このように構成された本発明の請求項１に係る溶接構造は、前記連結レバー部材の挿通孔の前記ピン部材挿入側入口部外周縁に、凹設形成された環状の溝部へ、溶接のスパッタが溜まり、外部への飛散が防止されると共に、周縁の部位の変形が抑制される。   The welding structure according to claim 1 of the present invention configured as described above is formed by welding spattering into an annular groove formed in a recess in the outer peripheral edge of the pin member insertion side inlet of the insertion hole of the connecting lever member. Is accumulated, and scattering to the outside is prevented, and deformation of the peripheral portion is suppressed.

以下、発明を実施するための最良の形態を実施例に基づいて説明する。   Hereinafter, the best mode for carrying out the invention will be described based on examples.

まず、構成から説明すると、この実施の形態の溶接構造は、図２に示すようなトルクセンサ装置５によってシフトレバー操作力が、検出されて、操作力をアシストする自動変速機の変速操作装置に用いられるものである。   First, in terms of configuration, the welding structure of this embodiment is a shift operation device for an automatic transmission that assists the operation force when a shift lever operation force is detected by a torque sensor device 5 as shown in FIG. It is used.

このトルクセンサ装置５には、一対のボールベアリング６，６によって回動自在に支持された回動軸部材７が設けられている。   The torque sensor device 5 is provided with a rotating shaft member 7 that is rotatably supported by a pair of ball bearings 6 and 6.

この回動軸部材７には、トルクセンサ本体８が設けられていると共に、一端部７ａにナット部材９によってインプットレバー部材１０が、固定されている。   The rotating shaft member 7 is provided with a torque sensor body 8 and an input lever member 10 is fixed to the one end portion 7a by a nut member 9.

また、この回動軸部材７の他端部７ｂには、ナット部材１２によって連結レバー部材としてのアウトプットレバー部材１１が固定されている。   Further, an output lever member 11 as a connecting lever member is fixed to the other end portion 7 b of the rotating shaft member 7 by a nut member 12.

そして、インプットレバー部材１０からの入力が、このアウトプットレバー部材１１へ伝達される際に、捻れ力が電気的な信号に変換されることによって、トルクが検出されるように構成されている。   When the input from the input lever member 10 is transmitted to the output lever member 11, the torsional force is converted into an electrical signal so that the torque is detected.

図１乃至図５は、本発明の実施例１に係る自動変速機の変速操作装置の連結レバー部材とピン部材との溶接構造を説明する図である。   FIGS. 1 to 5 are views for explaining a welding structure between a connecting lever member and a pin member of a shift operation device for an automatic transmission according to a first embodiment of the present invention.

本実施例１では、アウトプットレバー部材１１が、金属製の板状を呈するレバー本体１１ａの両側面間を貫通して、前記ピン部材２の円柱状の基軸部２ａが、挿通可能な挿通孔１１ｂが設けられている。   In the first embodiment, the output lever member 11 penetrates between both side surfaces of the lever main body 11a having a metal plate shape, and the insertion hole 11b through which the cylindrical base shaft portion 2a of the pin member 2 can be inserted. Is provided.

この挿通孔１１ｂの前記ピン部材２が挿入される側の入口部外周縁には、図１に示すように環状の溝部１１ｄが、全周に渡って、このアウトプットレバー部材１１の側面部１１ｅよりも一段低くなるように、段状に凹設形成されている。   As shown in FIG. 1, an annular groove 11d is formed on the outer peripheral edge of the inlet portion of the insertion hole 11b on the side where the pin member 2 is inserted, from the side surface portion 11e of the output lever member 11 over the entire circumference. Is also formed in a stepped shape so as to be one step lower.

そして、この挿通孔１１ｂの内周面１１ｃと、前記基軸部２ａの外周面２ｂとの間を溶接することにより、前記アウトプットレバー部材１１に、このピン部材２を固着させるように構成されている。   The pin member 2 is fixed to the output lever member 11 by welding between the inner peripheral surface 11c of the insertion hole 11b and the outer peripheral surface 2b of the base shaft portion 2a. .

更に、この実施例１では、前記筒部２ｃと同一軸上に一体に形成されて、前記挿通孔１１ｂの径ｄ１よりも大径の筒部２ｃが、一定の外径寸法ｄ３を有して設けられている。   Furthermore, in the first embodiment, the cylindrical portion 2c that is integrally formed on the same axis as the cylindrical portion 2c and has a larger diameter than the diameter d1 of the insertion hole 11b has a constant outer diameter d3. Is provided.

この筒部２ｃには、図示省略の自動変速機に連結されるリンケージ（図６中符号３等参照）が連結されている。   A linkage (see reference numeral 3 in FIG. 6) connected to an automatic transmission (not shown) is connected to the cylindrical portion 2c.

そして、この実施例１の前記溝部１１ｄの外形寸法ｄ２は、前記筒部２ｃの径ｄ３よりも、小径となるように構成されている。   And the external dimension d2 of the said groove part 11d of this Example 1 is comprised so that it may be smaller than the diameter d3 of the said cylinder part 2c.

このため、図１に示すように、前記ピン部材２の基軸部２ａを前記挿通孔１１ｂに挿通した状態で、前記側面部１１ｅに、前記筒部２ｃの端面２ｄを当接させることにより、この溝部１１ｄが前記ピン部材２によって覆われて、前記溝部１１ｄによって、空隙１３がリング状に形成されるように構成されている。   For this reason, as shown in FIG. 1, the end surface 2d of the cylindrical portion 2c is brought into contact with the side surface portion 11e while the base shaft portion 2a of the pin member 2 is inserted into the insertion hole 11b. The groove part 11d is covered with the pin member 2, and the gap 13 is formed in a ring shape by the groove part 11d.

次に、この実施例１の自動変速機の変速操作装置の連結レバー部材とピン部材との溶接構造の作用について説明する。   Next, the operation of the welding structure between the connecting lever member and the pin member of the shift operation device for the automatic transmission according to the first embodiment will be described.

この実施例１では、前記アウトプットレバー部材１１と、前記ピン部材２との間の溶接が行われる際、前記アウトプットレバー部材１１の挿通孔１１ｂの前記ピン部材２が挿入される側の入口部外周縁に、凹設形成された環状の溝部１１ｄと、前記ピン部材２の筒部２ｃ端面２ｄとの間に形成されたリング状の空隙１３へ、溶接のスパッタが溜まる。   In the first embodiment, when welding is performed between the output lever member 11 and the pin member 2, the outside of the inlet portion on the side where the pin member 2 of the insertion hole 11 b of the output lever member 11 is inserted. Sputtering of welding accumulates in the ring-shaped gap 13 formed between the annular groove portion 11d formed in a recessed manner on the periphery and the end surface 2d of the cylindrical portion 2c of the pin member 2.

また、前記ピン部材２の基軸部２ａが、前記挿通孔１１ｂに挿通された状態で、前記側面部１１ｅに、前記筒部２ｃの端面２ｄが当接されて、この溝部１１ｄが前記ピン部材２によって覆われて、外部（例えば、図１中部位Ａ）へのスパッタの飛散が防止されると共に、周縁の部位の変形が抑制される。   In addition, in a state where the base shaft portion 2a of the pin member 2 is inserted through the insertion hole 11b, the end surface 2d of the cylindrical portion 2c is brought into contact with the side surface portion 11e, and the groove portion 11d is formed into the pin member 2. The spattering to the outside (for example, site A in FIG. 1) is prevented, and deformation of the peripheral site is suppressed.

更に、この実施例１では、前記空隙１３によって、外部へのスパッタの飛散が防止されるので、前記端面２ｄと、アウトプットレバー部材１１の側面部１１ｅとの間の重複代が少なくても、外部へスパッタが飛散する事が無い。   Furthermore, in the first embodiment, since the spatter of the spatter to the outside is prevented by the gap 13, even if there is little overlap margin between the end surface 2d and the side surface portion 11e of the output lever member 11, the external space Spatter does not scatter.

このため、前記基軸部２ａの径ｄ１を比較的大きく設定出来、溶接される前記挿通孔１１ｂの内周面１１ｃと、前記基軸部２ａの外周面２ｂとの間の周上長さを増大させることが出来る。   For this reason, the diameter d1 of the base shaft portion 2a can be set relatively large, and the circumferential length between the inner peripheral surface 11c of the insertion hole 11b to be welded and the outer peripheral surface 2b of the base shaft portion 2a is increased. I can do it.

従って、更に、溶接量を増大させて、前記アウトプットレバー部材１１とピン部材２との結合強度を高めることができる。   Therefore, the amount of welding can be further increased, and the coupling strength between the output lever member 11 and the pin member 2 can be increased.

以上、この発明の実施の形態を図面により詳述してきたが、具体的な構成は、この実施の形態に限らず、この発明の要旨を逸脱しない範囲の設計の変更等があってもこの発明に含まれる。   The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention, include.

例えば、前記実施の形態の溶接構造では、連結レバー部材としてのアウトプットレバー部材１１とピン部材２との結合部分に適用したものを示して説明してきたが、特にこれに限らず、例えば、連結レバー部材としてのインプットレバー部材１０と、このインプットレバー部材１０に固着されるピン部材との結合部分に適用したもの等、連結レバー部材とピン部材との間が、溶接により固着されるものであるならば、形状、数量及び材質が特に限定されるものではない。   For example, in the welded structure of the above-described embodiment, the description has been made by showing what is applied to the connecting portion between the output lever member 11 as the connecting lever member and the pin member 2, but the invention is not limited to this. If the connection lever member and the pin member are fixed by welding, such as those applied to the connecting portion between the input lever member 10 as a member and the pin member fixed to the input lever member 10 For example, the shape, quantity and material are not particularly limited.
