It is maintained in the fixed state (31), the guide rail 31 of the holder member 3 and the guide rail 41 of the coupling member 4, the central axis (61, 61 ') of the housing (6) This space is fitted The.

The elastic member 5 is a means for causing the actuator 7 to have an elastic force so that the actuator 7 fixedly coupled to the holder device 2 is moved forward, backward or restored to its original position. By using a material such as a spring having excellent restoring force to its original state even when contracted or expanded, and the elastic member 5 is fixed to the guide rail 31 of the holder member 3 in a compressed state than the guide rail 31. It is formed long.

And, both ends of the elastic member 5, the support member 51 is fixedly coupled, when the elastic member 5 is inserted into the guide rail 31 of the holder member 3, the elastic member 5 The support members 51 fixedly coupled to both ends of the support member 51 have a state in which each inner surface of the guide rail 31 opening 33 of the holder member 3 and the guide rail 41 of the coupling member 4 is supported. It becomes a state built in the said holder apparatus 2 in a more stable state.

The assembly process and operation state of the holder device of the zoom switch formed as described above are as follows.

First, the holder member 3 is inserted into the elastic member 5 through the guide rail 31 inlet 32 formed in the holder member 3 and presses the elastic member 5 with the coupling member 4. By inserting the engaging member 4 into the engaging groove 34 of the 3, the holder device 2 for fixing the actuator 7 to the housing 6 is easily assembled, and the holder device 2 The overall shape of) has a simple structure in the form of a flat plate.

In this case, the inner groove coupling portion 42 of the coupling member 4 is inserted into the inner groove 35 of the coupling member 34 of the holder member 3, and the outer groove 36 of the coupling groove 34 is inserted therein. As the outer groove coupling portion 43 of the coupling member 4 is inserted, the projection 36 'formed in the outer groove 36 is inserted into the groove 42' of the inner groove coupling portion 42. Inserted, the holder member 3 and the coupling member 4 will maintain a more structurally robust state.

The opening 33 of the guide rail 31 of the holder member 3 is formed to have a width smaller than the diameter of the elastic member 5 and is fixed to the other end of the elastic member 5. The support rail 41 of the coupling member 4 is also formed to have a width smaller than the diameter of the elastic member 5 to support the support member 51 fixed to one end of the elastic member 5. Thus, the elastic member 5 formed longer than the guide rail 31 of the holder member 3 is in a state of being embedded in the holder device 2 in a compressed state.

When the holder device 2 is assembled as described above, the actuator 7 is inserted into each of the fixing protrusions 71 of the actuator 7 in the pair of guide holes 63 formed in the housing 6. And the central shafts 61 and 61 'protruding from the lower surface of the housing 6, respectively, after the fixing to the seating groove 62 of the housing 6, respectively, the holder member 3 of the holder device 2; While being positioned to be inserted into the opening portion 33 and the guide rail 41 of the coupling member 4, the fixing projection protruding to the lower surface of the housing 6 through the guide hole 63 of the housing (6) 71 is inserted into the through hole 37 of the holder member 3, and then the fixing protrusion 71 protruding to the lower portion of the holder device 2 through the through hole 37 by a method such as heat welding.
