[ An elastic piece 137a elastically supported by a fixing member 137 is provided on the surface of the fixing member 137 facing the reinforcing plate 136a and the reinforcing plate 136a is provided with the elastic piece 137a. And a fixing protrusion 137b to be inserted into the fixing groove 136c is provided.

Hereinafter, an assembling structure of the grip type locking device for a sliding window according to the present embodiment will be described.

In the drawings, FIG. 14 is a front sectional view of FIG. 12, and FIG. 15 is a sectional view taken along the line A-A 'of FIG.

14 and 15, the rotation shaft 132a of the rotation shaft member 136 is inserted into the through hole 132d formed in the outer wall 132c of the grip body portion 132, and the rotation shaft 132a of the rotation shaft member 136 is inserted into the through- The reinforcing plate 136a integrally provided at the rear end is in close contact with the inner surface of the outer wall 132c.

The fixing member 137 is inserted into the gap between the reinforcing plate 136a and the partition wall 132b to fix the assembly position of the rotation shaft 132a. At this time, as the fixing protrusion 137b provided on the elastic piece 137a of the fixing member 137 is inserted into the fixing groove 136c of the reinforcing plate 136a, the insertion position of the fixing member 137 is fixed, It is possible to prevent the fixing member 137 from being arbitrarily separated by the impact generated in the process of opening and closing the window frame.

The plurality of insertion pins 136b provided on the reinforcing plate 136a of the rotary shaft member 136 are respectively inserted and supported in the insertion holes 132e formed in the outer wall 132c, The engagement force of the grip body portion 132 is increased. Therefore, in the process of repeatedly rotating the grip main body portion 132 for opening and closing the window frame, it is possible to prevent the occurrence of clearance at the assembled portion of the grip main body portion 132 and the rotation shaft member 136, It is possible to prevent the joint portion from being damaged by the load applied to the joint portion of the shaft member 136 and the grip body portion 132. [

The rotary shaft member 136 is formed of a metal material such that the rotary shaft member 136 is relatively in contact with the grip body portion 132 And is provided with excellent rigidity. Therefore, it is possible to prevent the rotating shaft 132a from being damaged or deformed by the load concentrated on the rotating shaft 132a in the process of repeatedly opening and closing the window frame by pulling or pushing the grip portion 130. [

On the other hand, when the elastic piece 137a of the fixing member 137 is pressed by using a separate tool, the fixing protrusion 137b provided on the elastic piece 137a is separated from the fixing groove 136c of the reinforcing plate 136a In this state, the fixing member 137 inserted between the reinforcing plate 136a and the partition wall 132b can be pulled and separated from the grip main body portion 132. Since the rotary shaft member 136 can be separated from the grip body portion 132 when the fixing member 137 is separated as described above, the rotation shaft member 136 can be easily replaced.
