関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure for mounting a support shaft at the center of a rotating body, for example, when mounting an axle on a wheel of an assembled automobile toy.
（従来の技術及び解決すべき課題） 従来の組立て自動車玩具に於て、車輪取付構造は、第４
図に示す如く、全体がゴムにて形成された車輪（2a）の
中心に穴径が車軸（1a）の直径より小さい軸穴（60）を
開設し、該穴に車軸（1a）を緊密に挿入している。(Prior Art and Problems to be Solved) In the conventional assembled automobile toy, the wheel mounting structure is the fourth one.
As shown in the figure, at the center of the wheel (2a) made entirely of rubber, make a shaft hole (60) with a hole diameter smaller than the diameter of the axle (1a), and close the axle (1a) tightly in the hole. Inserting.
この構造は、車輪全体がゴムにて形成されているため、
軸径に多少のバラツキがあっても、軸の取付けに支障は
無いが、ゴムがフレキシブルであるがために軸に対する
車輪の振れに対する保持力は弱く、走行中に軸（1a）に
対して車輪（2a）が振れる。In this structure, the entire wheel is made of rubber,
Even if there is some variation in the shaft diameter, it will not hinder the shaft installation, but since the rubber is flexible, the holding force against the runout of the wheel against the shaft is weak, and the wheel against the shaft (1a) during running. (2a) swings.
又、車輪全体をゴムにて形成すると、実際の自動車の車
輪を模してホィールの外周にタイヤを装着したデザイン
は形成出来ない。Further, if the entire wheel is made of rubber, it is not possible to form a design in which a tire is mounted on the outer periphery of the wheel in an imitation of an actual vehicle wheel.
合成樹脂製のホィールにタイヤを装着した玩具用の車輪

び車軸の軸径に高い寸法精度が要求される。Wheels for toys in which tires are attached to wheels made of synthetic resin are also used, but in this case, high dimensional accuracy is required for the shaft insertion hole of the wheel and the shaft diameter of the axle.
又、車軸と車輪との組立て、分解を繰り返すと、車輪に
対する車軸の嵌合が緩くなり、走行中に車輪が外れるこ
とがあった。Further, when the assembly and disassembly of the axle and the wheel are repeated, the fitting of the axle to the wheel becomes loose, and the wheel sometimes comes off during traveling.

（６）に嵌合している。(Means for Solving the Problems) In order to achieve the above object, the support shaft mounting structure for a rotating body of the present invention has an elastic member insertion hole (5) at the center of the rotating body (2), and the bottom of the hole. A shaft insertion hole (6) concentric with the hole and having a diameter smaller than that of the hole and a closed rear end is opened, and an elastic member (7) formed of synthetic rubber or the like in the elastic member insertion hole (5).
Is tightly inserted, the support shaft (1) is tightly fitted and inserted through the shaft hole (71) opened at the center of the elastic member (7), and the support shaft (1) The penetrating end is fitted in the shaft insertion hole (6).

該弾性部材（７）の貫通軸孔（71）に対し、該孔径より
太い支持軸（１）を弾性部材（７）を弾性変形させて緊
密に貫通させ、貫通端を軸挿入穴（６）に嵌める。(Operation and effect) To assemble the rotating body (2) and the support shaft (1), the elastic member (7) is tightly fitted into the rotating body (2) in a compressed state,
With respect to the through shaft hole (71) of the elastic member (7), the elastic member (7) is elastically deformed to tightly penetrate the support shaft (1) having a diameter larger than the hole diameter, and the through end is the shaft insertion hole (6). Fit in.

挿入穴（５）の内面を一層強固に押圧し、該挿入穴から
弾性部材（７）が外れることは防止される。When the support shaft (1) is inserted into the elastic member (7), the shaft hole (71) of the elastic member (7) is expanded outward as the shaft enters, and the outer peripheral surface of the elastic member (7) is rotated. The inner surface of the elastic member insertion hole (5) of (2) is pressed more firmly to prevent the elastic member (7) from coming off the insertion hole.
支持軸（１）の弾性部材（７）への貫通部は弾性部材
（７）によって軸心側に強く押圧されており、支持軸
（１）を強く引っ張らない限り、弾性部材（７）から支
持軸（１）が抜けることはない。The penetrating portion of the support shaft (1) into the elastic member (7) is strongly pressed toward the axial center by the elastic member (7) and is supported by the elastic member (7) unless the support shaft (1) is strongly pulled. The shaft (1) will not come off.
従来の様に挿入穴（６）と軸（１）の緊密嵌合によって
軸の抜止めを画る必要はなく、軸と軸挿入穴（６）の寸
法精度は、軸がガタツクことのない程度の精度で可い。Unlike the conventional case, it is not necessary to define the shaft with a tight fit between the insertion hole (6) and the shaft (1), and the dimensional accuracy of the shaft and the shaft insertion hole (6) is such that the shaft does not rattle. It is possible with the accuracy of.
更に、前記の如く、支持軸（１）の先端側を包囲してい

にて緊密に嵌まっており、回転体（２）に対する軸の振
れは抑えられ、然も、支持軸（１）の先端は、回転体
（２）の軸挿入穴（６）に嵌合しているため、軸は軸挿
入穴（６）と圧縮した弾性部材（７）の２箇所で保持さ
れ、軸挿入穴（６）と軸（１）との嵌合が緊密でなくて
も、回転体（２）に対する軸（１）の振れを殆ど無くす
ことが出来る。Further, as described above, the elastic member (7) surrounding the tip side of the support shaft (1) is tightly fitted in the hole (5) of the rotating body (2) in a compressed state, Shaking of the shaft with respect to 2) is suppressed, and since the tip of the support shaft (1) is fitted in the shaft insertion hole (6) of the rotating body (2), the shaft is inserted into the shaft insertion hole (6). Even if the shaft insertion hole (6) and the shaft (1) are not tightly fitted to each other, the shaft (1) is prevented from swinging with respect to the rotating body (2). You can almost eliminate it.
回転体（２）から軸（１）を引っ張ると軸は弾性部材
（７）から外れ、或は軸に付いたまま弾性部材（７）が
穴（５）から外れて容易に分解でき、前記手順にて簡単
に組立て出来る。When the shaft (1) is pulled from the rotating body (2), the shaft is disengaged from the elastic member (7), or the elastic member (7) is disengaged from the hole (5) while being attached to the shaft and can be easily disassembled. Can be easily assembled.
従来の様に軸と回転体との緊密な嵌合によって軸と回転

手指を負傷させる虞れはない。更に、回転体（２）の外
側からは支持軸（１）は見えず、支持軸（１）を隠すた
めの塞ぎ板は不要である。Since the shaft and the rotating body are not engaged by tight fitting between the shaft and the rotating body as in the past, even if the assembly and disassembly of the shaft and the rotating body are repeated, the relationship between the shaft and the rotating body is reduced. It never gets loose. Further, since the shaft insertion hole (6) is closed at the rear end, there is no risk of the shaft penetrating and injuring fingers when the shaft (1) is fitted into the hole (6). Furthermore, the support shaft (1) is not visible from the outside of the rotating body (2), and a closing plate for hiding the support shaft (1) is unnecessary.
