The ball seat 330 is formed in a shape that surrounds the ball portion 305 and a protrusion 335 is formed at an end of the opening end portion 331 to protrude toward the ball portion 305, And supports the ball portion 305. The protrusion portion 3350 prevents the ball portion 305 from being detached from the ball seat 330. [

That is, the ball portion 330 is supported by the protrusion 335 formed on the ball seat 330 to prevent the ball seat 330 from being separated from the ball housing 330. The ball seat 330 is inserted into the ball housing 310, The ball portion 305 and the ball seat 330 can be stably coupled to the ball housing 310 and the cap is coupled to the ball housing 310 and the ball housing 310 ) Is prevented from being damaged or corroded due to roll-cocking.

The support member 350 is formed in a hollow tube shape having a large diameter portion and a small diameter portion 353 and a small diameter portion 351 so that the small diameter portion 351 is inserted into the upper end portion of the ball housing 310 And the end of the small diameter portion 351 supports the opening end 331 of the ball seat 330.

Also, the large-diameter portion 353 has an outer circumferential surface formed to be angled so that a tool such as a spanner or a wrench can be engaged. In assembling, the support member 350 can be rotated using a tool, thereby facilitating assembly.

The small diameter portion 351 is inserted into the upper end of the ball housing 310 to support the ball seat 330. As shown in Figure 3, The small diameter portion 351 can be screwed into the coupling portion 311 so that the depth of insertion of the small diameter portion 351 into the ball housing 310 can be adjusted.

The degree of compression of the ball seat 330 according to the depth of the small diameter portion 351 inserted into the ball housing 310 is adjusted and the rigidity of the ball seat 330 is increased as the ball seat 330 is compressed.

4 to 6, the engaging portion 311 is stepped on the inner circumferential surface of the ball housing 310 and is enlarged in diameter, and the small step portion 413 of the engaging portion 311 is formed with a small- And the end of the first arm 351 may be supported.

The end of the small diameter portion 351 is supported by the step portion 413 to prevent contact with the ball portion 305.

The small end portion of the small diameter portion 351 protrudes to the inside of the ball seat 330 to support the opening end portion 331 of the ball seat 330 to prevent the ball seat 330 from coming off, The collision between the ball portion 305 and the outer circumferential surface is prevented.

As the tapered portion 355 is formed on the inner circumferential surface of the support member 350, the ball stud 303 is inclined from the ball housing 310 to rotate the ball portion 305, 350 are prevented from colliding with each other.

The small diameter portion 351 is inserted into the ball housing 310 as the outer circumferential surface thereof is screwed to the coupling portion 311 and the small diameter portion 351 is inserted into the ball housing 310, The small end portion of the small diameter portion 351 supports the opening end portion 331 of the ball seat 330 while compressing the ball seat 330 by the depth of the engagement portion 311.

6 (b), the small diameter portion 351 is screwed to the coupling portion 311. When the small diameter portion 351 is coupled until the small diameter portion 351 is supported by the step portion 413, The compressed ball sheet 330 is compressed in the same direction as that of the ball seat 330 of FIG. 6A as the end portion of the compressed ball sheet 330 compresses the opening end portion 331 of the ball seat 330 by the depth of the coupling portion 311 Since it is in the compressed state, the rigidity is relatively large.

As the end of the small diameter portion 351 supports the ball seat 330 and compresses the ball seat 330, the ball seat 330 rotates in the direction of the ball portion 305 to cover the ball portion 330, The ball seat 330 is compressed between the ball housing 310 and the ball portion 305 to have a large rigidity because the opposite side of the opening end portion 331 of the ball housing 330 is supported by the ball housing.

At this time, as the ball seat 330 formed of elastic material is compressed, the elasticity becomes smaller and the rigidity becomes larger. As a result, an impact is generated in the ball portion 305, and the impact is absorbed while compressing the ball seat 330. However, The large ball seat 330 absorbs the impact and is compressed to a small extent, thereby improving durability.

The small size portion 351 of the support member 350 is inserted into the engaging portion 311 of the ball housing 310 so that the rigidity of the ball seat 330 can be adjusted according to the type of the vehicle, So that the rigidity of the ball seat 330 can be adjusted by adjusting the degree of compression of the ball seat 330 by the end of the small diameter portion 351. [

Another example in which the ball seat 330 is compressed and its rigidity is adjusted according to the depth at which the support member 350 is inserted into the ball housing 310 and the support member 350 is press-fitted into the ball housing 310 The rigidity of the ball seat 330 can be adjusted, which may be difficult to precisely adjust in adjusting the depth at which the support member 350 is press-fit into the ball housing 310.

7, an engaging portion 311 having an engaging groove 715 formed at an upper end of the ball housing 310 is provided and the end of the small diameter portion 351 of the supporting member 350 A coupling protrusion 755 protruding outward and coupled to the coupling groove 715 is formed.

The coupling protrusion 755 is formed at the end of the small diameter portion 351 and is elastically deformed as the support member 350 is pressed into the ball housing 310 and inserted into the coupling groove 715. Therefore, So that the end of the ball seat 330 can be supported.

At least one of the engaging grooves 715 may be formed and at least one of the engaging grooves 715 may be formed so that the engaging protrusion 755 may be inserted into the ball housing 310 while the supporting member 350 is inserted into the ball housing 310, The depth of the support member 350 pressed into the ball housing 310 becomes deeper as it is coupled to the coupling groove 715 and the ball seat 330 is also gradually compressed so that the rigidity of the ball seat 330 can be controlled.

When the support member 350 is pushed into the ball housing 310 and the small diameter portion 351 moves downward, the coupling protrusion 755 coupled to the coupling groove 715 can be easily moved downward The end surface of the groove 715 is provided with an inclined surface 715a formed to be inclined downward.
The coupling groove 715 is provided with a flat support surface 715b to prevent the coupling protrusion 755 coupled to the coupling groove 715 from being separated from the upper side.
That is, the engaging groove 715 is composed of the inclined surface 715a and the supporting surface 715b so that the engaging projection 755 is moved downward along the inclined surface 715a to be engaged with the engaging groove 715, The coupling protrusion 755 is supported on the support surface 715b to prevent the coupling protrusion 755 from being separated upward.

The support member 350 has a small diameter portion 351 which is screwed to the coupling portion 311 of the ball housing 310 and is inserted into the coupling portion 311 in accordance with the depth of the small diameter portion 351, As the insertion amount of the small diameter portion 351 is increased, the ball seat 330 is compressed and the rigidity is increased. As the insertion amount of the small diameter portion 351 is smaller, the ball seat 330 is decompressed and the rigidity becomes smaller.

According to the embodiments of the present invention having such a shape and structure, the stiffness of the ball seat required can be adjusted according to the type of the vehicle, so that the durability of the ball seat can be improved and the shock absorption can be smoothly performed, And the steering feeling of the driver is improved.

In addition, there is an effect that a ball portion can be provided inside the ball housing while preventing a ball housing from being broken or corroded by a supporting member being coupled to the ball housing.
