PURPOSE: To automatically adjust a crown by making the crown movable in the transversal direction and rotatable against a main body so that the crown is hardly tilted against the main body. CONSTITUTION: A crown 41 is fitted to a main body 21 through the clearance between the upper and lower end faces of the crown 41. Four fitting wires 51 are used for fixing the crown 41 to the main body 21. The upper ends of the wires 51 are fitted to the crown 41 and the lower ends of the wires 51 are fitted to the main body 21. The main body 21 is fixed to a vertical supporting member 14 so that the main body 21 can be moved together with the member 14. In addition, the crown 41 has a socket for housing an element. In such a way, the crown 41 is made movable in the transversal direction and rotatable by using the wires 51 and providing the clearance between the crown 41 and the main body 21 and, at the same time, is prevented from tilting. Therefore, the position of the crown 41 can be adjusted automatically in the transversal direction while a surface mounted device is maintained in parallel with the socket. |
