Embodiment Construction

1>

[0017]Hereafter, a wheel body to which a weight device for model concerning an embodiment of the present invention is attached will be explained referring to FIG. 1. In the present embodiment, as shown in FIG. 1, a wheel 2 assembled with a tire 4 is referred to as a wheel body 1. In addition, the wheel body 1 of the present embodiment is used for a crawler-type RC car. The wheel body 1 has: a wheel 2; a weight device 3 for model (shown by broken lines in FIG. 1) attached to an outer periphery of the wheel 2 so as to extend along a circumferential direction A of the wheel 2; an annular sponge (not illustrated) attached to an outer periphery of the weight device 3; and a tire 4 attached to the wheel 2 while housing the annular sponge and the weight device 3 inside. Although the weight device 3 is used for the wheel body 1 of a crawler-type RC car, it is also possible to use the weight device 3 for the wheel body of other than the crawler-type RC car. Note that the circumferential di...

Abstract

In order to lower the center of gravity easily, the present invention provides a weight device 3 for model attached to an outer periphery of a wheel of a model car, the weight device 3 having: an annular case 10 extended along a circumferential direction A of the wheel, the annular case 10 having an annular internal space S; and a plurality of weight members 30 arranged in the annular internal space S. The weight members 30 are configured to be relatively movable in the circumferential direction A with respect to the annular case 10b when the annular case 10 is rotated in the circumferential direction A.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This patent specification is based on Japanese utility model application, No. 2019-4278 filed on Nov. 12, 2019 in the Japan Patent Office, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a weight device for model attached to an outer periphery of a wheel of a radio-controlled model car (hereafter, referred to as RC car).2. Description of the Related Art[0003]Patent Document 1 discloses an RC car for off-road. The above described RC car for off-road includes a crawler-type RC car which is used for traveling on a rocky road and over a low step, for example. In the above described crawler-type RC car, it is necessary to lower the center of gravity for traveling on a rough road such as a rocky road. In some cases, the center of gravity of the RC car is lowered by directly fixing weights to an outer periphery of a wheel and attaching t...
