Is a main body with a built-in motor, and forms a dust collection chamber 13 opened and closed by a dust collection chamber lid 12 in the front. The dust collection chamber 13 is provided with a suction port 15 at a front portion thereof to which a hose 14 is detachably attached, and a paper bag 16 inside thereof. Reference numeral 17 denotes a front wheel, which is composed of a roller 18 at a tip portion and a support body 19 having a rotation shaft 20 at a base portion. It is rotatably attached to the main body 11 at 20a. The main body 11 has a plurality of recesses 21 (A, B, from top to bottom) at a position facing the support 19 near the bearing hole 20a.
C), the support 19 includes a main body 11 near the rotary shaft 20.
The coil spring 2 built in the support 19 on the side facing the
2 is provided with a convex portion 23 urged by an elastic body.
The support 19 can be held at a plurality of constant angles by fitting the plurality of recesses 21 into the plurality of recesses 21. Also, this support 1
The rotating shaft 20 of 9 is located on the rear side of the main body 11 with respect to the roller 18. Reference numeral 24 is a pair of rear wheels rotatably attached to the main body 11.

If the convex portion 23 provided on the support 19 of the front wheel 17 is fixed to A of the concave portion 21 of the main body 11, the main body 11 can be cleaned in a substantially horizontal state as in the present situation. When the convex portion 23 is fixed to B or C of the concave portion 21, the main body 11 is held by the support body 19 which is inclined upward, so that the intake port 15 to which the hose 14 is attached is lifted from the floor surface and is inclined. Therefore, the hose 14 can be effectively cleaned up to a height higher than its length. Further, if the convex portion 23 is fixed to B or C of the concave portion 21, the distance D between the rear wheel 24 and the front wheel 17 is narrowed, so that the cleaner main body can easily make a small turn and cleaning work can be easily performed.

りしやすく掃除作業もしやすい。As is apparent from the above description of the embodiments, according to the electric vacuum cleaner of the present invention, the front wheel provided on the bottom surface of the main body of the vacuum cleaner is fixed in a plurality of stages about the rotation axis. Since it is possible to hold the main body of the vacuum cleaner by tilting it upward, the intake port to which the hose is attached is lifted from the floor surface and becomes oblique, so it is effectively higher than the length of the hose. You can clean up to that point. Further, since the main body of the vacuum cleaner is held so as to be inclined upward, the gap between the rear wheel and the front wheel is narrowed, so that the main body of the vacuum cleaner can easily make a small turn and can easily perform cleaning work.
