2. Description of the Related Art It is well known that, for example, at the time of assembling a vehicle, a part mounting operation in which mounting parts formed in advance on a part of the vehicle body must be mounted by screwing is performed. It is difficult for the installation worker to directly grasp the mounting screws (bolts, screws, etc.) for screwing the mounting parts that are positioned at predetermined positions on the vehicle body in a production line where the mounting parts must be screwed. Or if it is not possible to support the mounting screws in tight places where it is difficult for the mounting operator to reach, and because the mounting parts must be grasped, It may not be possible to grip the mounting screw with the part.

[0003] As a means for enabling the mounting operation of the mounting part under the mounting operation of the mounting part, a mounting used for mounting the mounting part on a vehicle body or the like at a predetermined position of the mounting part. 2. Description of the Related Art There has been known a temporary holding structure of a mounting screw which is designed so that a screw is temporarily held in advance and a mounting operator can fix the screw without directly grasping the mounting screw.

[0004] For example, as shown in FIG. 4, the tip of the mounting screw 3 is inserted into the mounting screw insertion hole 2 pre-drilled in the mounting part 1, and the insertion position of the mounting screw 3 is temporarily held. For this purpose, for example, when the fixing screw 3 is screwed into the mounting body 5 such as a vehicle body, the temporary bonding force of the adhesive 4 is destroyed, and the fixing screw 3 is screwed into the mounting body 5. 5 or a circumferential groove 6 is formed in the neck of the mounting screw 3 so that the mounting screw 3 is inserted into the mounting screw insertion hole 2 formed in the mounting component 1. After the insertion, the C-ring 7 is engaged in the above-mentioned peripheral groove 6 from the leading end side of the mounting screw 3 to temporarily hold the mounting screw 3 so that the mounting screw 3 is not detached from the mounting component 1. Retaining structures are known. Further, as shown in FIG. 6, there is a type in which the mounting screw 3 is pressed into a thin plate-like washer 30 instead of the C-ring 7 in FIG.
