欠点があ−）だ。(Prior art) Conventionally, in this type of steering device, play has occurred in the reduction mechanism, various pivot parts, and screw cutter parts, and it has been difficult to accurately set the steering wheel to a predetermined tilt angle. The drawback is that it cannot be tilted, it lacks steering stability, and it causes discomfort to the driver.

ける構成としたものである。In order to achieve such an object, the present invention provides a screw nut mechanism that converts power from a rotational drive source from rotational motion to linear motion. and a tilt steering device comprising an upper main shaft in which the upper bracket swings relative to the fixed part due to the linear movement and simultaneously acts as a tilter, wherein a male thread member in the screw nut mechanism and a female thread member located on the outer periphery of the male thread member. A slit or a small gap extending in the radial direction is formed in one of the two, and the outer circumference of the female threaded member or the inside of the male threaded member is biased in a direction that strengthens the contact between the male threaded portion and the female threaded portion. The configuration is such that a suppressing means is provided.

行なう構成としてい−−るためガタ殺しに必要な力が比
較的小ぎくて済む。According to the present invention, the occurrence of backlash can be prevented by only slightly changing the configuration of the conventional screw nut mechanism, thereby eliminating an increase in cost. Since it is configured to kill the rattle, the force required to kill the rattle is relatively small.

果がある。In addition, since the screw nut mechanism eliminates backlash and prevents reversal at the same time, even if play occurs in a part located closer to the rotational drive source than the screw nut mechanism, such as the reducer groove, the steering will be prevented. The effect is that it is not transmitted to the wheels, so there is no need to eliminate rattling in the speed reduction mechanism.
