According to the fourth aspect of the present invention, the connecting member for connecting the two members according to the first, second, or third aspect is further provided with a retaining projection of the female component which is connected to the mounting hole. The female tool has a configuration formed on an elastic plate portion divided by two split grooves formed at intervals along the fitting direction of the female tool.

According to this configuration, by adjusting the thickness and width of the elastic plate portion, the resistance force when the male tool is inserted into the female tool and the engaging force between the two can be simplified as required. In addition to being able to be set to the above, even when the female tool and the male tool once hooked are separated, the elastic plate portion can be bent in accordance with this separation operation, so that the retaining projection is damaged. It is difficult for the male tool and the female tool to be engaged again again even after the separation in this manner.

According to a fifth aspect of the present invention, the connecting member of the two members according to the first, second, third or fourth aspect further comprises a pressing projection of the male member. Extends in the fitting direction of the male tool into the fitting space of the female tool, and
In a state in which a space allowing bending is provided between the male member and the main body portion, both ends are formed on elastic plate portions connected to the main body portion, respectively.

According to this configuration, by adjusting the thickness and width of the elastic plate portion, it is possible to easily set the resistance force when fitting the male tool into the female tool as necessary. In addition to the above, even when the female tool and the male tool once engaged with each other are separated from each other, the elastic plate portion can be bent in accordance with this separating operation. Even after the separation, the male tool and the female tool can be properly engaged again and combined.
