Patent ID: 8333540

Claim:
A clip formed of synthetic resin, comprising: a head portion; and a locking leg vertically extending from a lower surface of the head portion, the clip being capable of being immovably mounted to a panel by inserting the locking leg into a mounting hole of the panel, wherein the locking leg comprises: a shaft portion vertically extending from a center of the lower surface of the head portion; and at least three elastic locking members which are arranged at given intervals at an outer periphery of the shaft portion, each of the elastic locking members having an upper end which is connected to the lower surface of the head portion, and a lower end including two portions which are respectively provided on two sides thereof and which are respectively connected to the shaft portion via connection ribs extending from the shaft portion, wherein a connection portion between each of the upper ends of the elastic locking members and the lower surface of the head portion and a connection portion between an upper end of the shaft portion and the lower surface of the head portion are arranged separately such that the upper ends of the elastic members are not directly connected to the shaft portion, wherein the outer periphery of the shaft portion, except for the connection ribs, is situated on an inner side of an inner periphery of the elastic locking members, and wherein the shaft portion and the elastic locking members are configured such that when the locking leg is inserted into the mounting hole of the panel, the inner periphery of the elastic locking members does not come into contact with the outer periphery of the shaft portion; wherein the shaft portion comprises protrusions extending along an axial direction thereof, the protrusions being arranged at positions substantially between positions of the elastic locking members; wherein upper ends of the protrusions are connected to the lower surface of the head portion; wherein lower ends of the protrusions constitute the connection ribs; wherein an outer periphery of the protrusions except for the connection ribs is separated from and situated on the inner side of the inner periphery of the elastic locking members; wherein the at least three elastic locking members comprise four elastic locking members arranged at intervals of approximately 90 degrees with respect to the shaft portion; wherein, of the four elastic locking members, a pair of the elastic locking members that are opposed to each other are wider in width and thinner in thickness than another pair of the elastic locking members that are opposed to each other; and wherein the protrusions comprise a first pair of protrusions that extend respectively toward two sides of one of the wider elastic locking members, and a second pair of protrusions that extend respectively toward two sides of another of the wider elastic locking members, and wherein each of the first and second pairs of protrusions forms an acute angle.
