1. A vehicular steering device comprising:
a turning shaft movable in a vehicle widthwise direction;
a stopper provided at an end of the turning shaft;
a housing which is extended in the vehicle widthwise direction so as to be able to store the turning shaft therein, has an opening at an end in the vehicle widthwise direction formed in a U-shaped cross-sectional shape and in an annular shape so as to be opened toward the stopper by an external cylinder portion located outwardly in a radial direction, an internal cylinder portion located inwardly in the radial direction, and an annular and flat bottom surface that closes a space between one end of the external cylinder portion and one end of the internal cylinder portion, and has a length from the bottom surface to an open end of the internal cylinder portion shorter than a length from the bottom surface to the open end of the external cylinder portion; and
an elastic body through which the turning shaft passes so as to be movable in the vehicle widthwise direction, and which is formed of an annular integral molding component with elasticity comprising:
an annular first elastic portion having a same length as the length from the bottom surface to the open end of the internal cylinder portion, being fitted in the opening, having a whole surface supported by an inner circumferential surface of the external cylinder portion and the bottom surface, and being provided with a first clearance across a whole circumference from the outer circumferential surfaces of the internal cylinder portion; and
an annular second elastic portion extending toward the stopper from the first elastic portion and being provided with a second clearance across the whole circumference from the inner circumferential surface of the external cylinder portion, the second clearance being larger than the first clearance.
