. Because of the rib
The dust collecting lid 12 is prevented from closing by the contact of the clamp 13 with the clamp 7.

Reference numeral 14 is a front cover attached to the front part of the cleaner body 1, and forms a hose connection port 15 communicating with the intake port 6, and a bellows hose (not shown) is detachably connected to the hose connection port 15. It is supposed to do.

Reference numeral 16 is a support rib formed on the back side of the front cover 14, and by attaching the front cover 14 to the cleaner body 1, the indicator 10 is sandwiched between the support rib 16 and the cleaner body 1. It is supposed to do.

Reference numeral 17 denotes an inclined portion which is formed in a lower rear portion of the cleaner body 1 and which is inclined in a direction in which the height gradually increases toward the rear. This prevents the rear part of the cleaner body 1 from coming into contact with the floor surface when the part floats.

Reference numeral 18 denotes a recess formed in the longitudinal direction (lateral direction) below the rear surface of the cleaner main body 1, and the recess 18 and a support wall 19 constituting the lower portion of the recess 18 constitute a component storage 20. In addition, a gap attachment 21 for cleaning a gap or the like of furniture is held in the component storage section 20.

Reference numeral 22 denotes a holding claw formed at a position of the support wall 19 corresponding to the large diameter portion of the clearance attachment 21. When the clearance attachment 21 is stored in the component storage portion 20, the support wall 19 is provided. Due to the elastic force of the holding claw 22, the gap attachment 21 is held.

Reference numeral 23 is a reinforcing rib integrally formed in a direction substantially perpendicular to the support wall 19 at a substantially central portion of the lower surface of the support wall 19, that is, at a position corresponding to the small diameter portion of the clearance attachment 21 of the support wall 19. The strength of the support wall 19 is improved to prevent the support wall 19 from bending.

Reference numeral 24 denotes an auxiliary wheel pivotally supported by the reinforcing rib 23, which is located at the intersection of the inclined portion 17 of the cleaner body 1 and the rear surface, and a bellows hose (not shown) is pulled upward during cleaning. Thus, when the front part of the cleaner body 1 is lifted, the auxiliary wheels 24 come into contact with the floor surface and rotate, preventing the mobility of the cleaner body 1 from decreasing.

According to this configuration, the clearance attachment 21
Is stored in the component storage portion 20 on the rear surface of the cleaner body 1, and is held by the elasticity of the support wall 19 formed integrally with the cleaner body 1. With this configuration, it is not necessary to provide a separate component for holding the gap attachment 21, and the number of components is not increased.

On the lower surface of the support wall 19 of the component storage section 20,
Reinforcing ribs 23 are integrally formed in a direction orthogonal to the support wall 19, prevent the support wall 19 from being deformed, and attach the gap.
It is possible to surely hold 21 and to prevent the support wall 19 from being damaged when the support wall 19 is impacted and the support wall 19 is reinforced by the reinforcing ribs 23.

Further, the holding claw 22 is formed at a position corresponding to the large diameter portion of the clearance attachment 21 of the support wall 19, and the diameter of the clearance attachment 21 diameter of the support wall 19 is approximately at the center. At a position corresponding to the small portion, the reinforcing rib 23 is integrally formed in a direction orthogonal to the support wall 19, and by forming the holding portion of the gap attachment 21 and the reinforcing portion of the support wall 19 at positions separated from each other, The flexure of the support wall 19 can be prevented, the clearance attachment holding force of the holding claw 22 is not reduced by the flexure of the support wall 19, and the clearance attachment 21 can be reliably held.

[0025]

According to the configuration of claim 1 of the present invention, by integrally forming the component storage portion for storing the gap attachment in the cleaner body, it is not necessary to provide a separate component for holding the gap attachment. It does not increase the number of parts.

Further, by integrally forming the reinforcing ribs on the lower surface of the support wall of the component storage portion, the deformation of the support wall can be prevented and the attachment for the gap can be surely held, and the support wall is reinforced by the reinforcement ribs. It can be prevented from being damaged when a shock is applied to.

According to the second aspect of the present invention,
By forming the holding portion that holds the attachment for the gap and the reinforcing rib that reinforces the support wall at separate positions,
It is possible to reliably hold the gap attachment without reducing the holding force of the holding claws due to the bending of the support wall.
