Description of the Invention: [Technical Field of the Invention] The present invention relates to a car toy having a tail fin member. [Prior Art] Conventionally, in a car toy, it is known that a rear wing member is provided at a rear end portion. The empennage member is a mounting structure that models a turbulent empennage of an actual automobile, that is, a two-frame member that is disposed in a straight flat plate shape in the vehicle width direction, and is attached to the vehicle body (for example, Patent Document 1) Reference). [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] Japanese Patent Publication No. 56-31270 (Description of the Invention) However, in the automobile toy, the support frame member is a straight flat plate. Therefore, when the empennage member is brought into contact with the wall, the road surface or the like due to rolling or the like, the support frame member may be plastically deformed and broken due to local stress concentration. The present invention has been made in view of the above problems, and an object thereof is to suppress plastic deformation and breakage of a support member to which a empennage member is attached. (Means for Solving the Problem) -5- 201143867 In order to solve the above problem, as in the invention of claim 1, the empennage member is attached to the body of the vehicle body through the support frame member, and is characterized in that: the support frame member A bending portion 0 which is curved in the front-rear direction of the vehicle body, as in the invention of claim 2, is an automobile toy according to claim 1, wherein the support frame member is constituted by the bent portion. The invention of claim 3 is the automobile toy of claim 1 or 2, wherein the curved portion is <shaped, S-shaped or z-shaped. The invention of claim 4 is the automobile toy of claim 1 or 2, wherein the support frame member is attached only to one central portion of the tail member in the vehicle width direction. The invention of claim 5 is the automobile toy of claim 1 or 2, wherein the support frame member is formed of an elastic member. [Effects of the Invention] According to the invention of claim 1, the support frame member has a curved portion that is curved toward the front-rear direction of the vehicle body, so that even if the external force in the front-rear direction acts on the tail member, The external force is dispersed corresponding to the bending angle of the curved portion. Moreover, since the elastic deformation is easily performed by bending, the plastic deformation of the support frame member can be suppressed. Further, even if the external force in the left-right direction acts on the empennage member, compared with the conventional linear support member of the straight -6-201143867, since the bent portion becomes long, it is easily elastically deformed, and the support can be suppressed. Plastic deformation of the frame member. By the above, the local stress concentration in the support member to which the empennage member is mounted can be alleviated, and plastic deformation and breakage of the support frame member can be suppressed. According to the invention of claim 4, the support member is only one of the central portions in the vehicle width direction of the empennage member, so that the empennage member is compared with the conventional two support members. The external force acting in the oblique direction can be withstood by the minimum torque. Therefore, plastic deformation and breakage of the support frame member can be further suppressed. According to the invention of claim 5, since the support frame member is formed of an elastic member, it is more easily elastically deformed, and plastic deformation and breakage of the support frame member can be further suppressed. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an external view of the car toy 1 in the present embodiment.

By charging the start button 92, it is possible to supply electric power from a built-in battery (not shown) and to drive the car toy! Battery charging. Moreover, the power supply LED 93 and the charging LED 94' are provided in the charger 9, and the ON/OFF state of the power supply can be determined by turning on/off the power LED 93, and can be lit by charging the LED 94. / Eliminate the light to determine the charging / charging is completed. According to the above-described automobile toy 1, the support frame member 71 has a curved portion that is curved toward the front-rear direction of the automobile toy 1, so that even if an external force in the front-rear direction acts on the empennage member 7, it can be dispersed corresponding to the bending angle of the curved portion. The external force. Moreover, since it is easily elastically deformed by bending, plastic deformation of the support frame member 71 can be suppressed. Further, even if the external force in the right and left direction acts on the empennage member 7, compared with the conventional linear support member, since the bent portion becomes long, it is easily elastically deformed, and the support member 71 can be suppressed. Plastic deformation. With the above, local stress concentration in the support member Ή in which the empennage member 7 is mounted can be alleviated, and plastic deformation and breakage of the support frame member 71 can be suppressed. Further, since the frame member 71 is supported, since only one central portion in the vehicle width direction of the empennage member 7 -12- 201143867 is installed, the direction of the empennage member 7 is inclined in comparison with the conventional arrangement of the two support frame members. The external force acting can be withstood by the minimum torque. Therefore, plastic deformation and breakage of the support frame member 7 1 can be further suppressed. Further, since the support member member 71 is formed of an elastic member, it is more easily elastically deformed, and plastic deformation and breakage of the support frame member 71 can be further suppressed. Further, the present invention is not limited to the above embodiments, and it is of course possible to carry out appropriate modifications and improvements. For example, in the above embodiment, the support frame member 171 may have a bent portion, but may be constituted by a bent portion, that is, without a straight portion. Further, the curved portion of the support frame member 71 is not limited to the S-shape, and may be curved in the front-rear direction, such as a font or a zigzag shape. However, in order to suppress plastic deformation or the like of the support member 7 1 in the oblique direction of the tail member 7 toward the left and right, the curved portion of the support member 71 may be bent in the left-right direction. Here, the "bending" in the present invention is not only a narrow sense of curvature, but also a generalized concept of "buckling" and "bending", and as shown in Fig. 8, in the car toy 1, the setting is omitted. The strip-shaped roll preventing ring 10 is preferred. The roll preventing ring 1 is formed of a transparent polycarbonate and is fixed to the back surface of the lower front wheel chassis 51 so as to surround the automobile toy 1 at a slight center portion in the front-rear direction. Further, in the upper end portion of the roll preventing ring 10, the two projections 10a and i〇a in the front-rear direction are formed in different circumferential directions so that the center of the vehicle width direction is 13-201143867. By providing such a roll preventing ring 10, in addition to the case where the car toy 1 can be side-rolled, the roll preventing ring i can come into contact with the wall and the road surface to return the posture of the car toy 1. . Further, even if the car toy 1 is reversed, since it becomes an unstable reverse state supported by the tip end of the protrusion 10a, the front wheels 21, 21 are steered and the rear wheels 3 1 and 31 are driven to be more reactive. Then, the posture of the car toy 1 can be restored. BRIEF DESCRIPTION OF THE DRAWINGS [Fig. 1] An external view of a car toy in an embodiment.
