Further, the handle body 25 is formed of synthetic resin into a substantially U-shape having side legs 36 extending at right angles to both ends, and the thickness h ₁ of the handle body 25 is equal to the width of the storage recess 26.
The handle body 2 is formed to have approximately the same dimensions as the depth _h2 of the handle body 2.
5 stored in the storage recess 27, the main case 2
It is designed to be approximately on the same plane as the top surface of 0.

In addition, the dimension l ₁ between the outer surfaces of the both side legs 36 of the handle body 25 is shorter than the width l ₂ of the storage recess 26, and a protrusion is provided at the tip of the outer side of the both side legs 36 of the handle body 25. The dimension between the tips of the shaft 37 rotatably engaged with the shaft support hole 34 is longer than the width l ₂ of the storage recess 26, and this shaft 37 is connected to the handle body 25.
The space between the side leg portions 36, 36 is narrowed using the elasticity of the synthetic resin, and the shaft is rotatably supported in the shaft support hole 34.

Next, 38 is a handle holder, and the fitting concave stepped portion 27
It is designed to be mated to. A protrusion 39 that is engaged with the engagement hole 29 is provided on the front surface of the handle holder 38, and a hook-shaped protrusion (not shown) that is engaged with the engagement hole 30 is provided on the lower rear surface of the handle holder 38. is installed protrudingly. The front part of the handle holder 38 also serves as a cover for the dust collection meter 31, and is designed to cover and hold the dust collection meter 31 supported on the pedestal 32. A viewing window 40 for the dust collection amount meter 31 is formed in the front part of the dust collection meter 38 .

Note that a cover portion 42 of the connector 35 is integrally formed in the front portion of the handle holder 38.

Next, the operation of this embodiment will be explained.

The handle body 25 is attached by deforming its both side legs 36 inward against elasticity, narrowing the space between the both side legs 36, and inserting a shaft 37 into a shaft support hole formed on both sides of the storage recess 26 of the main case 20. 34, the dimensions of both side legs 36 are returned to their original values by restoring force, and the shaft 37 is rotatably supported in the shaft support hole 34. Next, the protrusion 39 on the front side of the handle holder 38 is engaged with the engagement hole 29, and the protrusion on the rear side is engaged with the locking hole 30, so that the fitting concave stepped portion 27
Fits in. In this state, both outer surfaces 38a, 38a of the handle holder 38 are opposed to inner surfaces 36a, 36a of the side legs 36 of the handle body 25, and the side legs 36 of the handle body 25 have a shaft 37 extending from the shaft support hole 34. Movement in the direction of disengagement is regulated, and the axial engagement dimension between the shaft 37 and the shaft support hole 34 is the dimension of the gap 41 between the inner surface 36a of the side leg 36 and the outer surface 38a of the handle holder 38. Since they are each longer than _l5 , the shaft 37 will not come off.

When the handle body 25 is not in use, the handle body 25 is stored in the storage recess 26 as shown in FIG. In this state, the handle body 26 is approximately flush with the top surface of the main body case 1, and the dust collection amount meter 31 can be checked from the front side and the rear side of the main body case 20 without the handle body 26 getting in the way. It is suitable as a vacuum cleaner whose top surface can be used as a seat, and it can be easily packed without protruding from the top surface of the main body case 20.

In addition, when the main body case 20 is transported, when the handle body 25 is raised, the handle body 25 rotates around the shaft 37 and assumes a vertical shape. All of the forces are applied to the shaft support hole 34 of the main body case 20.

Moreover, the movement of the handle body 25 in the width direction is controlled by the handle holder 3.
8, and its movement is smaller than the axial engagement dimension between the shaft 37 and the shaft support hole 34, so that the shaft 37 does not come off from the shaft support hole 34.

[Effect of idea]

According to the present invention, a handle holder is provided in the storage recess formed on the upper surface of the main body case, and is mounted between both legs of a substantially U-shaped handle body, so that the axis of the handle body and the main body case are supported. The axial engagement dimension with the hole is made larger than the gap between the inner surface of the side leg of the handle body and the outer surface of the handle holder, so when the handle body is grasped and lifted, the handle body This means that the main body case has to be lifted directly, and sufficient strength can be obtained by simply reinforcing the periphery of the shaft support hole in the main body case, and the amount of movement of the handle body in the direction in which the shaft and the shaft support hole are disengaged is sufficient. It is possible to use a locking means that can control the movement of the handle, prevent the handle body from coming off accidentally, reduce the size of the handle holder without applying any load when the handle is gripped, and easily attach and detach the handle holder.
