物镜驱动装置及其制造方法
摘要：
本发明提供物镜驱动装置及其制造方法。物镜驱动装置构成为包括：物镜(13)，其使从光源发出的光束会聚于光盘(11)；和透镜保持架(14)，其保持物镜(13)。透镜保持架(14)具有通过粘接来保持物镜(13)的第一粘接部(14i)和第二粘接部(14j)。通过向第一粘接部(14i)供给第一粘接剂(25)来粘接物镜(13)，在使第一粘接剂(25)发生变形的同时，对物镜(13)的光轴的倾斜度进行调整，然后通过向第二粘接部(14j)供给硬化后的杨氏模量比第一粘接剂(25)大的第二粘接剂(26)，来将物镜(13)固定于透镜保持架(14)。
摘要（英）：

The invention provides an objective lens driving device and a manufacturing method thereof. The objective lens driving device comprises objective lens (13) for focusing a light flux from light source on optical disk (11) and lens holder (14) for holding the objective lens (13). The lens holder (14) has second adhesion part (14j) and first adhesion part (14i) for holding the objective lens (13) by adhesion. The objective lens (13) is adhered by application of first adhesive (25) to the first adhesion part (14i), and the tilt of optical axis of the objective lens (13) is adjusted by deforming the first adhesive (25). Thereafter, the objective lens (13) is fixed to the lens holder (14)by application of second adhesive (26) to the second adhesion part (14j), the second adhesive (26) having a Young's modulus after hardening greater than that of the first adhesive (25).
