1. A clip comprising:
a pin including a head portion and a shaft portion provided under the head portion, a first engaged portion and a second engaged portion both being provided on the shaft portion; and
a grommet having a flange with an insertion hole, a leg portion projecting from a lower surface of the flange and an engaging portion engaging with and disengaging from the respective engaged portions, the clip changing a temporary fixing condition where the engaging portion engages the first engaged portion in a course of arranging the pin to the grommet such that the shaft portion is inserted into the leg portion through the insertion hole, to a permanent fixing condition where the engaging portion is engaged with the second engaged portion after the leg portion is elastically enlarged by further insertion of the shaft portion,
wherein the grommet includes the engaging portion around an inner periphery of the insertion hole of the flange,
the pin includes a guide groove having a linear groove portion between the first engaged portion of the shaft portion and the second engaged portion and a curved groove portion in a curved shape provided along an upper side of the linear groove portion, the guide groove guiding movement of the pin in a condition of slidably engaging the engaging portion, and a projection formed at an upper end of the linear groove portion as the second engaged portion, and
when the pin where the engaging portion is in the temporary fixing condition is pushed, the engaging portion slides and rides over the projection and the pin comes to the permanent fixing condition, and when the pin is rotated such that the engaging portion disengages from the projection and enters the portion, the pin moves upwardly and the engaging portion contacts the curved groove portion so that the pin changes from the permanent fixing condition, and the engaging portion is able to engage the first engaged portion.
