Are formed. Furthermore, the slits are formed in two opposing portions near the intermediate portion in the axial direction of the shaft portion 1b.
Opposing projections 1e projecting outward in a direction intersecting with the axial direction are provided opposite to each other with 1d interposed therebetween.

The supporting member 2 in this embodiment, which is shown in the vicinity of the end in FIG. 3, is a rod-shaped member formed from a plastic material (by injection molding). ) Is provided so as to extend in the axial direction, and an arc-shaped cross section is formed at an intermediate portion of the mounting hole 2a so as to correspond to the engaging projection 1e of the application body 1. An engagement recess 2b, which is an annular groove, is provided.

The engaging projection 1e of the coating body 1 here
Has a saw blade shape in an axial section, as shown in FIGS. As a result, FIG.
Also, in FIG. 2, the side facing downward is gently inclined, so that when the application body 1 is inserted into the mounting hole 2a of the support member 2, it is easy to insert the shaft portion 1b elastically deformed by the slit 1d. Can be Further, when the engaging convex portion 1e and the engaging concave portion 2b of the support member 2 are fitted to each other, the side portion of the coating body 1 facing the upper side of the engaging convex portion 1e is oriented with respect to the axial direction of the shaft portion 1b. Since it forms a right angle and is firmly hooked on the engaging recess 2b, it is possible to effectively prevent the entire application body 1 from falling out of the mounting hole 2a of the support member 2.

Further, in this embodiment, when the application body 1 is mounted in the mounting hole 2a of the support member 2, an adhesive is previously filled in the inside of the slit 1d of the application body 1 and the shaft portion 1b of the application body 1 An adhesive is also applied to the outer peripheral surface of the body, and before the adhesive is cured, the shaft 1b of the application body 1 is
Into the mounting hole 2a. Thereby, the shaft portion 1b of the application body 1
Is completely inserted into the mounting hole 2a of the support member 2, as shown in FIG. 1, the engagement protrusion 1e of the application body 1 is fitted into the engagement recess 2b of the support member 2, and the bonding is performed in this state. The agent will cure. When the application body 1 is inserted, since the adhesive is not cured, the elastic deformation of the shaft portion 1b toward the slit 1d at the portion corresponding to the slit 1d is performed without hindrance.

Therefore, according to the structure for supporting a cosmetic-applied body of this embodiment, the engaging concave portion 2b of the supporting member 2 and the engaging convex portion 1e of the applied body 1 engaged with the engaging concave portion 2e are hooked. Thus, it is possible to structurally prevent the application body 1 itself from falling out of the mounting hole 2a of the support member 2.

Further, in the support structure of the applied body for cosmetics of this embodiment, the entirety of the slit 1d of the applied body 1 is filled with an adhesive, and the adhesive is further applied to the slit of the applied body 1. Since the coating is applied from inside 1d to the periphery thereof (the contact surface between the coating body 1 and the support member 2), in addition to the above-described effect of suppressing the elastic deformation, the mounting hole of the support member 2 is provided.
When an external force is applied in the direction in which the application body 1 comes off from 2a,
The adhesive force of the adhesive applied to the periphery of the application body 1 can alleviate the tensile force acting on the engaging portion between the support member 2 and the application body 1 and reliably prevent the application body from slipping out of the support member. Can be prevented. Further, even when the adhesive is deteriorated and the adhesive force is reduced, as described above, the structural protrusion is prevented by the engaging convex portion 1e of the application body 1 and the engaging concave portion 2b of the support member 2. The effect will be maintained.

Although the present invention has been described above with reference to the illustrated examples, the present invention is not limited to the above-described embodiment. For example, the slit 1d serving as a relief space for the coating body 1 is provided on the outer periphery of the shaft portion 1b of the coating body 1. Any shape may be used as long as the engaging projection 1e projecting from the shaft has a shape capable of being displaced inward from the outer periphery by elastic deformation, and a cross section in a direction perpendicular to the axis has a C-shape. Alternatively, a shaft portion having a clearance space formed radially or a shaft portion having a clearance space formed as a hole from an end may be used.

Further, the engaging projection 1e of the coating body 1 is
What is necessary is just to have a shape which can be effectively engaged with the engaging recess 2b of the support member 2 against the force in the direction of pulling out. On the other hand,
The engagement concave portion 2b of the support member 2 may also be locally provided corresponding to the engagement convex portion 1e of the application body 1 so as to prevent the rotation of the application body 1. In addition, the engaging protrusion 1e of the coating body 1 is elastically deformed by the slit 1d, so that the supporting member 2e is elastically deformed.
The number of the engagement protrusions 1e may be more than one in the axial direction or the circumferential direction, or may be formed only on one side of the shaft portion 1a. . Further, the positional relationship between the engaging portions provided on the application body 1 and the support member 2 is reversed, and
It is also possible to provide each of the support members 2 with an engagement projection.
