【発明の実施の形態】
図１〜３は、本発明の実施の形態の１例を示している。尚、本発明の特徴は、トロイダル型無段変速機の入力軸１５ｂに、入力側ディスク２Ａ及び押圧装置９等を組み付けた構造をユニット化して、組み付け治具３４によりこれら各部品１５ｂ、２Ａ、９同士が不用意に分離する事を防止した点にある。その他の部分の構造及び作用に就いては、前述した従来構造と同様である為、重複する図示及び説明を省略若しくは簡略にし、以下、本発明の特徴部分を中心に説明する。 0025
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 to 3 show an example of an embodiment of the present invention. The feature of the present invention is that the structure in which the input side disc 2A, the pressing device 9 and the like are assembled to the input shaft 15b of the toroidal continuously variable transmission is unitized, and these parts 15b , 2A, are provided by the assembling jig 34. The point is that the 9s are prevented from being inadvertently separated from each other. Since the structure and operation of other parts are the same as those of the conventional structure described above, overlapping illustrations and explanations will be omitted or simplified, and the feature parts of the present invention will be mainly described below.

上記両ボールスプライン溝４６、４７同士の間に所定数のボール４８、４８を挿入したならば、次いで、上記押圧装置９のカム板１０を回転させて、上記入力側ディスク２Ａを上記入力軸１５ｂの軸方向に移動させ、前記係止溝７７の内径側開口を前記小径部６６に開口させる。そして、この小径部６６を通じて前記ディスク側止め輪６４を、上記入力側ディスク２Ａの内周面の内側面２ａ寄り部分に内嵌し、上記ディスク側止め輪６４と上記係止溝７７とを整合させる。そして、このディスク側止め輪６４自身の弾性により、このディスク側止め輪６４と上記係止溝７７とを係合させる。この様にして係止溝７７にディスク側止め輪６４を装着したならば、上記カム板１０を逆方向に（或はそのままの方向に更に）回転させて、上記各ローラ１２、１２を前記駆動側、被駆動側両カム面１３、１４の凹部に当接させる。この結果、上記係止溝７７が上記小径部６６から外れ、上記ディスク側止め輪６４がこの係止溝７７から抜け出る事がなくなる。この様にして各部品１５ｂ、６３、１０、２Ａ、１２、１１を組み立てたならば、各部の寸法並びに作動状態を確認し、これら寸法並びに作動状態が適正であれば、前記組み付け用治具３４により、上記各部品１５ｂ、６３、１０、２Ａ、１２、１１を、不用意に分離しない様に結合する。尚、この際、上記各ローラ１２、１２は、前記駆動側、被駆動側両カム面１３、１４の底部に位置させて、上記カム板１０と入力側ディスク２Ａとを再接近させておく。 After inserting a predetermined number of balls 48, 48 between the two ball spline grooves 46, 47, the cam plate 10 of the pressing device 9 is then rotated to insert the input side disc 2A into the input shaft 15b. The inner diameter side opening of the locking groove 77 is opened in the small diameter portion 66. Then, the disk-side retaining ring 64 is fitted into the inner peripheral surface of the input-side disk 2A near the inner side surface 2a through the small-diameter portion 66, and the disk-side retaining ring 64 and the locking groove 77 are aligned. Let me. Then, the elasticity of the disc-side retaining ring 64 itself causes the disc-side retaining ring 64 to engage with the locking groove 77. When the disc side retaining ring 64 is attached to the locking groove 77 in this way, the cam plate 10 is rotated in the opposite direction (or further in the same direction) to drive the rollers 12 and 12 in the same direction. The cam surfaces 13 and 14 on both the side and the driven side are brought into contact with each other. As a result, the engagement groove 77 is disengaged from the small diameter portion 66, the disc-side snap ring 64 that is eliminated exiting from the locking groove 77. When the parts 15b, 63, 10, 2A, 12, and 11 are assembled in this way, the dimensions and operating conditions of each part are confirmed, and if these dimensions and operating conditions are appropriate, the assembly jig 34 is used. As a result, the above-mentioned parts 15b, 63, 10, 2A, 12 and 11 are joined so as not to be inadvertently separated. At this time, the rollers 12 and 12 are positioned at the bottoms of both the driven side and driven side cam surfaces 13 and 14, and the cam plate 10 and the input side disc 2A are brought close to each other again.
