Abstract: A clip is provided which can be brought into engagement with a mounting hole with a relatively low insertion force and which can be pulled out of the mounting hole for reuse. This clip includes a flange portion 16 which is brought into abutment with a front surface of a mounting hole, a stem portion 24 which hangs downwards from a rear surface of the flange portion 16, a pair of elastic engagement pieces 26, 26 which are extended from a distal end portion of the stem portion 24 so as to expand obliquely upwards towards the flange portion 16, and an expansion restriction which brings the elastic engagement pieces 26 into engagement with the stem portion 24 or the flange portion 16 while permitting the elastic engagement pieces 26 to deflect further inwards when the elastic engagement pieces 26 deflect inwards with a given angle.

Abstract: A push nut including a base plate formed with a bolt passing hole at a center of the base plate and four engaging pieces. Pairs of engaging pieces extend respectively from a pair of opposing sides of the base plate, base portions of the four engaging pieces are folded back to have a U-shape, and tip end portions of the engaging pieces extend to a surrounding of the bolt passing hole. The tip end portions of the four engaging pieces surround a periphery of the bolt passing hole. The four engaging pieces incline toward an insertion direction of a bolt and elastically abut against an outer circumference of the bolt, which is inserted into the bolt passing hole.

Abstract: A jointing member has a grommet and a pin. The grommet includes a flange portion and a leg portion capable of being opened, in which an insertion hole is formed from the center of the flange portion to the inner portion of the leg portion, and an engagement portion is formed at the inner surface of the leg portion. The pin includes a head portion and a shaft portion to be inserted into the insertion hole, in which an engagement surface and a lock surface each engaging with the engagement portions are formed at the shaft portion. In the jointed and fixed state of panel members, when an unexpected external force is applied to the tip end of the shaft portion of the pin, the engagement portion engages with the lock surface of the pin.

Abstract: A jointing member has a grommet and a pin. The grommet includes a flange portion and a leg portion capable of being opened, in which an insertion hole is formed from the center of the flange portion to the inner portion of the leg portion, and an engagement nail is formed at the inner surface of the leg portion. The pin includes a head portion and a shaft portion to be inserted into the insertion hole, in which an engagement surface and a lock surface each engaging with the engagement nails are formed at the shaft portion. In the jointed and fixed state of panel members, when an unexpected external force is applied to the tip end of the shaft portion of the pin, the engagement nail engages with the lock surface of the pin.

Abstract: A two-piece clip includes a grommet and a pin. The grommet includes a plurality of elastic leg portions separately extending from a flange. The pin includes a shaft for radially expanding the elastic leg portions when the shaft is inserted among the elastic leg portions through the center hole. At an intermediate portion of the shaft, a temporarily locking piece and a locking protrusion are formed. Both ends of the temporarily locking portion are coupled with the shaft in a shaft direction to have a bridge-like shape. The temporarily locking piece protrudes in an outer radial direction. The locking protrusion is adjacent to the temporarily locking piece in a shaft tip end direction. An inner peripheral edge of the flange is engaged between the temporarily locking piece and the locking protrusion so that the pin is temporarily locked to the grommet.
