Abstract

PURPOSE:To improve durability in a stopper pin, by making up the length of the stopper pin used in a turning regulating device, which regulates such a turn as being more than the specified range of a turning braket of a tilt wheel device, to be a size more than the width of the turning braket. CONSTITUTION:Inserting an intermediate shaft into the inside of a fixed braket 101 locked to a car body, an upper shaft being coupled with a steering wheel is coupled to an upper end of the intermediate shaft via a universal joint and rotatably supported on the fixed bracket 101 free of rotation. With this constitution, such a turning motion as more than the specified range of the turning bracket 102 is thus regulated owing to a stoper pin 102d installed in the turning bracket 102 and a stopper hole 101c made up in the fixed bracket 101. In this case, the stopper pin 102d makes its length a size larger than a distance between leg parts 102R and 102L of the turning bracket 102 and further makes each leg part support both ends of its own.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a tilt handle device for a vehicle that can adjust a wheel handle to a position where the driver's body is relaxed.

(Prior Art) Conventionally, such a tilt steering wheel device for a vehicle is
There was something like the one shown in Figures 1 to 7 (Jetkan Showa 51-2
No. 8901). In FIG. 1, "Otsu 11" is a lower shaft whose one end is connected to a steering gear (not shown).One end of an intermediate shaft 12 is connected to the other end of this lower shaft 11, and the other end of this lower shaft 11 is connected to a steering gear (not shown). The end is connected to the upper shaft 13 via the universal joint 14.
A steering handle 17 is fixed to the other end of the upper shaft 13 . The intermediate shaft 12 is surrounded by a second column tube 22.

It is surrounded and fixedly supported by a fixing bracket 31 fixed to the vehicle body. A portion of the fixing bracket 31 that intersects with a tilt axis that passes through the joint center of the universal joint 14, that is, the spherical center of the universal joint as a spherical kinematic chain of mechanisms and extends in the approximately horizontal vehicle width direction, has a coaxial line. Connecting means 50,60 are provided having
．． 60 connects the leg portions 32R132I7 on both sides of the rotation bracket 320 so as to be rotatable about the tilt axis. The upper shaft 1 is located on the center axis of the rotation bracket 32.
3 is rotatably supported, and the upper shaft 13 and the pivot bracket 32 are connected to the bolts 51.6 of the coupling means 50.60.
Both can be rotated around 1.

In such a conventional tilt steering wheel device for a vehicle, when the rotating bracket 32 is rotated by operating the manual lever 44, the steering handle 17 is also rotated, and the steering handle 17 is adjusted to a height that suits the physique of the driver. It is locked by the fixing device 40 at the position.

(Object of the Invention) However, in the conventional vehicle tilt nodle device, as shown in FIG.

It is inserted into a long hole 31c formed in 1 and is engaged alternately with both ends thereof. Further, as shown in FIG. 5, a shock absorbing material 32e is attached to the free end of the stopper bolt 32d. As described above, since the stopper bolt 32d has a cantilever support structure, the impact force when the rotation bracket 32 rotates and the stopper bolt 32d abuts the end of the elongated hole 31c of the fixed bracket 31 is reduced. Therefore, there is a problem that the stopper pole l-32d may be damaged despite the shock absorbing material 32e.

Therefore, an object of the present invention is to improve the durability of the constituent members of the rotation regulating means against the i-stain impact force.

(Structure of the Invention) A tilt steering wheel device for a vehicle according to the present invention includes an intermediate shaft whose one end is connected to a steering gear via a lower shaft, and whose one end is connected to the other end of the intermediate shaft via a universal joint. an upper shaft with a steering handle fixed to the other end;
a fixed bracket that surrounds the intermediate shaft and is fixed to the vehicle body; The rotating bracket has a rotating bracket having legs on both sides connected to the fixed bracket, a stopper pin supported by the rotating bracket, and a stopper hole formed in the fixed bracket into which the stopper pin is inserted. A tilt steering wheel device for a vehicle is provided with a rotation regulating means for regulating rotation beyond a predetermined value. Both ends of the holder are supported by the legs on both sides, respectively.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. FIG. 8 is a diagram showing a first embodiment of the vehicle tilt handle device according to the present invention.

In FIG. 8, reference numeral 101 denotes a fixing bracket that surrounds an intermediate shaft and a column tube (not shown) and is fixed to the vehicle body. Part 1
Equipped with 01L.

Further, on both sides of the fixed bracket 101, long holes 101C are formed into which a stopper pole l-]02d, which will be described later, is inserted. 102 is a rotating bracket having leg parts 102R1102L on both sides, and these leg parts 102R, I
(In the middle part of 12L, there is a fixed bracket I/1 (1
Connecting holes 102a, 102b coaxially connected to the connecting holes 101a, 101b of No. 1 through connecting means (not shown)
is formed. In this case, the leg portions 102R2102L of the rotating bracket 102 are connected to the outside of the arm portions 101R, lot L of the fixed bracket 101.

There are stopper bolt holes 102e and 102f at the tips of the arm parts 102R and 1021, and the stopper bolt holes 102e and 102f and the elongated hole 101 inside the stopper bolt holes 102e and 102f.
A stopper bolt 102d passes through C and is fixed by a NAND 98. By alternately abutting both ends of the elongated hole 101c, the rotation bracket 102 moves within the range of the fixed bracket 101.
