Of the pair of stopper shafts 58 on the side of the water discharge pipe 14, one stopper shaft 58 on the lower side in the figure abuts on one stopper bolt 94 on the lower side in the figure, thereby The water pipe 14 is restricted in rotation there.
Here, the rotatable range of the water discharge pipe 14 is an angular range of 15 ° here.

  On the other hand, when the water discharge pipe 14 is rotated counterclockwise, the other stopper shaft 58 on the upper side in the figure on the water discharge pipe 14 side contacts the other stopper bolt 94 on the upper side in the figure. By contacting, the water discharge pipe 14 is restricted in rotation there. The range in which the water discharge pipe 14 can rotate at this time is also 15 °.

  That is, in the state shown in FIGS. 5 and 7, the stopper shaft 58 on the side of the water discharge pipe 14 does not come into contact with the stopper piece 86 as the first fixed stopper provided in the connecting member 70 with the rotation. It abuts only against the stopper bolt 94 as the second fixed stopper, and the rotation is restricted by them.

FIG. 8 shows a state in which the pair of stopper bolts 94 is in the state shown in FIG. 4, that is, when both of them are positioned in the downward movement position by the spacer 98 and neither of the pair of stopper bolts 94 acts as a stopper. This shows the action of the rotation restriction of the water pipe 14.
In this state, when the water discharge pipe 14 is rotated in the clockwise direction in the figure, of the pair of stopper shafts 58 on the water discharge pipe 14 side, the lower stopper shaft 58 in the figure is the corresponding stopper bolt 94 on the lower side in the figure.

The rotation range (rotation angle θ ₁ ) of the water discharge pipe 14 at this time is 75 ° here.
Note that θ ₁ represents the rotation angle when the water discharge pipe 14 is rotated most clockwise from the central position of the entire rotation range.

On the other hand, when the water discharge pipe 14 is rotated in the counterclockwise direction as indicated by the arrow in FIG. 8B, the stopper shaft 58 on the upper water discharge pipe 14 side in the figure again corresponds to the upper side in the corresponding figure. Passing through the stopper bolt 94, it comes into contact with the upper stopper surface 90 of the stopper piece 86 in the figure, and here the rotation of the water discharge pipe 14 in the counterclockwise direction in FIG.
The rotation angle from the central position of the water discharge pipe 14 at this time is also θ ₁ (θ ₁ is 75 ° here).

FIG. 9 shows the effect of restricting the rotation of the water discharge pipe 14 when the pair of stopper bolts 94 is in the state shown in FIG.
In this state, when the water discharge pipe 14 is rotated in the clockwise direction in FIG. 9, the stopper shaft 58 of the lower water discharge pipe 14 in the figure passes through the corresponding stopper bolt 94 on the lower side in the figure, and the stopper Abutting against the stopper surface 90 of the piece 86, the rotation of the water discharge pipe 14 is restricted there.
Rotation angle in this case is theta ₁ of 75 °.

On the contrary, when the water discharge pipe 14 is rotated counterclockwise in FIG. 9B, the upper stopper shaft 58 in FIG. 9 is in contact with the stopper bolt 94 in the upward movement position, that is, the stopper acting state. Therefore, the rotation of the water discharge pipe 14 is restricted.
At this time, the rotation angle θ ₂ from the center position (neutral position) of the water discharge pipe 14 is 15 ° here.
That is, in the state shown in FIG. 6, the water discharge pipe 14 can rotate by 75 ° of θ ₁ in the clockwise direction in FIG. 9, and can rotate by 15 ° of θ _{2 in} the counterclockwise rotation in the reverse direction. Is possible.

  However, in this embodiment, any one of the pair of stopper bolts 94 does not act as a stopper as shown in FIGS. 5 and 7, and only one of the stopper bolts 94 acts as a stopper. use.

Although not shown in the drawing, the stopper bolt 94 on the left side in FIG. 6 is removed by screwing the spacer 98 up to the full position with the spacer 98 removed, and the spacer 98 is mounted between the stopper bolt 94 on the right side and the base 68. As a state, when the right stopper bolt 94 is positioned at the downward movement position, the water discharge pipe 14 is allowed to rotate clockwise in FIG. 9 by 15 ° of θ _{2 and in} the counterclockwise direction in the reverse direction. Can be rotated up to 75 ° of θ ₁ .
