Abstract
A securing device, for securing a light interception frame made of a resilient material to an end face of a lens frame, includes engagement projections and engagement surfaces provided on the peripheral surface of the lens frame, engagement legs and engagement pieces provided on the light interception frame having a light interception plate portion; wherein the light interception plate portion has an opening through which light can pass. The positional relationship between the plurality of engagement projections and the plurality of engagement legs, and the positional relationship between the plurality of engagement surfaces and the plurality of engagement pieces are such that when the engagement pieces engage with the engagement surfaces in a free state of the light interception frame, no engagement occurs, and the engagement legs are engaged by the engagement projections by elastically deforming the light interception frame.
