英 ['ræt(ə)ltræp] 美['wɛntl,træp]

rattletrap: 1766, originally a noun, "knick-knacks, trifles, odds and ends," from rattle (adj.) + trap, perhaps in the sense in traps (n.2). Hence, "a shabby, rattling object," especially a rickety coach or other vehicle (1822). The adjectival sense of "rickety" is recorded from 1834.
