るものにも適用し得ることは云うまでもない。As a result, the tightening torque of the nut E in the clockwise direction in the drawing acts on the temporary fixing jig 1, so that the temporary fixing jig 1 that has received this torque has the rightward upward concave portion as shown in FIG. 15 is pulled out from the shaft portion D 6 of the bolt D and is rotated clockwise in the figure to expose the right end below the flange. Therefore, finally, the exposed right end portion is tapped to remove the inward concave portion 16 at the left end from the bolt D, the temporary fixing jig 1 is removed from the flange portion B 2 , and the right bolt D is tightened with the tightening nut E. Tighten and finish all assembly work. The above-described embodiment relates to a temporary fixing jig used for assembling the exhaust pipe A and the exhaust silencer assembly B, but the temporary fixing jig according to the present invention has a large deformation amount like a coil spring. It goes without saying that it can be applied to any device as long as it is used for assembling a loosening prevention mechanism using an elastic member.

とができる。(Effect) As described above, according to the present invention, the temporary fixing jig is provided with the concave portion in the direction orthogonal to the longitudinal direction of the jig, and the other end thereof is oriented in the direction parallel to the longitudinal direction of the jig. Since the concave portion is provided so that the tip end portion of the bolt projecting to the joint surface of one of the assembly members is locked in a state in which the elastic member having a large deformation amount is compressed, the bolt having a different orientation can be used. Can be securely temporarily fixed, and by preliminarily fixing the bolt on one of the assembling members, the assembling work of both assembling members can be performed very easily and efficiently. Moreover, since the tightening force of the nut is used or a force is applied in the direction orthogonal to the longitudinal direction of the jig, the recess provided at one end of the jig can be easily removed from the bolt. The jig can be removed very easily after the assembling of both the assembling members.
