とする車両用無線式解錠装置。[Claims for Utility Model Registration] 1. Transmission request code transmitting means that transmits a transmission request code consisting of a combination of on and off radio waves by a predetermined activation operation, and collating the received key code with a pre-registered key code. and a key code verification means that outputs an unlock signal when the two match, and a vehicle-side transceiver that switches from an intermittent reception standby state to a continuous reception state when receiving radio waves from the vehicle-side transceiver. It has a receiving state switching means, and a key code transmitting means that collates the received transmission request code with a pre-registered transmission request code, and when the two match, transmits the above-mentioned key code consisting of a combination of turning on and off radio waves. A wireless vehicle unlocking device comprising: a mobile transceiver, wherein the vehicle transceiver is configured to intermittent the mobile transceiver prior to transmitting the transmission request code in conjunction with the predetermined activation operation; A wireless unlocking device for a vehicle, comprising a first continuous transmitting means that continuously transmits radio waves for a period longer than a reception standby period. 2 A transmission request code transmitting means that transmits a transmission request code consisting of a combination of on and off radio waves by a predetermined activation operation, and the received key code is compared with a pre-registered key code and unlocked when the two match. a vehicle-side transceiver having a key code verification means for outputting a signal; and a reception state switching means for switching from an intermittent reception standby state to a continuous reception state when receiving a radio wave from the vehicle-side transceiver; A mobile transceiver comprising: a key code transmitting means for comparing a transmission request code with a pre-registered transmission request code and transmitting the key code consisting of a combination of on/off radio waves when the two match; In the wireless unlocking device for mobile phones, the vehicle-side transceiver, in conjunction with the predetermined activation operation, transmits the transmission request code for a period longer than the intermittent reception standby cycle of the mobile transceiver. If communication is not established between the first continuous transmitting means that continuously transmits radio waves by using the first continuous transmitting means and the portable transceiver within a predetermined time after the transmission by the first continuous transmitting means, the portable transceiver 1. A wireless vehicle unlocking device comprising: second continuous transmission means for continuously transmitting radio waves for a period longer than twice the intermittent reception standby period.
