Problems solved by technology
[0005] However, in this structure, since the tip of the rod must pass through the through hole and fit into the recess, the tip of the rod cannot be seen after the rod is inserted into the through hole.
Therefore, there is a problem that the operation when fitting the tip of the rod into the concave portion of the side wall is complicated.
In addition, since it is impossible to visually see whether the tip of the rod fits into the recess, it is undeniable that there is a possibility of deformation and damage when the tip of the rod is fitted into an inappropriate place.

Embodiment Construction
[0034] Next, an assembly method of a belt-type continuously variable transmission and a belt-type continuously variable transmission used in the method will be described in detail with reference to the drawings.
[0035] 1 is with the input shaft S 1 One-piece drive pulley. Drive pulley 1 according to input shaft S 1 The rotation about the axis O 1 Rotate for the center. Additionally, if figure 2 As shown, the drive pulley 1 has a fixed pulley 1a and a movable pulley 1b, and a hydraulic actuator assembly 1c is connected to the movable pulley 1b. Thus, the driving pulley 1 moves the movable pulley 1b along the input shaft S according to the hydraulic pressure supplied from the hydraulic actuator unit 1c. 1 By moving, the pulley width can be appropriately changed.
[0036] 2 is with the output shaft S 2 One-piece driven pulley. Driven pulley 2 with axis O 2 Rotate as the center, thus making the output shaft S 2 rotate. Additionally, if figure 2 As shown, the driven...

The invention provides a belt type power transmission device with excellent sound vibration performance, good endurance and easy assembly and an assembly method thereof. The assembly method includes a belt wheel member (Ps) between a housing (5) equipped with a rod (6) and a cover (7) matched with the housing (5). The belt wheel member (Ps) is provided with a guide member (4) of a belt (3) which penetrates through the rod (6) and is fixedly wound on two belt wheels (1, 2); the guide member (4) penetrates through the rod (6) to mount the member (Ps) on the housing (5); an auxiliary rod (8) is installed on the front end (6a) of the rod; then, the auxiliary rod (8) is inserted into a through hole (H1) on which the cover (7) is formed; the cover (7) is mounted on the housing (5); furthermore, in a state that the cover (7) is mounted on the housing (5), a sealing member (10) and a blocking member (9) are mounted in the through hole H1after dismounting the auxiliary rod (8) projected out the through hole (H1) from the front end (6a) of the rod.
Description
technical field [0001] The present invention relates to an assembly method of a belt type power transmission used, for example, in the manufacture of a belt type continuously variable transmission and a belt type power transmission used in the method. Background technique [0002] As a belt-type power transmission device, for example, a drive belt (an endless belt) wound on two pulleys is provided with a guide device for suppressing the sound vibration of the endless belt, and the guide device is passed through the belt. Install the oil supply pipe (rod) in the storage space, and fix the rod. (For example, refer to Patent Document 1) [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2005-121197 ( figure 1 ) [0004] In the prior art described above, a through hole (through hole) is formed on the side wall of the housing on which the concave portion is formed and on the side wall of the housing opposite thereto so as to be aligned with the concave po...
