DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in the closing structure of various lids having open / close parts such as lids of various containers or doors of cabinets, and more specifically, A part of the operation piece attached to the inner surface is provided so as to protrude outward from the lid body, and the engaging projection provided on the protruding operation piece is provided inside the lid body. The present invention relates to the provision of a lid closing structure in which the operation piece is bent toward one side so as to elastically engage with the edge of the mounting opening of the lid.

(Prior Art) Conventionally, there have been various methods for closing means such as a lid or a door of this kind according to the respective closing purpose.

For example, in the case of a rear lamp cover of an automobile, the mounting part is in a peculiar situation, and the operating knob of the lamp cover is projected outward while the lamp cover is mounted and closed even though the mounting part vibrates violently. It was required to have a structure that avoids as much as possible.

Therefore, in general, the side edge of the lamp cover is attached to the side of the opening in a laterally open manner, and a clip having an elastically deformable and engaging portion is provided on the upper portion of the lamp cover. In many cases, the elastic deformation of the clip is used to engage and disengage the upper portion of the lamp cover with the upper edge of the opening.

However, in this method, when the lamp cover is removed, the knob portion of the clip is pushed down to disengage the engaging portion of the clip from the opening, and the lamp cover is further opened laterally while maintaining this depressed state. Was required, and removal of the lamp cover was more complicated than expected.

Therefore, as shown in FIG. 9, when the lamp cover 101 is attached to the opening 103 of the trim 102, the lower side of the lamp cover 101 is supported by the lower side of the opening 103, and the lamp cover 1
Attempts have been made to lock the upper edge of the opening 103 using a clip 104 provided on the upper side of 01.

By the way, the conventional example shown in FIG. 9 is a lamp cover.
The upper part of 101 has a recess 101a for accommodating the operation knobs 104a and 104a 'of the clip 104, and moreover, the clip is inserted into the mounting hole 101b provided in the recess 101a in a substantially ⊃-shaped bent shape of the clip 104. It is configured to be inserted and used while elastically deforming the portion 104b.

The clip 104 is an upper piece of the insertion portion 104b having a substantially ⊃ shape which is inserted into the mounting hole 101b while being elastically deformed.
At the free ends of 104b 'and the lower piece 104b ", the operating knob 10 is attached.
4a, 104a ', and the operation knob part on the lower piece 104b "side
104a 'is provided so as to hang down along the surface of the concave portion 101a to the edge of the concave portion and then rises so as to be substantially flush with the surface of the lamp cover 101 to form a gap 104c. Also the upper piece
The operation knob portion 104a on the 104b 'side is provided so as to be substantially orthogonal to the upper piece 104b', the lower side thereof extends toward the gap 104c, and the upper side slightly protrudes from the recess 101a. I am trying.

Then, the engaging convex portion 104d provided on the upper part 104b 'of the insertion portion 104b is covered by the elastic deformation of the insertion portion 104b.
The elastic piece 104e provided on the lower piece 104b ″ is attached by inserting so as to slide in the edge of the hole 101b of 101.
The upper piece 104b 'of 104b is always elastically urged upward.

In such a conventional example, the cover is directed toward the opening 103 of the trim 102.
By rotating 103 and pushing in the operation knob portions 104a and 104a 'of the clip 104, each piece of the insertion portion 104b, particularly the upper piece 10
4b 'is bent downward and the convex portion 104d of the insertion portion 104b is trimmed.
It was configured to be locked to the opening edge of the opening 103 of 102.

(Problems to be solved by the invention) In such a conventional example, the protrusion 104d of the clip 104 is required to be elastically inserted into the upper edge portion of the opening 103 of the trim 102, so that the lamp cover 101 is provided. The recess 101a cannot be set larger than necessary, and in particular, a gap m is formed between the upper edge of the recess 101a and the knob piece of the operation knob 104a.
Is narrow, insert your fingertips in between, and pick the clip 1 of the clip 104.
It was difficult to pull out the lamp cover 101 in the direction of arrow y while pushing down 04a.

Especially when the knob 104a of the clip 104 is projected outward from the recess 101a, a scratching accident or an unexpected cover 101 to the protruding knob 104a is caused.
Therefore, the bending piece portion of the knob portion 104a is usually slightly protruded from the recess 101a.

As a result, the fingertip is inserted into the slight gap m, and in this state, the knob portion 104a is pushed downward and the knob piece portion of the knob portion 104a is pulled out in the direction of the arrow y. It was necessary to pick out the knob piece protruding from the mounting hole 101b.
