The illustrated elastic boot for sealing according to the first embodiment of the present invention is a boot having a steering shaft 10 penetrating through a hole in the partition wall 11 and having elasticity suitable for sealing therebetween. The boot 1 has a press-fit portion 2 for press-fitting (fixing) the shaft, the hole diameter of which is smaller than the outer diameter of the shaft 10, and a steel intermediate cylinder 2a in an elastic body for maintaining a proper press-fit state. Is buried. There is a separation portion which is separated from the press-fit portion 2 in the axial direction and further separated in the radial direction so as not to interfere with the shaft due to vibration input, and a seal portion is continuously formed therefrom. The seal portion has a seal bulging portion 9 that extends radially outward beyond the partition wall hole, and the surface that contacts the partition wall 11 (dash panel) is the close contact portion 3. As the pressure-contacting action portion 4 for pressing the close contact portion against the partition wall, a pressure-contacting portion 4 having a hook-shaped locking portion 6 projecting from an annular plate 5 in contact with the seal bulging portion 9 is used. It penetrates the protrusion and is locked in the hole of the partition wall 11.
