Abstract: When a luggage floor moves forward of the vehicle by an external force from the rear of the vehicle, a front surface portion of the luggage floor strikes left and right rear side leg portions of a rear suspension member to avoid applying an input load to the canister. The canister is disposed at nearly the same position as the left and right rear side leg portions of the rear suspension member or at a position more forward than that position.

Abstract: There is provided a method for obtaining an alkyladamantyl ester efficiently by distilling and purifying a crude alkyladamantyl ester containing impurities which decompose the alkyladamantyl ester without decomposing the alkyladamantyl ester. The crude alkyladamantyl ester such as crude 2-methyl-2-adamantyl methacrylate is distilled in the presence of a heterocyclic compound and/or a basic compound such as 3-ethyl-3-hydroxymethyloxetane or diglycidyl bisphenol A.
