Abstract (in Japanese) (See Japanese page) 
(in English) We participated in the mini 4WD wireless power feed running race held in Kanazawa in September
2018, and received a special prize. In this paper, we describe the background and design process of the coupler
mounted our mini 4wd. Firstly, our motivations to join the race are (1) discovering new advantages of capacitive
coupling, (2) disseminating the advantages of capacitive coupling, and (3) running the whole distance on the race.
Next, we clarify the minimum necessary coupling coefficient and coupling capacity of the coupler to achieve (3). We
focus on the softness of capacitive coupler, and propose a coupler that takes advantage of the softness. As a result
of small signal measurement of the coupler, it is confirmed that the coupler achieves (3). On the race day our mini
4wd finished in about 55 seconds.
