PROBLEM TO BE SOLVED: To eliminate possibility of which a light transmission member come off even if an area in which the light transmission member faces on a push operation face becomes large and ensure positioning of the light transmission member by forming a filing guide face on both sides internal of a main body and providing a protrusion at either one of the filing guide face and the guide face, then forming an engagement hole with which the protrusion engages at the other. SOLUTION: On both sides internal part of a main body 20 of a push operation button 2, filing guide faces 22 parallel to each other are formed, and an engagement hole 23 is recessed on the filling guide face 22. An opening 21 is pinched, and fixed protrusions are formed at four top and bottom parts. On a filling guide face 32, each of protrusions 33 protruded to the outside is formed, when a translucent member 3 is engaged to a complete position (filling complete position) as designed the protrusion 22 is engaged with the engagement hole 23. Thus, since positioning of the translucent member 3 is certainly performed at the filling complete position, in case that an opening area of the opening 21 becomes large, the translucent member 3 does not come off from the main body 20 even if push operation force is acted to the member 3. |
