Combination gear, lens adjusting mechanism and electronic equipment

Abstract

Paired first gear (11) and second gear (12) provided with identical tooth profiles and combined so as to be rotatable with their rotational centers laid in agreement with each other. One of the paired gears (11,12) is provided with an elastic displacement part (15) capable of urging in the direction in which the other gear is rotated against the one gear. The other gear is provided with a positioning section (21) for locating the other gear against the one gear, and the elastic displacement part (15) abuts on the positioning section (21).
本发明包括具有相同的齿廓并在齿轮的旋转中心重合的状态下可旋转地组合的一对第一齿轮(11)和第二齿轮(12)。该对齿轮(11)和(12)中的一个齿轮形成有在另一个齿轮相对于所述一个齿轮旋转的方向上被偏置的弹性位移部(15)。所述另一个齿轮形成为具有相对于所述一个齿轮来定位所述另一个齿轮的定位部(21),且弹性位移部(15)接触该定位部(21)。
