本考案は内燃機関における動弁用ブツシュロッドの改良
に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a bushing rod for a valve train in an internal combustion engine.
従来のこの種動弁用ブツシュロッドとしては、第１図に
示すように、金属管からなる本体１１０両側開口端部に
、外方に彎曲硬化面を有する別体の端金具を端構造部１
２として単に熔着しているに過ぎなかった。As shown in FIG. 1, a conventional bushing rod for a valve of this type has a separate end fitting having an outwardly curved hardened surface attached to an end structure 1 at both open ends of a main body 110 made of a metal tube.
2, it was simply welded together.
従って、機関運転時の上下往復動に伴って生ずるブツシ
ュロッド自体にかかる撓み振動により、長期の間に溶着
部１３での疲労が増太し、加えて溶着部１３における初
期溶着力の不足等と相俟って運転中にしばしば端構造部
１２の脱落事故を誘発する欠点があった。Therefore, the fatigue in the welded part 13 increases over a long period of time due to the bending vibration applied to the bushing rod itself caused by the vertical and reciprocating motion during engine operation. This has the disadvantage that the end structure 12 often falls off during operation.
本考案はこのような従来の欠点を除去したものテ、機関

機関運転中での端構造部の脱落成は首下での亀裂、損傷
の事故防止を計るようにしたものである。The present invention eliminates these conventional drawbacks, and effectively damps and absorbs the bending vibrations applied to the bushing rod itself that occur as the bushing rod reciprocates up and down during engine operation, thereby maintaining the welded area for a long period of time. Alternatively, the fatigue under the neck of the end structure is reduced, and if the end structure falls off during engine operation due to such fatigue, it is designed to prevent accidents such as cracks and damage under the neck. It is.
以下本考案の一実施例を図面について詳細に説明する。An embodiment of the present invention will be described in detail below with reference to the drawings.

により取付けられる。Fig. 2 is a partially cutaway plan view showing one embodiment of the bushing rod for a valve operating according to the present invention, in which 1 is the main body of the bushing rod made of a metal rod or metal tube, and 2 is a hardened surface curved outward. The end structure is attached to both ends of the main body 10 by welding and fixing.
３は本体１の端部附近でその内周壁面に予め圧嵌合され

着４せしめたものである。Reference numeral 3 denotes a metal cylindrical piece that is press-fitted in advance to the inner circumferential wall surface of the main body 1 near the end thereof, and its end is soldered 4 to the jaw 2a of the end structure 2.

労を極度に軽減せしめることができる。In the present invention, one end of the metal cylindrical piece 3 is press-fitted to the peripheral wall surface near the end of the main body 1 and soldered to the jaw 2a of the end structure 2, so that The bending vibrations applied to the bushing rod that occur as the bushing rod reciprocates up and down are effectively damped and absorbed by the frictional force caused by the press-fitting surface between the metal cylindrical piece 3 and the main body 1. This can extremely reduce the fatigue exerted on the area under the neck of the end structure 2.

る。Fig. 3 shows another embodiment of the bush rod of the present invention, in which the end structure 2 having a fitting engagement part is inserted into the inner circumferential wall surface of the main body 1 to center the main body 1 and the end structure 2. , in a bushing rod in which the jaw 2a of the end structure 2 is welded to the open end of the main body 1, the metal cylindrical piece 3 is press-fitted in advance to the outer peripheral wall surface near the end of the main body 1, and the end is attached to the end structure. The jaw part 2a of the part 2 is welded with solder 4, and its operation and effect are the same as in the case shown in FIG.

防止する効果あるものである。As explained in detail above, according to the present invention, the bending vibrations applied to the bushing rod are effectively damped and absorbed by the frictional force caused by the press-fitting between the metal cylinder piece and the main body. The falling type is effective in preventing accidents such as cracks and damage.
