The male threaded portion 23 of the tow hook 20 is screwed into the threaded portion 16) from the front of the vehicle, and the tow hook 20 is attached to the hook mounting bracket 9 on the front side (state of using the hook on the front side of the vehicle).
反対に、車両の後端部に牽引ロープを掛け止める場合、後側のフック取付ブラケット１０から牽引フック２０を取外し、図５に示すように、後側のフック取付ブラケット１０のネジ孔１５（後開口雌ネジ部１７）に牽引フック２０の雄ネジ部２３を車両後方から螺合して、牽引フック２０を後側のフック取付ブラケット１０に再度取付ける（車両後側のフック使用状態）。
On the other hand, when the towing rope is hooked to the rear end of the vehicle, the tow hook 20 is removed from the rear hook mounting bracket 10, and as shown in FIG. The male threaded portion 23 of the tow hook 20 is screwed into the opening female threaded portion 17) from the rear of the vehicle, and the tow hook 20 is reattached to the hook mounting bracket 10 on the rear side (state of using the hook on the rear side of the vehicle).
本実施形態によれば、牽引フック２０を使用しないフック非使用時には、雄ネジ部２３を後側のフック取付ブラケット１０の前開口雌ネジ部１６に車両前方から螺合して、牽引フック２０を後側のフック取付ブラケット１０に取付ける。これにより、牽引フック２０は、車体フレーム１から前後双方に突出しない格納状態となる。
According to this embodiment, when the tow hook 20 is not used and the hook is not used, the male threaded portion 23 is screwed into the front opening female threaded portion 16 of the hook mounting bracket 10 on the rear side from the front of the vehicle, and the tow hook 20 is attached. It is attached to the hook attachment bracket 10 on the rear side. As a result, the tow hook 20 is in a retracted state in which it does not protrude from the vehicle body frame 1 in both the front and rear directions.
牽引フック２０を前方で使用するフック使用時（前側使用時）には、後側のフック取付ブラケット１０の前開口雌ネジ部１６と雄ネジ部２３との螺合を解除して牽引フック２０を後側のフック取付ブラケット１０から取外し、前側のフック取付ブラケット９の前開口雌ネジ部１６に雄ネジ部２３を車両前方から螺合して、牽引フック２０を前側のフック取付ブラケット９に取付ける。牽引フック２０の使用が終了したら、牽引フック２０を前側のフック取付ブラケット９から取外し、後側のフック取付ブラケット１０に車両前方から螺合して格納する。
When the tow hook 20 is used on the front side (when used on the front side), the screw engagement between the front opening female screw portion 16 and the male screw portion 23 of the hook mounting bracket 10 on the rear side is released, and the tow hook 20 is removed. The tow hook 20 is attached to the front hook mounting bracket 9 by removing it from the rear hook mounting bracket 10 and screwing the male screw part 23 into the front opening female screw part 16 of the front hook mounting bracket 9 from the front of the vehicle. When the use of the tow hook 20 is finished, the tow hook 20 is removed from the hook mounting bracket 9 on the front side and is stored by being screwed into the hook mounting bracket 10 on the rear side from the front of the vehicle.
一方、牽引フック２０を後方で使用するフック使用時（後側使用時）には、前側使用時と同様に牽引フック２０を後側のフック取付ブラケット１０から取外し、後側のフック取付ブラケット１０の後開口雌ネジ部１７に雄ネジ部２３を車両後方から螺合して、牽引フック２０を後側のフック取付ブラケット１０に再度取付ける。牽引フック２０の使用が終了したら、牽引フック２０を後側のフック取付ブラケット１０から一度取外し、後側のフック取付ブラケット１０に車両前方から螺合して格納する。
