PROBLEM TO BE SOLVED: To provide a locking structure which prevents a sudden change of an operating force and can improve the operability by increasing a bending load acting on an elastic piece stepwise when a tip of an elastic piece of a first structural material rides over a locking protrusion on a second structural material and can prevent breakage of the elastic piece due to a sudden flexure deformation.SOLUTION: When a tip 111 of an elastic piece 11 equipped on a first structural material 10 rides over a locking protrusion 31 on a second structural material 30 while the tip 111 of the elastic piece 11 performs flexure deformation, a locking hole 12 formed on the tip 111 side of the elastic piece 11 is engaged with the locking protrusion 31 to bring the first structural material 10 and the second structural material 30 into the connection state. Therein, the second structural material 30 is a protrusion provided on the side where the elastic piece 11 of the locking protrusion 31 is introduced and is provided with an introduction protrusion 32 which is protruded into a height lower than the locking protrusion 31 and induces the tip 111 of the elastic piece 11 to an intermediate position of protrusion height of the locking protrusion 31. |
