Abstract

The mounting fixture of the present invention is used for mounting a ring-shaped elastic seal member between a ring-shaped side surface of an optical component and a holder which holds the optical component. The mounting fixture of the present invention has a first abutting surface which can abut against a top surface of the optical component which intersects the side surface, a projecting part which is arranged so as to surround the first abutting surface and which projects out from the first abutting surface in a direction vertical to the first abutting surface, and a second abutting surface which is provided at the front end of the projecting part and can abut against the elastic seal member.

First claim

1 . A mounting fixture used for mounting a ring-shaped elastic seal member between a ring-shaped side surface of an optical component and a holder which holds said optical component, comprising
a first abutting surface which can abut against a top surface of said optical component which intersects said side surface, a projecting part which is arranged so as to surround said first abutting surface and projects out from said first abutting surface in a direction vertical to said first abutting surface, and a second abutting surface which is provided at a front end of said projecting part and can abut against said elastic seal member.

2 . The mounting fixture according to claim 1 , wherein
said projecting part has a projecting height smaller than a height of said side surface of said optical component.

3 . The mounting fixture according to claim 1 , further comprising a positioning part which is arranged so as to surround said second abutting surface and can abut against said holder, wherein
said positioning part determines a mounting position of said elastic seal member in a height direction of said side surface by abutting against said holder.

4 . The mounting fixture according to claim 1 , wherein
said projecting part comprises a plurality of parts which are arranged apart from each other so as to surround said first abutting surface.

5 . The mounting fixture according to claim 1 , wherein
said mounting fixture includes two surfaces which face opposite directions from each other, and each of said two surfaces is provided with said first abutting surface, said projecting part, and said second abutting surface.

6 . The mounting fixture according to claim 3 , wherein
said positioning part projects out from said second abutting surface in a direction vertical to said second abutting surface, said second abutting surface can further abut against a top surface of another optical component which is larger than said optical component, and a front end of said positioning part in a projecting direction can further abut against another elastic seal member for said other optical component.

7 . The mounting fixture according to claim 1 , having the form of a polygon, wherein
each of at least two surfaces of said polygon is provided with said first abutting surface, said projecting part, and said second abutting surface.

8 . The mounting fixture according to claim 1 , wherein
said projecting part has a plurality of cutaway parts which are arranged apart from each other so as to surround said first abutting surface, and said a plurality of cutaway parts are used for detaching said optical component which contacts said top surface of said first abutting surface.

9 . The mounting fixture according to claim 1 , wherein
said elastic seal member is an O-ring.
