PURPOSE:To increase the bonding strength of convexed slots by providing a special convexed slot to a prescribed bonding part of a lens barrel of an objective lens and providing a convexed slot also to a part opposed to the convexed slot of an actuator and packing an adhesives in both the convexed slots. CONSTITUTION:The convexed slot 7 is provided to a required bonding face of the lens barrel 1, the convexed slot 8 is provided to a required bonding face of the actuator so as to be opposed to the convexed slot 7 to form pairs. Further, the adhesives 4 is injected to the bonding face between the lens barrel 1 of the objective lens and the actuator 2 similarly as a conventional system and in this case, the adhesive is packed in both the convexed slots 7, 8 and other constitution is similar to that of a conventional system. The concaved slots can be a form of a series of rings or dotted while being cut on the way and the number and the shape are not always limited. |
