At the same time, a through hole 10a was bored in the cylindrical body, the horizontal surface of the short rod was raised directly above the through hole 10a, and a dowel-like locking protrusion 10f was provided to protrude laterally from the raised end to the rear. A pair of locking members 10, 10 are pivotally attached to brackets 5g, 5g which protrude from the side wall of the locking member storage portion 5e oppositely, with through holes 10a, 10a communicating with each other, and the horizontal surface of the locking member 10 is connected to the brackets 5g, 5g which protrude from the side wall of the locking member storage portion 5e. A tension spring 11 is elastically supported between the opposing tips of the locking members 10 and 10 so as to come into pressure contact with the flange 9b of the removal tool 9, and the locking protrusion 1
0b, 10b are opposed to predetermined positions of the handle rod 4 and are removably engaged with locking holes 12 or 13 provided above and below, thereby attaching the bracket 1f to the convex portion 5b provided on the handle rod erecting member 5. The pedestal 1, which is integrally pivoted through the holder 1, is fixed in a horizontal state, and then pulled upward to fix the folded state. A pair of brackets 1g, 1 are placed near the center of the bottom surface of the pedestal 1.
g is vertically installed in a symmetrical position, and a pair of bell cranks 14
One end is pivotally connected to the bracket 1g, the other end of the bell crank 14 is pivotally connected to the rear axle 7, the base end of the stand rod 15 is connected to the center of the bell crank 14, and the ground end of the stand rod 15 is connected to the rear axle 7. It is placed on the front axle 3, and when the pedestal 1 is pulled up, it separates from the front axle 3 and touches the ground. As shown in FIGS. 17 and 18 as another embodiment of the locking member, a locking/unlocking tool 9 is elastically supported by a pressing spring 16 and inserted into a locking member storage portion 5e, and then the locking/unlocking tool 9 and the lock are inserted. An elbow rod-shaped locking member 1 extends over the side wall of the member storage portion 5e.
7 is slidably inserted laterally and in the direction in which the bent portion approaches, and the locking/disengaging tool 9 is provided with a diagonally upward elongated hole 9c to loosely insert the bent portion of the locking member 17.
By pressing the locking/unlocking tool 9 against the elastic force of the pressing spring 16, the bent portion of the locking member 17 is inserted into the elongated hole 9c.
By moving the lock member 17 diagonally upward along the
3, the handle rod standing member 5 is released, and the pedestal 1 is raised and lowered, and the protruding tip of the locking member 17 is engaged with the locking hole 12 or 13 to put it in the use state or This fixes the folded state.
