合つていて、ピニオンの回動により作動ロツド３
が軸方向に摺動作動するようになつている。 In FIG. 1, a gearbox 2 is attached to a frame 1 of a vehicle body. The pinion support 2a of the gearbox 2 supports a pinion (not shown) that rotates when a steering wheel (not shown) is rotated, and the operation rod support 2b of the gearbox 2 supports an actuation rod 3. is inserted so that it can slide freely. The actuating rod 3 has rack teeth cut into it, which mesh with the pinion, and rotation of the pinion causes the actuating rod 3 to move.
is adapted to slide in the axial direction.

介して左右の車輪の転舵が行われる。 The actuating rod 3 protrudes from the gearbox 2 on both sides, and one arm 5a of a center lever 5, which is rotatably attached to a pivot shaft 4 on the center line of the vehicle body, is pivotally attached to one end 3a. There is. Further, left and right tie rods 6 and 7 for controlling the direction of the left and right wheels are pivotally connected to the other arm 5b of the center lever 5. Accordingly, the axial movement of the actuating rod 3 causes the center lever 5 to rotate, and the left and right wheels are steered via the tie rods 6 and 7.

ギヤボツクス２の内に塵埃や雨水などが入らない
ようにしてある。 As shown in FIGS. 2 and 3, the end 3b of the actuating rod 3 that does not connect the center lever 5 protrudes from the actuating rod support 2b of the gearbox 2, and the end 3b of the actuating rod 3 that does not connect the center lever 5 is connected to the end 2c of the actuating rod 2b. The boot 8 is stretched between the end 3b of the actuating rod 3,
It is designed to prevent dust and rainwater from entering the gearbox 2.
本考案はブーツ８の構造に係わるものであつ

の端縁８ｄは、作動ロツド３の端部３ｂにクリツ
プ１０で止着してある。 The present invention relates to the structure of the boot 8, and the bellows portion of the boot 8 has a large inner and outer diameter.
A and a bellows part 8b having a small inner and outer diameter, which are coaxial with the bellows part 8b, are continuously formed. The end edge 8c of the bellows part 8a with a large inner and outer diameter is fixed to the end part 2c of the operating rod support part 2b of the gearbox 2 with a clip 9.
The end edge 8d is fixed to the end 3b of the actuating rod 3 with a clip 10.
このブーツ８は、いいかえると一方の蛇腹部の
山（外径部）と他方の蛇腹部の山、一方の谷（内
径部）と他方の谷、また一方の山と他方の谷のそ
れぞれの径が異なるようにして、同一径となるの
を避けるように形成してある。 In other words, the boots 8 have the diameters of the ridges of one bellows part (outer diameter part) and the ridges of the other bellows part, one valley (inner diameter part) and the other valley, and the diameters of one peak and the other valley. They are formed to have different diameters to avoid having the same diameter.
従つて第３図に示すように蛇腹部を密着させた
とき、内外径の大きい蛇腹部８ａと内外径の小さ
い蛇腹部８ｂとの連続部分において、内外径の大
きい蛇腹部８ａの内に、内外径の小さい蛇腹部８

短かくなる。またこれに関連して作動ロツド３の
突出する長さｆを短かくすることができるから、
設計に際してこの部分を小さくまとめることがで
きるという特長がある。 Therefore, when the bellows parts are brought into close contact with each other as shown in FIG. Small diameter bellows part 8
Since b begins to enter, the length e when in close contact becomes shorter. In addition, in connection with this, the protruding length f of the actuating rod 3 can be shortened.
The advantage is that this part can be made smaller when designing.
