PURPOSE:To enable to prevent turning of a pin in a reliable manner, by forming plate holes in grooves into which a pin is to be press fitted, and filling the inner spaces of the grooves and plate holes with a resin by injecting the resin from the grooves. CONSTITUTION:A pin 7 is extended through a rocker arm 6 and the opposite ends of the pin 7 are forced into respective groove 13. Here, it is preferable to insert the pin into the grooves 13 to such an extent that the peripheral surface of the pin 7 comes into contact with the botoom of the grooves 13. Then, a resin P is injected into the grooves 13. The resin P thus injected into the grooves 13 flows to the back of the pin 7 through a clearance H, so that turning of the pin 7 can be prevented positively. At the same time, since the plate holes 14 are also charged with the resin P, turning of the pin 7 can be prevented more positively. |
