Abstract: A vehicle inflation device includes a hollow body having a front opening formed in a front end thereof and adapted for connecting with a vehicle exhaust pipe. Two corresponding through-holes are disposed in the hollow body for installation of an atmospheric relief valve. A guiding pipe is disposed on a rear end of the hollow body, and a check valve is disposed in the guiding pipe. The guiding pipe is engaged with an end of a flexible rubber pipe, and a gas nipple connector is disposed on another end of the flexible rubber pipe for engaging with a tire gas nipple. The vehicle inflation device further includes a retractable pipe assembly. An end of the retractable pipe assembly is hooked to a steering wheel, and another end of the retractable pipe assembly is pressed against an accelerator pedal for maintaining gas exhaustion to achieve inflation of a tire.
