PROBLEM TO BE SOLVED: To store a rubber switch in a holder well and to improve the positioning precision of the rubber switch. SOLUTION: A guide rail 11c having a rigidity in the breadthwise direction is formed on one side of a rubber switch 11 in parallel with the lengthwise direction. A groove 12c to be matched to the guide rail 11c is formed on one side of the outside of a holder 12. The guide rail 11c can be inserted to the groove 12c from above at right angles to the breadthwise direction. A rubber switch 11 is built in the holder 12. The guide rail 11c is successively inserted to the groove 12c from the end part, and the uninserted part of the guide rail 11c is guided to the groove 12c by the inserted part of the guide rail 11c. The rubber switch 11 is positioned to the holder 12 in the breadthwise direction by surfaces facing each other in the breadthwise direction of the groove 12c and the guide rail 11c. |
