Further, since a means for adjusting the force with which the presser body 44 is pressed by the presser spring 44 is provided, even if the interval is adjusted, the force with which the presser body 43 is pressed by the presser spring 44 can be maintained appropriately, and the spring retention is improved. The body 21 can be maintained in a fixed state with an appropriate force.

更に、押えバネ44を保持ケース45に内装したので、
押えバネ44が雨水等によって腐食したりする惧れが少
なく、押えバネ44による押え体43の好適な抑圧機能

Furthermore, since the presser spring 44 is housed inside the holding case 45,
There is little risk that the presser spring 44 will be corroded by rainwater or the like, and there is almost no risk that the appropriate suppressing function of the presser body 43 by the presser spring 44 will be impaired.
