Numeral 8 is a wheel mounting bolt screwed into each screw hole 3 of the hub 1 through each bolt through hole 7. In an imported passenger car, four to six bolts 8, usually five or six mounting bolts are used. The wheel 5 is attached to the hub 1 by bolts 8.

In the present invention, the tread is widened by interposing a spacer member to be described later between the wheel 5 and the hub 1 having the above-described mounting configuration, so that the tread will be described with reference to FIGS. .

Reference numeral 9 denotes a spacer body of the wide tread spacer of the present invention, which is formed by an annular disk having a center hole 9a fitted in the hub center 4 at a center and having a thickness of about 15 to 30 mm. It has the following configuration. That is, on the outer periphery of the center hole 9a, there is a bolt through hole formed with a countersunk portion 10a in the shape of a deep dish on the inlet side of the hole, the bolt through hole 10 corresponding to each screw hole 3 of the hub 1. In this example, five bolt holes are formed, and the bolt nut holes 12 on the wheel 5 are fitted in the middle of the bolt hole holes 10 adjacent to each other, and a detent nut member 12 described later is fitted. In this example, five holes 11 (hereinafter, referred to as mounting holes 11) for receiving and mounting a nut member for mounting are formed.

As shown in FIGS. 2 and 3, the nut member mounting hole 11 forms a round hole 11 a with a bottom from the rear surface side of the spacer body 9 (the non-sinking side of the bolt through hole 10). In addition, a groove 11b concentric with the center of the spacer body 9 and passing through the center of the round hole 11a and having a width smaller than the diameter of the round hole 11a is formed on the front side of the body 9 by cutting. By doing so, it is formed as a stepped irregular hole having the bottomed round hole 11a, the groove 11b, and a bottom 11c on the inner diameter of the round hole 11a left when the groove 11b is formed by cutting. It has been done.

The rotation preventing nut member 12 shown in FIGS. 4 and 5 is mounted in the mounting hole 11 of the rotation preventing nut member formed as the stepped irregular hole. That is, the nut member 12 is formed on its front side with a convex portion 12a which functions as a detent key by being fitted to and fitted with the groove 11b in the mounting hole 11, and each bolt 8 The main body 12c is formed in a circular short column shape that fits into and fits with the round hole 11a in the mounting hole 11. Although knurls are cut on the outer peripheral surface of the main body 12c, whether or not knurls are formed is optional.

With the above-described configuration, the wide tread spacer for an imported vehicle of the present invention is formed, and the mounting is performed as follows. First, the wheel 5 attached to the hub 1 with the five bolts 8 is loosened and the bolts 8 are removed, and the wheel 5 is once removed from the hub 1. On the other hand, in the wide tread spacer of the present invention, a nut member 12 shown in FIGS. 4 and 5 is inserted into each nut member mounting hole 11 in the spacer body 9 from the side of the round hole 11a in the mounting hole 11. The convex portion 12a of the main body 12c fits into the groove 1b, and the front surface 12d of the main body 12c contacts the bottom 11c of the round hole 11a. The member 12 fits in the mounting hole 11 in a non-rotatable manner.

The spacer body 9 in which the rotation preventing nut member 12 is mounted in the mounting hole 11 is fitted into the hub 1. At this time, the center hole 9 a of the spacer body 9 is inserted into the hub center 4 of the hub 1. Then, the bolt holes 10 of the spacer body 9 are aligned with the screw holes 3 of the hub 1.

A spacer mounting bolt (not shown) having a square hole for a square wrench such as a hexagon wrench on the dish-shaped head is inserted into each bolt through hole 10 in the spacer body 9 mounted on the hub 1, The spacer body 9 is fastened and fixed to the hub 1 by screwing the bolt with the square hole into the screw hole 3 with a square wrench tool. The wheel 5 is fitted into the hub 1 on which the spacer body 9 is mounted. At this time, the bolt holes 7 of the wheel 5 are aligned with the screw holes 12b of the nut member 12 of the spacer body 9, and the five bolts are inserted. 8 is screwed into each screw hole 12b through each through hole 7 and tightened. Thus, the wheel 5 is attached to the hub 1 via the spacer body 9. As a result, the wheel 5 attached to the left and right hubs 1 has the spacer body 9 attached to the left and right hubs 1, so that the thickness of the spacer body 9 is twice (by the left and right wheels). The tread is widened by the minute.

[Effect of the invention]

 As described above, the present invention is very useful as a spacer for widening the tread of an imported passenger car that does not have a stud bolt for mounting a wheel on a hub.

In particular, in the present invention, a nut member for tightening a wheel mounting bolt is fixedly mounted on the spacer main body side so as not to rotate, and is set within the thickness of the spacer main body. Therefore, there is an advantage that the tread can be easily widened even in an imported vehicle in which a bolt mounted on a hub is fastened with a bolt to a screw hole on the hub side.

Further, a structure for non-rotatably mounting the nut member to the spacer body is provided by forming a bottomed hole on one side of the spacer body, and the spacer body from the other side of the spacer body with respect to the bottomed hole. A groove is formed concentrically with the center of the hole, and the groove is communicated with the hole, so that the bottomed hole is formed as a through hole with a key groove, while the hole with the key groove is fitted and fitted. A nut member having a screw hole formed at the center thereof is housed in the hole, so that a non-rotatable nut member is mounted on the spacer body by a simple structure. It has the unique effect of being able to do things.
