１１１１の隙間ＳＩが設けられている。Further, the wheel 22 has a rotating shaft 25 provided in the center, and the bearing engages with the portion 23, and the claw 26 at the tip of the rotating shaft 26 is inserted into the hole 22.
It locks onto the edge of 4 to prevent it from falling out. Furthermore, in order to prevent the wheel 22 from rubbing against the main case 722 even if the wheel 22 rotates, there are 3 to 411 holes between the wheel 22 and the main case 21.
A gap SI of 1111 is provided.
上記の構成によシミ気掃除機は床面を自在に移動できる
ようになっている。The above configuration allows the stain cleaner to move freely on the floor.

を通過して外部に漏れる。Problems to be Solved by the Invention In the structure of the conventional mounting of the wheel 22, the claws 26
In order to provide this, the claw height HI needs to be about 5 mm, and since the claw 26 rotates with the rotation of the wheel 22, there should be electrical wires for internal wiring in the vicinity that are dangerous if they come into contact with the claw 26 and wear out. could not be set up. Also wheels W
I, the gap SI, the wall thickness of the main body case 21, etc. cannot be made thinner or narrower due to their functions. Therefore, the widthwise dimension of the vacuum cleaner has to be increased by twice the claw height HI, which is an obstacle to making the vacuum cleaner smaller and lighter. Furthermore, since the cylindrical bearing has the hole 24 of the part 23 penetrating into the main case 21, the exhaust air discharged from the motor flows in the direction of arrow A and passes between the hole 24 and the rotating shaft 25. and leak to the outside.
この気流は電気掃除機の運転騒音が高くなる要因の１つ
となっていた。This airflow was one of the factors that increased the operating noise of the vacuum cleaner.
本発明はこのような課題を解決するもので、電気掃除機
本体の幅を大きくせず、運転騒音を高くしない車輪の取
シ付は機構を提供することを目的とするものである。The present invention is intended to solve these problems, and it is an object of the present invention to provide a mechanism for mounting wheels that does not increase the width of the vacuum cleaner body and does not increase operating noise.
課題を解決するための手段
この目的を達成するために本発明は、電気掃除機の主体

しないように形成したものである。Means for Solving the Problems In order to achieve this object, the present invention arranges wheels for movement at the bottom of the rear part of the main case of a vacuum cleaner, and provides a rotating shaft that projects integrally with the wheels, and the rotating shaft A cylindrical bearing for rotatably holding the main body is provided integrally with the rear side surface of the main case, and the cylindrical bearing is formed so that the hole in the part does not penetrate into the main case.
作 用
この構成によｐ１車輪の回転軸端面に設けた固定用の爪
が主体ケーヌ内に露出しないので、内部配線などが車輪
数シ付は部近傍に配設されても、内部配線などが車輪の
回転軸により摩耗し、損傷をうけることがなくなる。Function: With this configuration, the fixing claw provided on the end face of the rotating shaft of the P1 wheel is not exposed inside the main body, so even if the internal wiring etc. is arranged near the wheel part, the internal wiring etc. No more wear and tear caused by the rotating shaft of the wheel.
また、主体ケースと一体的に設けた軸受は部の孔が主体
ケース内部に貫通していないため、車輪数シ付は部よシ
モータの排気風が漏れて、運転音が高くなることはない
。In addition, since the hole in the bearing provided integrally with the main case does not penetrate into the inside of the main case, the exhaust air from the motor will not leak out from the bearing with several wheels, which will prevent high operating noise.
さらに、車輪の固定爪が主体ケース内部に露出しない構
造になっているので、両側の車輪の爪の高さの分だけ主
体ケースの全幅を小さくすることができ、電気掃除機の
小型化がはかれることとなる。Furthermore, since the fixed claws of the wheels are not exposed inside the main case, the overall width of the main case can be reduced by the height of the wheel claws on both sides, making the vacuum cleaner more compact. It happens.
実施例 以下、本発明の実施例を図面を用いて説明する。Example Embodiments of the present invention will be described below with reference to the drawings.

されている。FIG. 1 and FIG. 2 show the structure of a vacuum cleaner according to an embodiment of the present invention. As shown in FIG. 1, the main body case 71 has a dust lid 2 and an upper podium 3 placed on its upper part, and a small rotating wheel 4 and a wheel 5 for floor movement are rotatably held on the bottom surface.
第１図のＡ−Ａ線断面を第２図に示す。図に示すように
床移動用の車輪６はその中央部に円筒状の回転軸６が一
体的に設けられ、回転軸６の先端には爪７が設けられて
いる。FIG. 2 shows a cross section taken along line A--A in FIG. 1. As shown in the figure, the floor moving wheel 6 is integrally provided with a cylindrical rotating shaft 6 at its center, and a claw 7 is provided at the tip of the rotating shaft 6.
車輪６を保持する主体ケー７１の後部側面には、回転軸
６が孔８を回転Ｕゆう動する円筒状の軸受は部９が一体
的に形成されている。A cylindrical bearing part 9 is integrally formed on the rear side surface of the main body case 71 that holds the wheels 6, through which the rotary shaft 6 rotates through the hole 8.

になっている。Further, in the above-mentioned bearing, the portion 9 has its hole 8 as shown in FIG.
is injection molded using a mold 11 with a U-shaped cross section that moves parallel to the rear side wall 1o of the main case 1 in the direction of the arrow, and a mold 12 with a circular cross section that moves perpendicular to the plane of the paper, as shown in FIG. As shown in FIG. 2, the hole 8 is formed so as not to penetrate into the main body case 1 due to the side wall 1o. The pawl 7 of the rotary shaft 6 engages with the stepped portion of the hole wall of the bearing portion 9 to prevent it from coming out.

ことができる。In the above configuration, as shown in FIG.
By not allowing the hole 8 in part e of the bearing integrally provided in the main body case 1 to penetrate into the inside of the main body case 1, the exhaust air from the motor (not shown) provided in the main body case 1 will not leak through the bearing part 9. Therefore, the noise during operation of the vacuum cleaner does not leak out from the bearing part, and the noise of the vacuum cleaner can be reduced.

はない。Further, since the pawls 7 of the wheels 5 are not exposed inside the main case 1, there is no fear of damage even if internal wiring etc. are installed in the space near the side wall 1o. Furthermore, the wheel width W shown in the conventional example in FIG.
The side wall 1o in FIG. 1 can be narrowed in the direction of the arrow by the height HI of the pawl 26 without changing the gap SI between the wheel 22 and the main case 21. As a result, as shown in FIG. 4, the outer width W2 of the wheel 6 can be narrowed to W3, and the front width W4 of the vacuum cleaner can be reduced. As is clear, in the vacuum cleaner of the present invention, the bearing for rotatably holding the floor moving wheels provided on the rear side of the main case is provided so that the hole in the part does not communicate with the inside of the main case. The fixing pawl provided on the wheel is not exposed inside the main body cake, and even if the internal wiring is provided near the bearing, it will not be damaged by the pawl of the wheel.
また、軸受は部よシモータの排気風が漏れて電気掃除機
の運転騒音が大きくなることがない。In addition, the bearing prevents the exhaust air from the motor from leaking and increasing the operating noise of the vacuum cleaner.
また、車輪幅や車輪と主体ケースとの隙間間隔を狭める

気掃除機の全体幅も小さくすることができるという効果
が得られる。Further, since the outer width of the wheel can be reduced without narrowing the wheel width or the gap between the wheel and the main case, the overall width of the vacuum cleaner can also be reduced.
