Abstract

PURPOSE:To provide so as to prevent a mounting part from being turned around the axis of a pipe in hooking or removing an article by mounting the mounting part connected to a hook part on two parallel pipes of a pipe rack to span the pipes. CONSTITUTION:A hook device is provided with a mounting part 20 mounted on two pipes P1, P2 to span them and a hook part 30 formed integrally with the front end of the mounting part 20 to be suspended therefrom. A first pipe holding part 21 is hooked on one pipe P1 and a second pipe holding part 22 is fitted from above on the other pipe P2 so that the hook device can be easily mounted. Since the mounting part 20 is mounted to span two pipes P1, P2, when an article such as scrub brush is hooked on or removed from a hook 33 of the hook part 30, the mounting part 20 is not pivoted about the axis of the pipe to provide convenience for use. Moreover, the mounting part 20 is mounted stably in the vertical and back and forth directions relative to the pipe to provide further better convenience for use.
