に係合する段部７とが形成されている。Prior Art An example of the prior art will be explained based on FIG. 5. First, a cylindrical shaft 2 that protrudes downward and can be freely reduced in diameter is formed on the lower surface of the vacuum cleaner main body 1. At the lower end of this cylindrical shaft 2, locking claws 3 are positioned at front and back positions in the direction of movement.
The bracket 5 that holds the turning ring 4 has a bearing 6 that fits on the cylindrical shaft 2 and the locking pawl 3.
A step portion 7 that engages with the step portion 7 is formed.
考案が解決しようとする問題点

めである。Problems to be Solved by the Invention When the bracket 5 collides with an obstacle 8 while the vacuum cleaner main body 1 is moving, the locking claw 3 will close as shown in FIG.
There is a risk that an excessive load will be applied to the cylinder, causing the locking pawl 3 to be damaged or the bracket 5 to come off from the cylinder shaft 2. This is because the cylinder shaft 2 can be freely reduced in diameter.
また、筒軸２の部分は合成樹脂で形成されるた
め、縮径できないように内部に空間を形成しない
ようにすると、成形時の変形が大きくて寸法精度
がでないと云う欠点があり、実施することができ
ない。 In addition, since the cylinder shaft 2 is made of synthetic resin, if a space is not formed inside so that the diameter cannot be reduced, there is a drawback that the deformation during molding will be large and dimensional accuracy will be poor. I can't.
さらに、筒軸２と軸受６との嵌合部分にゴミ等
が侵入することが多く、ブラケツト５の回動を阻
害する。 Further, dirt and the like often enter the fitting portion between the cylinder shaft 2 and the bearing 6, which obstructs the rotation of the bracket 5.

させる。Means for Solving the Problem A plurality of protrusions are arranged in parallel to protrude downward with a space formed along the direction of movement in the front lower part of the vacuum cleaner body, and the outside of these protrusions is arranged in parallel. A supporting portion is formed by connecting the peripheral edges in a cylindrical shape, and a bearing of a bracket that holds the turning ring is fitted into this supporting portion.
作 用
支持部は複数の突片により形成されているが、
その方向は掃除機本体の進行方向に沿つた方向で
あり、これにより、ブラケツトが障害物に衝突し

い。Function The support part is formed by multiple protrusions,
The direction is along the direction of movement of the vacuum cleaner body, so that even if the bracket collides with an obstacle, the deformation of the support part is small, and this prevents the bracket from coming off the locking claw. Even if dirt enters the fitting portion, since there is a space between the protrusions, the rotation of the bracket will not be hindered.

ランプ２０とが設けられている。Embodiment An embodiment of this invention will be described based on FIGS. 1 to 4. First, the vacuum cleaner main body 8 consists of a main body case 9 and a dust case 10. The main body case 9 houses an electric blower 11 and a cord reel 12, and bearings 14 supporting wheels 13 are provided on both sides.
is formed. Further, a partition plate 16 is attached to the opening surface 15 of the main body case 9 on the suction side. A filter 17 is housed in the dust case 10, and the dust case 10 has a protrusion 19 held by a fixed locking part 18 formed at the lower part of the main case 9, and a clamp that engages with the upper part of the partition plate 16. 20 are provided.

方に形成されている。 Next, a support part 21 is integrally formed on the lower surface of the dust case 10, and a bracket 23 for holding a turning ring 22 is held on this support part 21. As shown in FIGS. 2 to 4, the support portion 21 has a plurality of protrusions 24 arranged in parallel in the direction of travel with a space 25 in between, and the outer peripheral edges of these protrusions 24 When tied together, they form a cylinder. The bracket 23 has a bearing 26 that fits into the cylindrical support 21. Further, locking pawls 27 for preventing the bracket from coming off are formed on both sides in the left-right direction of the support portion 21 to elastically engage with the bearings 26 of the bracket 23, and a stepped portion 28 with which these locking pawls 27 engage is formed. is formed below the bearing 26.

る等の効果を有するものである。Effects of the invention As described above, this invention arranges a plurality of protrusions in parallel that protrude downward with a space formed in the lower front part of the vacuum cleaner main body along the direction of travel, and these protrusions are arranged in parallel. The supporting part is formed into a cylindrical shape connecting the outer peripheral edges of the vacuum cleaner, and the bearing of the bracket is fitted into this supporting part, so that the supporting part is strong against external forces in the direction of movement of the vacuum cleaner body. As a result, the degree of deformation is small, so the engagement between the locking pawl and the stepped portion of the bearing does not come off, making it stable.Also, even if dirt enters the bearing, it will not fall out of the space. , the bracket always rotates smoothly.
