PROBLEM TO BE SOLVED: To facilitate power line connection work by providing an engage- securing member between a pole through which a power line passes and a lamp unit from which a lead comes out, with the engage-securing member having at its fore-end a hook for engaging with the pole and at its middle a terminal block and secured at its tail end to the lamp unit. SOLUTION: To attach a lamp unit 2 to a pole 1, first an engagement hook 9 is made to engage with the brim of a lamp securing portion 6 to temporarily suspend the lamp unit 2. In that state, a power line 4 is secured to an engage- securing member 3 using a lead holder 12, and the fore-end of the line 4 is connected to a terminal block 13 to which a lead 8 of the lamp unit 2 is connected in advance. Next, while releasing the engagement of the engagement hook 9, an attachment portion 7 of the lamp unit 2 is fit to the securing portion 6 of the pole 1 and tightened with a bolt. This makes the connection work between the lead 8 of the lamp unit 2 and the power line 4 of the pole 1 safe and easy so the lamp unit 2 may be attached safely and securely by a single worker. |
