該摘子７の長手方向に沿つて凹設される。 A single knob 7 extending in the diameter direction is integrally provided on the upper surface of the enlarged head 6, and the upper surface of the enlarged head 6 remaining on both sides of the knob 7 is provided with a pair of fingertip support parts 8,
It is considered to be 8. Further, the knob 7 is formed such that the wall thickness at both ends in the longitudinal direction increases toward the outside in the longitudinal direction, and the knob 7 has an opening only at its upper end surface, and a coin can be engaged with the knob 7. A half-moon-shaped coin engaging groove 9 is recessed along the longitudinal direction of the knob 7.

ビス４に強力な締付け力を加えることができる。 Next, to explain the operation of this embodiment, when screwing the screw 4 into the cap body 1 to attach the transparent shield plate 3, first touch the knob 7 with two fingertips, and then hold the knob 7 with the fingertips. By rotating the knob 7 while pressing the pair of fingertip support parts 8, 8, the threaded part 5 can be screwed into a predetermined screw hole of the cap body 1 without turning idly. The two fingertips grip both sides of the knob 7 to prevent it from slipping.
A strong tightening force can be applied to the screw 4.
また、摘子７のコイン係合溝９にコインを嵌め

い。 As described above, according to the present invention, the screw is formed by forming a pair of fingertip support parts on the upper surface of the circular enlarged head and a single knob that protrudes from between the two fingertip support parts and extends in the diametrical direction. In the above-mentioned knob, a roughly half-moon-shaped coin engagement groove is formed along the longitudinal direction of the knob and is open only on the upper end surface of the knob and can be engaged with a coin. By simply engaging a coin in the engagement groove, you can apply a strong tightening force to the screw without using any tools such as a screwdriver, which is extremely convenient. There is no need to increase the size of the picker itself.

の強度アツプを図ることができる。 In particular, since the coin engaging groove is formed in the knob itself along the shape of the elongated knob extending in the diametrical direction of the circular enlarged head, the coin engaging groove is formed in the enlarged head in order to form the engagement groove. There is no need to specially change or complicate the shape of the screw, and the overall shape of the screw can be configured simply. Moreover, since the coin engaging groove is formed in the knob, which is relatively tall, it is possible to secure a sufficient depth of the groove without making the large head of the screw itself thick in the axial direction. can. Moreover, the approximately half-moon-shaped coin engaging groove can always match the concavely curved bottom surface to the arcuate outer peripheral surface of the coin, and furthermore, as the bottom wall of the groove approaches both longitudinal ends of the knob, By being raised, it is possible to increase the strength of both longitudinal end walls of the knob, which are likely to collide with other objects.

きる。 Furthermore, the knob is formed such that the wall thickness at both ends in the longitudinal direction increases toward the outside in the longitudinal direction, so that the picking surface of the knob is concave and fits well with the fingertip. It is possible to prevent slippage, and it is possible to apply even stronger tightening force to the screw.
Furthermore, by increasing the thickness of both ends of the knob in the longitudinal direction, the strength of both ends can be further increased.
