Claims

[Scope of utility model registration request]

An on-off valve that opens and closes the intake and exhaust holes is slidably inserted into the cylinder head of an internal combustion engine, and a retainer is attached to the upper end of the on-off valve via a two-piece rotor. A mounting device for installing a retainer of an on-off valve device between a valve stem and a retainer of an on-off valve, in which a valve spring is compressed and interposed therebetween, and the on-off valve is opened and closed by the elasticity of the valve spring, A hollow mounting body having a conical guide surface on the inner circumferential surface of the bottom for raising and holding a tilted two-piece rotor, and a recess that is integrally connected to the lower end of the mounting body and into which a retainer is inserted; a punch whose inner circumferential surface of the concave portion is formed into a conical shape 1, and a through hole formed in the center through which the slanted cotter can pass; and a cylindrical pressing member which is fitted and fixed into the mounting main body and press-fits the cotter. parts and
A cotter expansion rod is slidably inserted into the pressing member and has a substantially hemispherical lower end surface, and a cotter expansion rod is compressed and interposed between the cotter expansion rod and the mounting body to press the cotter expansion rod downward. A cotter mounting device for an opening/closing valve device, characterized in that it is configured with a return spring that moves.
