[Prior Art] As a seat cushion opening / closing mechanism of a locomotive, for example, a structure described in a conventionally disclosed in "2001's seat cushion of a Sukoda vehicle" is known. The second diagram of the above publication will be described below with reference to FIG. 25. Figure New labeling. FIG. 25 is a perspective view showing a conventional seat cushion opening and closing structure. The front part of the box 3 0 1 is a seat cushion 303 that can be opened and closed freely through a seat cushion hinge 3 2. A first door is installed on the bottom surface of the seat cushion 303. In order to support the first door-shaped fitting 3 0 5, a first seat cushion locking mechanism 3 0 6 is arranged on the side of the storage box 3 0 1 to support the first door-shaped fitting 3 0, and the second Π-shaped fitting 3 0 5 and a seat cushion locking mechanism 3 07 is arranged at the rear of the storage box 3 01, describing the seat cushion opening and closing structure thus constituted. [Summary of the Invention] [Problems to be Solved by the Invention] As described above, a first seat cushion lock is provided. The mechanism 3 0 6 and the pad locking mechanism 3 07 can prevent the large seat cushion 3 0 3 from being opened, and if the number of the locking mechanism can be made one, it is heavier than the Japanese special structure number of the car body. Pieces 3 04 3 04 and can be arbitrarily supported in order to support the second and second seat. -5- (2) (2) 200401728 Reduces the cost of the part itself and the installation cost, and does not need to be used to connect the first seat cushion locking mechanism 3 06 with the second seat cushion locking mechanism 3 07 the second cable 3 0 8 can also be In order to reduce the cost of steel cables. An object of the present invention is to improve the seat cushion opening and closing structure of a locomotive, and in particular, for a locomotive provided with a large-sized seat cushion, the seat cushion locking mechanism, that is, the seat cushion buckle, can be reduced to one. [Means for solving the problem] The first invention for achieving the above-mentioned object is to provide an article storage box under the seat cushion, and the seat cushion can be opened and closed freely through seat cushion hinges provided on the left and right sides of the seat cushion. The seat cushion opening / closing structure of the locomotive tilts the hinge shaft so that the front portion approaches forward and downward from the side and the front portion approaches from the top toward the inside of the vehicle body. When the seat cushion is closed, the seat cushion bottom plate is made. The convex portion provided on the front portion is engaged with the concave portion provided on the front portion of the article storage box. In the past, in order to prevent theft due to deformation of the seat cushion, when the seat cushion is closed, a seat cushion buckle that engages the seat cushion on the side of the vehicle body is installed at two positions. In the present invention, The engagement of the article storage box and the seat cushion is performed by the concave portion on the article storage side and the convex portion on the seat cushion side, so a seat cushion buckle can be saved, which can maintain the anti-theft function and reduce cost. The second invention is to pass the hinge shaft through the vicinity of the lower portion of the engaging portion. By passing the hinge shaft near the lower part of the engaging portion, the seat cushion is closed and the recessed portion on the storage box side and the convex portion on the seat cushion are engaged with each other, even if an upward force is applied to the seat cushion If you want to open the seat cushion, the seat-6-(3) (3) 200401728 is also difficult to rotate around the hinge axis, and the seat cushion is difficult to open, which can improve the anti-theft effect. According to a third invention, a recessed portion is formed in an opening flange portion of an upper portion of the article storage box. Since the recessed portion is formed at the opening flange portion of the upper portion of the article storage box, the shape change of the article storage box forming the recessed portion can be reduced compared to the case where the recessed portion is specially made, and the cost can be reduced. The flange portion is a rigid portion of the upper edge portion of the article storage box. Therefore, by providing the recessed portion to the flange portion having higher rigidity, even when external force acts on the recessed portion via the convex portion on the seat cushion side, It is also possible to suppress deformation of the concave portion.
