PURPOSE:To prevent removal of an abrasion-resistant member from a recessed part at the time of assembling or maintenance for a mechanical parts by providing an interval between the recessed part and the abrasion-resistant member, and putting a stopper having a resiliency to the thickness of the interval inside the interval to be deformed by the resiliency. CONSTITUTION:A recessed part 2a is formed in a valve bridge 1a at a part applied to a locker arm, and an interval S is provided to the recessed part 2a, where an abrasion-resistant member 3a is inserted. A stopper 4a having a resiliency to the thickness of the interval is put to be deformed by the resiliency. The abrasion-resistant member 3a is thus fixed to the recessed part 2a by stretching action of the stopper 4a by a restoring force from the resiliency deformation. The abrasion-resistant member 3a is thus fixed to the recessed part 2a by the stopper 4a, thereby its removal at the time of assembling work can be prevented. |
