In general, the traveling carriage 6 and the parking room frame 37 should not be made of a rigid body in order to reduce the size and weight, and should be designed to allow deflection, deformation, etc. to the extent that there is no problem with safety. Is desirable. However, the reaction force caused by pressing the power transmission roller 19 against the driven roller 22 of the parking room 8 is shown in FIG.
When the deflection of the parking room frame 37 or the deflection of the main frame 17 (FIG. 8) occurs as shown in FIG. 10B, the pressing force of the power transmission roller 19 against the driven roller 22 is insufficient. Therefore, the power transmission roller 19 and the driven roller 22

Is located above the rotation axis of the rotating body of the driving means, the contact points of the two rotating bodies are at positions deviated from the distal end surfaces in the approaching direction of separation from each other. The contact force at this contact acts in a direction orthogonal to the tangent of the two rotating bodies. This contact force generates a bending moment about the fulcrum of the support member that supports the rotating shaft of one of the rotating bodies. Then, elastic energy due to torsion is stored at the fulcrum of the support member. This elastic energy is used as a force (preload) for pressing the rotating body of the driven means against the rotating body of the driving means.

させる要因となる。Here, a case is considered in which the rotational force of the rotating body of the driving means is transmitted to the rotating body of the driven means in a state where the rotating body of the driving means and the rotating body of the driven means are engaged with each other under the preload. At this time, the reaction force of the transmission torque acts in the tangential direction of the two rotating bodies at the contact point. When the reaction force of the transmission torque acts on a fulcrum of a member that supports the rotating shaft of one of the rotating bodies, a bending moment is generated at the fulcrum. The bending moment due to the reaction force of the transmission torque deforms the supporting member in a direction in which the rotating body of the driven means pushes away the rotating body of the driving means (separates from each other),
This is a factor that lowers the adhesion and followability of the two rotating bodies at the contact points.

Then, the deformation of the support member due to an increase in the moment generated at the fulcrum due to the reaction force of the transmission torque is suppressed, and the followability between the two rotating bodies at the contact point is enhanced.

と回転防止爪34との係合を解くことができる。A rotation preventing claw 34 provided on a hook 33 is pressed against the driven gear 29. The hook 33 is a member whose one end is rotatably supported by the rotating shaft 33 a and has a shape along the outer peripheral surface of the driven gear 29. The urging means 35 such as a spring obtains the pressing force of the rotation preventing claw 34 against the driven gear 29. Normally, the rotation preventing claw 34 is engaged with the driven gear 29 to prevent the driven gear 29 from being inadvertently rotated.
However, by connecting the power transmission gear 26 to the driven gear 29, the hook 33 is pushed by the end of the movable frame 18 and rotates clockwise about the rotation shaft 33a in FIG.
And the rotation preventing claw 34 can be disengaged.

る。Further, a guide arm 30 is provided on a bracket 36 which is a member fixed to the parking room frame 37 and supports the rotating shaft 31. As shown in FIG. 5, the guide arm 30 is formed by bending a rod-like member into a substantially U-shape, and protruding a curved end portion toward the traveling vehicle 6. When the power transmission gear 26 is connected to the driven gear 29, the guide arm 30 engages with the guide receiving portion 18b of the movable frame 18. In addition, when the power is transmitted from the power transmission gear 26 to the driven gear 29, a large shift in the positional relationship between the gears (the vertical positional relationship in FIG. 5) due to the reaction force of the driving torque is prevented.

が位置するように配置してなるものである。Here, FIG. 1 shows an exaggerated feature of the power transmission device according to the embodiment of the present invention. As shown, the rotating shaft 31 of the driven gear 29 is supported by a bracket 36. The bracket 36 is fixed to the parking room frame 37. The parking room frame 37 is located below the rotation shaft 39 of the power transmission gear 26. The rotating shaft 31 supported by the bracket 36 is located above the rotating shaft 39 of the power transmission gear 26 by a height H. In other words, the power transmission gear
The rotation shafts 31 and 39 of the driven gear 26 and the driven gear 29 are separated from each other by a distance H in a direction orthogonal to the separation approach direction, and the driven gear
The rotation shaft 39 of the power transmission gear 26 is provided between the rotation shaft 31 of the
Are arranged so as to be positioned.

る。With this configuration, the following functions and effects can be obtained. First, since the rotating shaft 31 supported by the bracket 36 is located above the rotating shaft 39 of the power transmission gear 26 by the height H, the contact point (meshing point) C P between the power transmission gear 26 and the driven gear 29 is set. Is also a position deviating from the leading end surfaces in the direction approaching each other. Contact force in the contact point C P acts in a direction perpendicular to the tangent of the power transmission gear 26 and the driven gear 29. The contact force efficiently generates a bending moment about the parking room frame 37, which is a fulcrum of the bracket 36, and stores elastic energy due to torsion in the parking room frame 37. This elastic energy acts as a force (preload) for pressing the driven gear 29 against the power transmission gear 26.

モーメントＭ1 ＝Ｌt ×ｒ1 となる。Further, as shown in the figure, the rotating shaft 31 supported by the bracket 36 is located above the rotating shaft 39 of the power transmission gear 26 by a height H, so that the power transmission gear 26 and the driven gear 29 The contact point CP is located between the rotation shaft 31 of the driven gear 29 and the parking room frame 37. Then, the reaction force L t transmission torque at the time of transmitting the rotational force of the power transmission gear 26 to the driven gear 29, acts in the tangential direction of the two rotating bodies in contact C P. The reaction force of this transmission torque is
By acting on a fulcrum at which the parking chamber frame 37 also, the bending moment M 1 is generated in the parking chamber frame 37. In the figure, the distance r 1 from the fulcrum (the parking room frame 37) receiving the reaction force of the transmission torque to the action point (contact point CP )

との密着性、追従性を向上させる上で好ましい。The driven gear 29 with respect to the bending moment M 1, the power transmission gear 26 due to the reaction force L t of the transmitted torque
The parking room frame 37 is deformed in the direction of pushing away (separating from each other). Therefore, this is a factor that lowers the adhesion and followability between the power transmission gear 26 and the driven gear 29. In other words, towards the bending moment M 1 due to the reaction force L t of transmission torque is smaller is, the power transmission gear 26 and the driven gear 29
This is preferable in improving the adhesion and the follow-up property with the metal.

きくなることがわかる。[0028] According to the configuration of FIG. 2, the contact C P of the power transmission gear 26 and the driven gear 29 will be positioned further above the rotating shaft 31 of the driven gear 26. Also in FIG. 2, from the fulcrum for receiving a reaction force of the transmission torque (the parking chamber frame 37), the distance r 2 to the action point (contact point C P), s husband reaction force L t of transmission torque at the contact point C P schematic Is shown. FIG.
According to the arrangement, the distance r 2 is longer than the distance r 1 in FIG. 1. That is, even a reaction force L t of the driving torque at the contact point C P is the same size as in the FIG. 1, r 2> r 1
Thus, the bending moment M 2 applied to the parking room frame 37 =
Lt × r 2 > M 1 . Therefore, it can be seen that the amount of deformation of the parking room frame 37 is larger in the configuration of FIG. 2 than in the case of FIG.
