Furthermore, a fitting hole 2a is formed on the upper surface of the battery case cap 2 for fitting a switch button of a switch button portion, which will be described later, from the inside of the battery case cap 2 and projecting it outward.

Further, in order to facilitate fitting with a spring set plate, which will be described later, on the lower surface of the inner wall of the battery case cap 2, the diameter becomes smaller toward the end on the opposite side to the diameter of the opening. Such a taper is provided.

Reference numeral 5 is a printed circuit board for turning on / off the power supply, blinking the LED 6 and an electric light provided in the front portion of the battery case 1 (not shown), and 7 is formed of a material having water resistance and elasticity such as rubber. This is a switch button part. This switch button part 7 has a first switch button 7a for turning on / off the power supply and blinking the LED 6 and a second switch button 7b for blinking an electric light on the base part 7c. It is a bulge.

A protrusion 8 for pushing down push buttons of the first and second switches, which will be described later, is formed below the switch buttons 7a and 7b so as to be located at substantially the same position as the bottom surface of the base portion 7c. Also, these switch buttons 7a and 7b have a resilience to return to their original state after being pushed down due to their elasticity.

SW1 is a first switch for turning on / off the power supply and blinking the LED 6, and SW2 is a second switch for blinking the electric lamp. These switches SW1 and SW2 are lock type push switches which maintain the switched state when the push button 9 for switching the state is pushed down, and are fixed to the printed circuit board 5.

Since the projections 8 of the first and second switch buttons 7a and 7b and the push button 9 of the first and second switches SW1 and SW2 are configured to be in close proximity to each other, these switches When the buttons 7a and 7b are pressed down, the push buttons 9 of the switches SW1 and SW2 are pressed down by the protrusions 8 of the switch buttons 7a and 7b, and the first and second switches SW1 and SW2 are activated.

The reference numeral 10 holds a spiral battery spring 12 made of a conductive material that comes into contact with the negative electrode of the battery 11, and holds the printed circuit board 5 by holding portions 10 a provided on the upper and lower surfaces of the inner wall, respectively.
