(Operation of the embodiment)
The usage method of the vehicle hand pushing movement aid 10 comprised as mentioned above is demonstrated.
As shown in FIGS. 4 and 5, the worker attaches the connecting device 40 to the vehicle wheel 140 shown in FIG. 3. Specifically, as shown in FIG. 5, the operator inserts each cylindrical portion 62 of the torque transmitting portion of the connecting device 40 into each mounting hole 120 and enters the fitting hole 65 of the cylindrical portion 62. The hub nut 100 is fitted. At this time, the inner peripheral surface and the outer peripheral surface of the cylindrical portion 62 abut against the inner peripheral surfaces of the hub nut 100 and the mounting hole 120 through the cushioning material 63, respectively. Therefore, the hub nut 100 and the mounting hole 120 are not damaged during the subsequent operation. In this state, the operator passes the belt 56 shown in FIGS. 2 (a) and 2 (b) between the wheel spoke portions 114 a of the disc wheel 114 to secure the base member 50 to the disc wheel 114. . The operator sets the length of the belt 56 to an appropriate length in advance by using the length adjustment buckle 59, and ties the belt 56 by connecting the insertion buckles 57 and 58 to each other. To do. In the state where the base member 50 is secured, as shown in FIG. 5, the torque input portion 70 of the connecting device 40 is arranged coaxially with the axis O of the axle 110, that is, the axis of the wheel 140.

  Next, as shown in FIG. 5, the operator engages the push handle 30 of the ratchet wrench portion 22 in the fitting hole 72 of the torque input portion 70, thereby moving the hand handle 20 to the base member 50 of the connecting device 40. Install against.

  In this state, when the vehicle 150 is to be moved forward, after the reversing lever 28 (see FIG. 1A) of the ratchet wrench portion 22 is set to the normal rotation position, as shown in FIG. Repeat the forward and backward swinging operation.

  When the operation rod 23 is swung in the front-rear direction, the drive protrusion 30 applies a rotational torque to the torque input unit 70 only when the operation rod 23 is operated forward. The rotational torque is transmitted to the disk unit 116 via the base member 50 and the torque transmission unit 60. As a result, the disk wheel 114, that is, the wheel 140 rotates, so that the vehicle 150 moves forward. The vehicle 150 is steered by an operator other than the operator who operates the push handle 20 operating the steering wheel from the driver side door window.

Since the connecting device 40 is secured to the wheel 140 by the belt 56 and the insertion buckles 57 and 58, the connecting device 40 does not fall off when the hand handle 20 is manually pushed.
When the vehicle 150 is to be moved backward, after setting the reversing lever 28 (see FIG. 1A) of the ratchet wrench portion 22 to the reversing position, the operator moves the operation rod 23 in the front-rear direction as shown in FIG. Repeat the swinging operation.

  When the operation rod 23 is swung in the front-rear direction, the drive protrusion 30 applies rotational torque to the torque input unit 70 only when the operation rod 23 is operated rearward. The rotational torque is transmitted to the disk unit 116 via the base member 50 and the torque transmission unit 60. As a result, the disk wheel 114, that is, the wheel 140 rotates, so that the vehicle 150 moves backward. The vehicle 150 is steered by an operator other than the operator who operates the push handle 20 operating the steering wheel from the driver side door window.

  As described above, the operator may accidentally release the hand handle 20 during the swinging operation of the hand handle 20 in the front-rear direction. In this case, the upper end of the operating rod 23 falls on the floor surface or road surface. If the vehicle 150 is moving by inertia at this time, the upper end of the operation rod 23 is moved by being pulled or pushed by the moving vehicle 150. In this case, since the upper end of the operating rod 23 has the roller 29, there is no possibility of being caught by unevenness on the floor surface or road surface. If the roller 29 is not provided, there is a risk that if the hook is released after the upper end of the operating rod 23 is caught by the unevenness of the floor surface or the road surface, the reaction rod will jump upwards vigorously. In this embodiment, since the roller 29 gets over the unevenness, such a situation does not occur.

  When the movement of the vehicle 150 is completed, the operator removes the driving protrusion 30 of the handwheel 20 from the torque input unit 70 of the wheel 140. Thereafter, the operator releases the connection of the insertion buckles 57 and 58 of each belt 56 and removes the connecting device 40 from the disc wheel 114.
