PROBLEM TO BE SOLVED: To eliminate the need of holding a magnifier by a hand and to make performable a minute work by both hands by making the magnifier easily fixable. SOLUTION: In a lens part 1, a lens 3 is mounted on a lens mount frame 2. A handle part to hold the lens part 1 is constituted of a 1st handle part 4 and a 2nd handle part 5, and the 2nd handle part 5 is formed integrally with the frame 2. A coupling shaft 6 is provided at the end of the 2nd handle part 5, and a coupling hole 7 for the shaft 6 is provided at the end of the 1st handle part 4. By inserting the shaft 6 of the 2nd handle part 5 in the hole 7 of the 1st handle part 4, the handle part of the magnifier is constituted, and the 2nd handle part 5 is held to be turnable with respect to the 1st handle part 4. A magnet 9 is provided on one side surface of a handle part main body 8 on the 1st handle part 4. Therefore, the magnifier is fixed at an optional position by attracting the magnet 9 of the 1st handle part 4 to a steel box, for example, by magnetic force.
