PROBLEM TO BE SOLVED: To realize a wheel detector easily installed on a job site.SOLUTION: In a wheel detector 30 including: a transmitter 33 for transmitting an aerial propagation signal; receivers 27, 29 for receiving the aerial propagation signal; and a determination part 31 for determining the presence or absence of a wheel 11 according to the quality of a reception state of these receivers, it is possible to finish in advance the adjustment relating to the correlation of the transceivers, the signal level and the like at a plant and an inspection room by attaching the transceivers 27, 29, 33 to one holding member 34 attached to one side of a rail 12 so as to be integrated, and these transceivers can be easily installed by collectively performing overall adjustment and confirmation at the job site. In addition, with commonly using the transmitter 33 placed in the midst of the receivers 27, 29, the number of transmitters can be made less than the number of receives, and even in that case, since the number of pairs of the transceiver and the receiver same as the number of receives is configured, the number of facility members, consequently, the material cost and the processing cost can be saved.SELECTED DRAWING: Figure 1

    【課題】現場への設置が容易な車輪検出器を実現する。【解決手段】空中伝搬信号を送信する送信器33と、その空中伝搬信号を受信する受信器27,29と、それらの受信器の受信状態の良否に応じて車輪11の有無を判別する判定部31とを備えた車輪検出器30において、レール12の片側に取り付けられる一の保持部材34に送受信器27,29,33を取り付けて一体化しておくことにより、送受信器の相互関係や信号レベル等に係る調整を予め工場や検査室などで済ませておくことが可能になり、現場では全体的な調整や確認を纏めて行うことで容易に設置できる。また、送信器33を受信器27,29の中間に置いて共用させることにより、送信器の個数を受信器の個数より少なくすることが出来、それでも受信器の個数と同じ個数の送受信器対が構成されるので、設備部材数の削減ひいては材料費および工費の節約を図ることができる。【選択図】 図1
