The invention relates to the field of inflating valves, in particular to a valve cap, an inflating valve structure, a tire and a vehicle. The valve cap comprises a main body structure, a push rod structure, an elastic reset part and a push rod fixing base, wherein a central cavity which is vertically through along the central axis is formed in the main body structure; the push rod structure is arranged in the central cavity and can slide along the central cavity vertically, the upper end of the push rod structure seals the upper port of the central cavity, and the lower end of the push rod structure is located in an inner cavity of the push rod fixing base; the elastic reset part is arranged between the upper end of the push rod structure and the push rod fixing base; the push rod fixing base is located at the lower part of the central cavity, the middle of the inner cavity of the push rod fixing base is in a shape of a trumpet from top to bottom, and a push rod sealing part is arranged at the bottom of the push rod structure and propped on an inner oblique surface of the middle of the inner cavity of the push rod fixing base in a non-inflated state. Sealing in a non-inflated state can be realized, accumulation of dust on the push rod fixing base is prevented, and dust accumulation is avoided.
