PURPOSE:To prevent the deformation of the top part on the upper edge side of a bellows part by annularly forming the concaved part having a nearly equal wall- thickness at the near center part of the top part of the bellows part in which a plurality of annular top parts and valley parts are formed alternately into multistage form. CONSTITUTION:A shift-lever boot 2 which has a section in square form and is made of the elastic material such as rubber is formed so that a plurality of annular top parts 4 and valley parts 5 are formed alternately into multistage form on the peripheral side, and a bellows part 3 is constituted. A concaved part 6 having a nearly equal wall-thickness is formed annularly at the near center part of the bellows part 3, and a reinforcing rib 7 is constituted on the back side of the top part 4. Therefore, when the shift lever 1 is operated toward retreat stage, the front edge of the top part 4 can be certainly prevented from the total deformation. |
