Apparatus for connection of operating rod

An apparatus for rotatably connecting an operating rod to a fitting hole, which apparatus comprises:

• a main connection member made of a synthetic resin and integrally provided with a head portion having retention means provided thereon for retaining said operating rod and with an engaging leg portion which extends perpendicularly from the lower side of said head portion, which leg portion has an engaging stepped portion provided on the peripheral surface thereof and contains a hollow portion therein;
• and
• an insertion member made of a metallic material, provided with a female screw hole adapted for helical union with a male screw formed on the peripheral surface of the operating rod, and assembled with said main connection member;
• said main connection member having an opening formed in the head portion thereof to a depth enough for communication with the hollow portion of said engaging leg portion;
• whereby the connection of the operating rod to the operating member is accomplished by fitting said insertion member into said opening, helically joining said operating rod to the female screw hole of said insertion member and, at the same time, causing the operating rod to be retained in position by said retention means provided on the head portion of the main connection member, and pushing said engaging leg portion through the fitting hole in said operating member into rotatable engagement with the operating member.
