PURPOSE:To prevent a glare cutting cap from dropping by providing a folded portion by extension of one end of a coil spring mounted on one end of the glare cutting cap, and inserting the folded portion into a hole provided near the front side of a cylindrical body. CONSTITUTION:To mount a glare cutting cap 1, the folded portion 6 of a coil spring 5 is inserted into the hole 7 of a cylindrical body 3 and then the end portion of the cap 1 on which the spring 5 is mounted is inserted into a mounting hole 4 against the resiliency of the spring 5. Next, the end portion of the cap 1 on which the spring 5 is not mounted is inserted into another mounting hole. To remove the cap 1, the end portion on which the spring 5 is not mounted is pressed downward against the resiliency of the spring 5 and removed from the mounting hole 4 and then the end portion on which the spring 5 is mounted is removed from the mounting hole 4. Because the folded portion 6 of the spring 5 is hooked to the hole 7, the cap 1 can be prevented from dropping. Therefore, a cross folded portion 6 can be further effective. |
