It is attached by screws 242 and 242 through a screw hole formed in 21, but may be attached to both ends of the rear wheel shaft 123 (see FIG. 7). The socket 20 is fixed so that the bottom end of the cup of the main body 21 is attached to the rear wheel axle 123, and has an outer peripheral surface close to the front end surface 22 of the main body 21 facing outward as shown in FIG. The flat slot 26 is cut in parallel with the front end face 22 from the side facing the front wheel shaft 113 and beyond the center of the main body, and the front end face 22 is moved from the outer peripheral portion where the flat slot 26 opens to the vicinity of the center. A notch 24 is formed across the flat slot 26 so as to be narrower than the flat slot 26 in a laterally U-shape. The U-shaped notch 24 forms an engagement groove 23 inside. Further, protruding ribs 262 and 262 are provided in appropriate positions in the locking groove 23 near the slot opening 27, respectively (see FIG. 9).

As shown in FIGS. 4 and 6, the latch member 30 is a disk 31 having an outer diameter substantially equal to the width of the flat slot 26 of the socket body 21. At the end of the front wheel axle 113 corresponding to the end of the rear wheel axle 123 to which the socket 20 is attached at the outwardly extending tip of the wheel axle 113, for example, a screw hole at the outer peripheral portion is inserted through the end of the front fork 111 322 and 322, and may be attached to both ends of the front wheel shaft 113, respectively. As shown in FIG. 7, the latch member 30 is provided with a recessed mounting hole 32 at the rear end for mounting to the distal end of the front wheel shaft 113. Then, an annular groove 36 having an appropriate depth from the outer peripheral portion near the distal end surface 34 is formed, so that the distal end portion becomes a flat head 38, and the flat head 38 is inserted into the flat slot 26 of the socket body 21. The outer peripheral edge can be engaged so as to fit into the locking groove 23. As shown in FIG. 8, in the latch member 30, a plurality of through-holes, which are symmetrical from the end surface of the disc 31 to appropriate locations around the mounting hole 32, are, for example, four through-holes 324, 324. , 324 and 324 can also be formed. By doing so, the weight of the latch member 30 can be reduced.
