係止させている。この係止部5bにより、車輪取付台５は
下方への移動が制限される。The caster body 2 includes a mounting shaft 1b formed on a bottom surface 1a.
A wheel support 5 attached to the shaft support 3 via a coil spring 4, and a wheel 6 rotatably supported at the rear of the wheel mount 5. I have. The shaft support plate 3 is formed with a bearing portion 7 as a recess into which the mounting shaft 1b is immersed, and has an annular contact portion 7a formed on the periphery of the bearing portion 7 on the surface side of the shaft support plate 3, On the back side of the shaft support plate 3, there is an annular recess 7 b formed on the outer peripheral edge of the bearing 7. The shaft support plate 3 inserts the reduced diameter portion 1c at the tip of the mounting shaft 1b into the hole 7c at the bottom of the bearing portion 7 so that the annular contact portion 7a is in contact with the contact surface 1d of the peripheral edge of the mounting shaft 1b. It is positioned and held on the mounting shaft 1b and rotates freely 360 degrees in the horizontal direction. The coil spring 4 is disposed so as to be wound around the outer wall of the bearing portion 7, and one end of the coil spring 4 elastically contacts the bottom of the annular recess 7b.
The other end is in elastic contact with the wheel mount 5. The wheel mount 5
The shaft 5a formed at the distal end is rotatably mounted in the shaft hole 3a of the shaft support plate 3, and the locking portion 5b is locked to the locking portion 3b of the shaft support plate 3. The locking portion 5b restricts the downward movement of the wheel mounting base 5.

触面1dに当接させた軸支板３を介して水平方向に自在に
回動すると共に、コイルスプリング４の勢力に抗して随
時上方に移動する（第８図参照）。For this reason, the wheel mounting base 5 (see FIG. 7) constantly urged downward by the coil spring 4 can freely move in the horizontal direction via the shaft support plate 3 in which the annular contact portion 7a is in contact with the contact surface 1d. While rotating, it moves upward at any time against the force of the coil spring 4 (see FIG. 8).

形力は、環状凹部7bの内側壁である筒状軸部の上端部を
半径方向又は中心方向に変形させる力として作用する。[Problem to be Solved by the Invention] In FIGS. 7 and 8, one end of the coil spring 4 is always provided at the bottom of the annular recess 7b of the shaft support plate 3 (the wall above the annular recess 7b in the figures). The part is in contact with the bullet. The elastic force of the coil spring 4 on the bottom of the annular recess 7b acts as a deforming force on the bottom of the annular recess 7b. Then, this deforming force acts as a force for deforming the upper end portion of the cylindrical shaft portion which is the inner wall of the annular concave portion 7b in the radial direction or the center direction.
しかも、環状凹部7bの底部に作用する弾接力はコイル
スプリング４の一端が当接する部分が最も大きいため、
環状凹部7bの底部に作用する変形力はコイルスプリング
４の一端が当接している部分が局部的に大きい。Moreover, since the elastic contact force acting on the bottom of the annular concave portion 7b is greatest at the portion where one end of the coil spring 4 contacts,
The deformation force acting on the bottom of the annular concave portion 7b is locally large at a portion where one end of the coil spring 4 is in contact.
これらの結果、環状凹部7bの内側壁である筒状軸部の
上端部は半径方向又は中心方向に一様に変形せずに不規

た。As a result, the upper end portion of the cylindrical shaft portion, which is the inner wall of the annular concave portion 7b, deforms irregularly without uniformly deforming in the radial or center direction, so that the protruding state of the annular contact portion 7a also changes. Then, the state in which the annular contact portion 7a protrudes toward the contact surface 1d will change with time. Due to this change with time, the pivot plate 3
There is a problem that the smooth movement of the camera is hindered.

車輪取付台22の突出部32には、軸受け32aに回転軸23aを
回動自在に保持させた車輪23が装着されている。The shaft support plate 21 is provided with the reduced diameter portion 13 at the opening 28a of the bearing portion 28.
Is inserted so that the bottom of the bearing portion 28 is located between the step portion 12a and the locking portion 13a, and is mounted so as to include the mounting shaft 12. At this time, the bearing portion 28 is fixed to the annular contact portion 29 by the locking portion 13a.
Is in contact with the contact surface 14 and the bearing portion 28 is freely rotatable 360 degrees in the horizontal direction, and is positioned and held on the mounting shaft 12 without falling. The bearing portion 28 is covered with the elastic body receiving base 24 fitted into the recess 28b. Also, on the shaft support plate 21, the shaft 26a is inserted into the bearing 31a, the locking portion 33 is locked with the locking portion 27a, one end 25a is elastically contacted with the flange 24a, and the other end 25b is mounted on the wheel mounting base. The wheel mounting base 22 is mounted via a coil spring 25 elastically contacting the back surface of the base 22.
On the protruding portion 32 of the wheel mounting base 22, a wheel 23 having a rotating shaft 23a rotatably held by a bearing 32a is mounted.

を反発させるように付勢するコイルスプリング25と両係
止部27a,33により、後部（車輪23側）が若干傾斜した状
態に保持される（第２図参照）。Therefore, the rear portion (wheel 23 side) of the wheel mounting base 22 is slightly inclined by the coil spring 25 and the locking portions 27a and 33 that urge the shaft mounting plate 21 and the wheel mounting base 22 to repel each other. (See FIG. 2).
次に、上記構成を有する電気掃除機のキャスター体の
作用を説明する。Next, the operation of the caster body of the vacuum cleaner having the above configuration will be described.
例えば、床上にある本体11は、床面に接触させた車輪
23により床上を自在に移動させることができ、車輪23に
外力が加わっていない場合には、後部（車輪23側）が若
干傾斜した状態に保持されている（第２図参照）。For example, the main body 11 on the floor is a wheel that is in contact with the floor surface.
23 allows it to be moved freely on the floor, and when no external force is applied to the wheels 23, the rear portion (wheel 23 side) is maintained in a slightly inclined state (see FIG. 2).
一方、本体11の移動により、車輪23が敷居等の障害物
を乗り越そうとして車輪23を押し上げる方向に外力が加
わった場合、車輪取付台22は、付勢力に抗してコイルス
プリング25を圧縮させ、軸26aを回動軸として上方へと
回動する（第３図参照）。やがて、車輪23が障害物を乗
り越してしまうと、コイルスプリング25の付勢力によ
り、車輪取付台22は元の状態に戻る。このような動作に
より、コイルスプリング25は、車輪23に加わる外力を吸
収し、外力を本体に直接伝えない働きをしている。On the other hand, when an external force is applied in a direction to push up the wheel 23 to move over an obstacle such as a threshold due to the movement of the main body 11, the wheel mount 22 compresses the coil spring 25 against the urging force. This causes the shaft 26a to rotate upward about the rotation axis (see FIG. 3). Eventually, when the wheel 23 gets over the obstacle, the wheel mount 22 returns to the original state by the urging force of the coil spring 25. By such an operation, the coil spring 25 has a function of absorbing an external force applied to the wheel 23 and not directly transmitting the external force to the main body.
このとき、圧縮させられたコイルスプリング25の弾発
力は、コイルスプリング25の一端25aが弾接している弾
性体受台24により受け止められる。加えて、環状凹所30
の底部と凹部28bとの間には、間隙ｄが形成されてお
り、弾発力により例えフランジ24aが変形したとして
も、弾発力が直接環状凹所30に加わることはない。At this time, the resilient force of the compressed coil spring 25 is received by the elastic body receiving table 24 with which one end 25a of the coil spring 25 is in elastic contact. In addition, the annular recess 30
A gap d is formed between the bottom of the groove and the concave portion 28b. Even if the flange 24a is deformed by the elastic force, the elastic force is not directly applied to the annular recess 30.
従って、弾性体受台24は緩衝部材として機能し、弾発
力は、弾性体受台24及び弾性体受台24を介して軸受部28
全域に分散されることとなり、環状接触部29に直接加わ
ることがなく、環状接触部29の変形を防止することがで
きる。Therefore, the elastic support 24 functions as a cushioning member, and the elastic force is applied to the bearing portion 28 via the elastic support 24 and the elastic support 24.
Since it is distributed over the entire area, it is not directly applied to the annular contact portion 29, and the deformation of the annular contact portion 29 can be prevented.
このため、環状接触部29と接触面14との適正な接触が
保たれ、軸支板21の滑らかな回動を常時確保することが
できる。Therefore, proper contact between the annular contact portion 29 and the contact surface 14 is maintained, and smooth rotation of the shaft support plate 21 can be always ensured.
