PURPOSE: Structure for a rubber cushion of a cab mounting part in a truck is provided to relieve impact by moving air into upper and lower air suction parts against impact, and to cut down manufacturing cost by reducing the number of parts. CONSTITUTION: A cab of a truck is fixed by connecting the upper part of a shaft(2) to a hook(3), and an upper plate(4) and a lower plate(5) are fixed by a nut(2a) in the lower part of the shaft. Upper and lower rubber cushions(11,12) are supported by side supporting plates(6) between the upper and lower plates, and air suction parts(13) are symmetrically formed in the contact portion of the upper and lower rubber cushions. A partition member(20) is formed between the upper and lower rubber cushions, and plural holes(21) are inclined in the partition member to flow air between the air suction parts. A drain hole(14) is formed to flow air out of the air suction part in the upper part of the partition member.
