A hook may be provided on the side surface of the post and the side surface of the tool box, and a support member may be configured by hanging a chain on the hook, and support may be provided according to the items to be stored.
Next, a modification of the support member according to the present embodiment will be shown. As described above, the support member 11 shown in FIGS. 4 and 5 is rotatably supported with respect to the bracket 10 so that the support member itself does not rotate due to vibration, acceleration / deceleration, inclination, etc. during vehicle travel. It is desirable to support. For this purpose, for example, a member such as a bolt or a pin may be interposed in the bracket 10 or the support member 11 to stop the relative movement of the bracket 10 and the support member. A structure for preventing rotation of the support member that does not require other components such as bolts and pins will be described below.
FIG. 9 is a perspective view of the support member 31 according to this modification. The upper part 31 b of the support member 31 is bent into an L shape, and the hole serving as the center of rotation is constituted by a long hole 31 a along the longitudinal direction of the vertically long support member 31. FIG. 8 is an explanatory view of attachment of the support member 31 corresponding to the arrow view of FIG. 5 described above, and the support member 31 is attached to the post 12 via the bracket 10 via the member 32 as a rotation center. This shows the state. 7 is a view of the mounting state of the support member of FIG. 8 as viewed from the rear of the vehicle, and FIG. 10 is a view of the mounting state of the support member of FIG. 7 as viewed from the side.
As shown in FIG. 7, the support member 31 is in a state in which a ring stop (not shown) is retracted, and in a posture standing upright in the gravitational direction as shown by a solid line, the support member 31 is attached to the member 32 with the upper portion of the elongated hole 31 a as the center of rotation. Supported. In this state, when the support member itself tries to rotate due to vibration, acceleration / deceleration, inclination, etc. during traveling of the vehicle, the portion of the upper portion 31b of the support member 31 bent into the L shape is the upper contact portion 10a of the bracket 10. The movement of the support member about to rotate can be stopped. This is because the center of rotation of the support member 31 moves to the upper part of the elongated hole 31a due to the gravity of the support member 31, so that the portion of the support member upper part 31a bent in the L shape can prevent the rotation. .
As shown in the arrow “b” in FIG. 7, the support member is once lifted upward along the elongated hole 31 in the direction of gravity as shown in the arrow “b”. Rotate to and store. Here, when the rotation center of the support member 31 is positioned below the elongated hole 31a, the upper contact portion 10a of the bracket 10 has a length 10b that does not contact the portion of the support member 31 that is bent into the L shape. Since it is configured, it can be rotated. Thereby, this modification can be stored (or taken out) by a simple operation of rotating while lifting the support member by hand, and when the rotation is to be prevented using a bolt or a pin. It exhibits excellent operational effects that do not require any extra work.
In the description of the embodiments and the modifications so far, an example of an aerial work vehicle has been described as a work vehicle. However, the work vehicle is not limited to an aerial work vehicle, and is a work vehicle having a post under a swivel. If there is, the storage space can be effectively utilized by applying the configuration of the present application.
