Definitions
- the present invention relates to a stopper used when, for example, an interior / exterior part of an automobile is fixed to a panel or two panels are overlapped and fixed.
- This type of stopper is composed of two parts, a grommet and a pin.
- Grommets have flange and leg parts. The leg is pushed into the mounting hole of the fixed object. Then, when the pin is pushed into the central shaft portion of the grommet, the pushing pressure force of the pin acts on the leg portion, and the leg portion expands outward. In this way, the grommet is fixed to the mounting hole of the fixed object.
- this type of conventional stopper includes a structure in which a grommet and a pin are partially connected to facilitate handling during transportation.
- each of the stoppers disclosed in each of these patent documents has a structure in which the grommet and the pin are integrally removed by opening and closing the mold from the lateral direction. Therefore, in order to die-cut the pin arranged at the central shaft portion of the grommet, it was necessary to divide the grommet flange into two parts and to die-cut the pin with the gap force of each flange.
- the flange of the grommet has a two-part structure, which has the disadvantage that it is difficult to apply a uniform pressure to the grommet when the leg part of the grommet is pushed into the mounting hole of the fixed object.
- stopper that is connected to a pin by dividing the grommet flange without dividing the flange.
- Examples of this type of stopper include those disclosed in patent documents such as US4276806, US4405272, US4856950, US2005-0220561A1, and the like.
- the stoppers disclosed in each of these patent documents are all made from the central axis direction of the grommet. It has a structure in which a die is inserted and a pin is removed. For this reason, the legs of the multiple legs that extend from the flange of the grommet are separated from each other, and each leg is independent.
- US4571134 and US5704746 disclose a stopper having a structure in which a plurality of legs are connected at the tip, and a pin is connected to the flange of the grommet, without being subjected to flange damage ij. .
- the stoppers disclosed in these patent documents have a structure in which the lower end of the pin is connected to the flange. That is, the pin extends to the front surface side of the flange, and is pushed through the position force flange to the back surface side.

It can be reliably transmitted to the leg part via the convex part, whereby the leg part can be smoothly pushed into the mounting hole of the fixed object.
- the portion where the convex portion for expanding and holding is passed through the fixing hole of the fixed object, the portion of the leg portion can be expanded outward, and the tip of the shaft portion of the pin is located between the convex portions for expanding and holding. It penetrates and pushes the projections for holding the expansion outward. Thereby, a leg part is reliably latched by the hole edge of an attachment hole.
- the shaft portion is separated from the grommet, and a convex portion for preventing the drop-off is formed at a position opposite to the head portion via the flange, and the convex portion for preventing the drop-off from the flange.
- the omission is regulated.
- a small piece connecting the bridge of the flange and the shaft portion of the pin is formed.
- the small piece supports the outer peripheral force of the pin, so that rattling of the pin in the radial direction can be suppressed.
- a guide surface is formed on the shaft portion of the pin to which the small piece protruding from the bridging force of the flange slides.
- a projecting guide portion is formed on the shaft portion of the pin to guide the pin in sliding contact with the bridge end surface of the flange from the middle when the pin is pushed into the grommet.
