[1.1. Description of the configuration of the sun plate stopper 4]
As shown in FIG. 2A, the sun plate stopper 4 is rotatably attached to the back surface of the sun plate 1. More specifically, the sun plate stopper 4 includes a plate-like base 41, a plate-like supported portion 42 supported by the sun plate stopper support 5, and the sun plate stopper 4 rotating on the back surface of the sun plate 1. And a fixed portion 43 for attachment, and the supported portion 42 has a shape extending from one end of the base portion 41 at a substantially right angle.

  The fixing portion 43 has a U-shaped cross section, one wall surface 43a is fixed to the back surface of the sun plate 1 by welding or the like, and the base portion 41 is rotatably attached to the other wall surface 43b. In other words, a circular through hole 43d is formed in the other wall surface 43b of the fixing portion 43, and the base portion 41 is positioned between the two wall surfaces 43a and 43b of the fixing portion 43, and the through hole 43d of the fixing portion 43 that communicates therewith. And a pin 44 is inserted through the circular through hole 41 a of the base 41. The tip of the pin 44 is inserted into a through hole 43e formed in one wall surface 43a of the fixing portion 43 and fixed by welding or the like. As a result, the connecting portion 43c is positioned on the locus when the base portion 41 is rotated, and can contact the rotating base portion 41 to stop its rotation. In addition, the center point of the through-hole 41a of the base 41 corresponds to the attachment point in the claims. Moreover, the connection part 43c corresponds to the 1st rotation prevention part and the 2nd rotation prevention part of a claim.

  Further, as shown in FIG. 2B, the base 41 has a base portion that is more than the weight of the side (first side portion) 41c from which the supported portion 42 extends out of the portions on both sides of the attachment point 41b of the base 41. 41d on the opposite side (second side, hatched portion in FIG. 2 (b)) of the portion on both sides of the attachment point 41b of 41 from the side where the supported portion 42 extends is greater. .

  In addition, the base 41 is formed with a notch 41e that can include a connecting portion 43c that connects the two wall surfaces 43a and 43b of the fixed portion 43 during rotation. The depth dimension of the notch 41e is such that when the sun plate 1 is in a vertical state, the first side portion 41c is located vertically below the attachment point 41b and faces the sun plate stop support 5 (opposite state). ) Is rotated 90 degrees in one direction and can be changed until it does not face the sun plate support 5 (non-opposing state).

  Further, as shown in FIG. 2 (c), the base 41 has a base 41 more than the weight of the side (third side) 41f having the opening of the notch 41e among the portions on both sides of the attachment point 41b of the base 41. Of the portions on both sides of the attachment point 41b, the weight of the side 41g opposite to the third side portion 41f (fourth side portion, shaded portion in FIG. 2C) is larger.

The second side portion 41d of the base portion 41 corresponds to the first biasing portion in the claims, and the fourth side portion 41g of the base portion 41 corresponds to the second biasing portion in the claims.
[1.2. Description of the configuration of the sun plate support 5]
As shown in FIG. 1, the sun plate support 5 is formed in a plate shape and is attached to the end face of the railway vehicle in a horizontal state. More specifically, the sun plate stopper support 5 is disposed at a position facing the supported portion 42 of the sun plate stopper 4 positioned vertically below the attachment point 41b when the sun plate 1 is in the vertical state. (See FIG. 2 (c)). Thus, when the sun plate 1 is in the vertical state, the sun plate stop support 5 can hold the sun plate 1 in the vertical state by supporting the supported portion 42 of the opposing sun plate stop 4.

  Further, the sun plate stopper support 5 is disposed at a position facing the supported portion 42 of the sun plate stopper 4 located on the side of the attachment point 41b when the sun plate 1 is in a horizontal state (FIG. 2 ( a)). That is, the sun plate stopper support 5 is positioned on a locus during rotation of the base 41 of the sun plate stopper 4 when the sun plate 1 is in a horizontal state. Thus, when the sun plate 1 is in a horizontal state, the sun plate stop support 5 cooperates with the connecting portion 43c of the fixing portion 43 to rotate the sun plate stop 4 due to vibration during travel of the railway vehicle. Can be blocked. Note that the sun plate support 5 corresponds to the third rotation blocking portion of the claims.

[3. Effects of the embodiment]
(1) As described above, according to the holding structure 3 of the present embodiment, the following operational effects can be obtained.
(1-1) As illustrated in FIG. 2B, when the sun plate 1 is changed from the horizontal state to the vertical state, the second side portion 41 d of the base portion 41 of the sun plate stopper 4 is supported by the supported portion 42. The rotation of the sun plate stopper 4 is urged by its own weight so as to be in a non-opposing state, and the connected portion 43c of the fixing portion 43 is not opposed to the supported portion 42 by the urging force of the second side portion 41d of the base 41. In this state, the base 41 of the sun plate stopper 4 is prevented from rotating against the urging force of the second side portion 41d.

  That is, the second side portion 41d of the base portion 41 of the sun plate stopper 4 and the connecting portion 43c of the fixing portion 43 of the sun plate stopper 4 cooperate to bring the supported portion 42 of the sun plate stopper 4 into a non-opposing state. Thus, the sun plate stopper 4 is prevented from rotating and the supported portion 42 is prevented from being opposed. Therefore, even if the sun plate 1 is mistakenly changed from the horizontal state to the vertical state, the sun plate stop support 5 does not support the supported portion 42 of the sun plate stop 4 and the sun plate 1 is moved from the vertical state to the horizontal state. You can manually return to the state.

  (1-2) On the other hand, when it is desired to hold the sun plate 1 in a vertical state, the sun plate stopper 4 may be manually rotated to bring the supported portion 42 of the sun plate stopper 4 into an opposing state (FIG. 2 ( c)). Then, the fourth side portion 41g of the base portion 41 of the sun plate stopper 4 urges the rotation of the base portion 41 of the sun plate stopper 4 so that the supported portion 42 of the sun plate stopper 4 changes from the opposed state to the non-opposed state. When the supported portion 42 is urged from the opposed state to the non-opposed state by the urging force of the fourth side portion 41g of the base portion 41, the connecting portion 43c of the fixing portion 43 resists the urging force of the fourth side portion 41g. Thus, the rotation of the sun plate stopper 4 is prevented.

  In other words, the fourth side portion 41g of the base portion 41 of the sun plate stopper 4 and the connecting portion 43c of the fixing portion 43 of the sun plate stopper 4 cooperate to rotate the sun plate stopper 4 so that the supported portion is in an opposing state. 42 prevents the non-opposing state 42, and the sun plate stopper support 5 supports the supported portion 42 of the sun plate stopper 4.

  Therefore, even if the sun plate 1 is mistakenly changed from the horizontal state to the vertical state, the sun plate 1 can be reliably returned to the horizontal state, and the sun plate 1 can be held in the vertical state when necessary.

  (2) Also, according to the holding structure 3 of the present embodiment, the connecting portion 43c of the fixing portion 43 of the sun plate stopper 4 is located on the locus of rotation of the base portion 41, so the base portion of the rotating sun plate stopper 4 It can contact | abut 41 and can stop the rotation (refer FIG.2 (b) * (c)). That is, the rotation of the sun plate stopper 4 is reliably prevented against the urging force by the second side portion 41 d of the base portion 41 of the sun plate stopper 4 and the urging force by the fourth side portion 41 g of the base portion 41 of the sun plate stopper 4. be able to.

  (3) Further, according to the holding structure 3 of the present embodiment, the second side portion 41d as the first biasing portion and the fourth side portion 41g as the second biasing portion are part of the sun plate stopper 4. Since the rotation of the sun plate stopper 4 is urged by its own weight (see FIGS. 2B and 2C), the first urging portion and the second urging portion are made of, for example, a spring using a spring or the like. The number of parts can be reduced and the manufacturing cost can be reduced as compared with the case where the stopper 4 is configured separately.

  (4) Moreover, according to the holding structure 3 of the present embodiment, the supported portion of the sun plate stopper 4 is located on the side of the attachment point 41b when the sun plate stopper 5 is in the horizontal state. Since the sun plate 1 is positioned on the locus of rotation of the base 41 of the sun plate stopper 4 when the sun plate 1 is in the horizontal state (see FIG. 2A), the sun plate 1 is horizontal. In the state, in cooperation with the connecting portion 43c of the fixing portion 43 (see FIG. 2 (b)), the rotation of the sun plate stopper 4 due to vibration during traveling of the railway vehicle can be reliably prevented.

[4. Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

(1) With respect to the attachment point 41b, which is a point that rotatably supports the base portion 41 of the sun plate stopper 4 with respect to the fixing portion 43 fixed to the back surface of the sun plate 1, the sun plate 1 is in a vertical state. When the supported portion 42 of the sun plate stopper 4 is in an opposed state, both sides (third side portion 41f and fourth side portion 41g) of the attachment point 41b are balanced, and the sun plate 1 is in a vertical state. In some cases, when the supported portion 42 of the sun plate stopper 4 is in a non-opposing state, both sides (first side portion 41c and second side portion 41d) of the attachment point 41b are set to be balanced points. Also good.

If comprised in this way, there exist the following effects.
(1-1) That is, when the sun plate 1 is changed from the horizontal state to the vertical state, both sides of the attachment points 41b of the sun plate stopper 4 (first Since the one side portion 41c and the second side portion 41d) are balanced, the base portion 41 of the sun plate stopper 4 does not rotate by its own weight, and the supported portion 42 of the sun plate stopper 4 and the sun plate stopper support 5 face each other. It will not be. Therefore, even if the sun plate 1 is mistakenly changed from the horizontal state to the vertical state, the sun plate stop support 5 does not support the supported portion 42 of the sun plate stop 4 and the sun plate 1 is moved from the vertical state to the horizontal state. You can manually return to the state.

(1-2) On the other hand, when it is desired to hold the sun plate 1 in a vertical state, the base portion 41 of the sun plate stopper 4 is manually rotated so that the supported portion 42 of the sun plate stopper 4 faces the sun plate stopper support 5. What is necessary is just to make it the opposing state. Then, when the supported portion 42 of the sun plate stopper 4 is in an opposing state, both sides (the third side portion 41f and the fourth side portion 41g) of the attachment point 41b of the sun plate stopper 4 are balanced. The base portion 41 does not rotate by its own weight, and the sun plate stopper support 5 supports the supported portion 42 of the sun plate stopper 4.

  Therefore, even if the sun plate 1 is mistakenly changed from the horizontal state to the vertical state, the sun plate 1 can be reliably returned to the horizontal state, and the sun plate 1 can be held in the vertical state when necessary.
