Therefore, the radial force generated by the first claw 311 pushing against the inner wall surface of the housing 10 can drive the adjusting portion 33 on the first ring portion 31 to push against the outer ring of the bearing 40, and the radial force generated by the second claw 321 pushing against the inner wall surface of the housing 10 can drive the adjusting portion 33 on the second ring portion 32 to push against the outer ring of the bearing 40, so as to improve the adjusting stability of the gap adjusting member 30, ensure that the worm 22 can move towards the worm wheel 21 under the action of the radial force, and effectively reduce the gap between the worm wheel 21 and the worm 22.
It will be appreciated that in some embodiments, the adjustment portion 33 has a smaller diameter of the profile circle than the first and second ring portions 31, 32. Thereby, the urging effect of the adjustment portion 33 on the bearing 40 can be improved, and the first claw 311 and the second claw 321 can provide a more sufficient radial force.
Further, the other end of the regulating portion 33 is at least partially protruded toward the bearing 40 in the radial direction. From this, through the arch that sets up bearing 40, can absorb a certain amount of clearance through the arch towards bearing 40, avoid clearance adjustment piece 30 after the live time overlength, the problem that the regulating effect descends appears, improve regulation stability.
Further, a lightening groove 34 is provided on the first ring part 31 and/or the second ring part 32. Preferably, the lightening groove 34 is provided at a position opposite to the opening of the first ring part 31 and the second ring part 32, so that the working stability of the lash adjuster 30 can be ensured and the lash adjuster 30 can be prevented from being out of order while lightening is achieved.
