As a result, the pin 41 is separated from the first locking portion 18, and the slider portion 23 can move the slider with respect to the rail 5. In this state, the user can move the windscreen 7 up and down with respect to the rail 5. When the user stops pressing the windscreen 7 forward, the rotating portion 24 urged by the urging member 48 rotates from the release position to the locking position, and the pin 41 protrudes from the receiving hole 37. 1 It rushes into the locking portion 18. As a result, the position of the slider portion 23 with respect to the rail 5 is fixed. After that, when the user pushes the windscreen 7 downward, the rotating portion 24 moves from the second slide position to the first slide position with respect to the slider portion 23. As a result, the rotation of the rotating portion 24 with respect to the slider portion 23 is restricted, and the engagement between the second locking portion 25 and the first locking portion 18 is prevented from being unintentionally released.

Since the protrusion 69 is provided between the first end 53 and the second end 54 of the slot 51, the rotating portion 24 can be easily maintained at the first slide position or the second slide position. As a result, even if the windscreen 7 receives a load in a direction in which the windscreen 7 can slide with respect to the slider portion 23, the possibility that the windscreen 7 will move from a predetermined position is reduced. Further, the rattling of the slider portion 23 with respect to the rotating portion 24 is suppressed.

As shown in FIGS. 13 and 14, in the windscreen device 200 according to the second embodiment, the rail 201 extends in the vertical direction and the horizontal direction. Each outer surface 203 of the side portion 202 of the rail 201 is provided with a slot 204 extending vertically. Each slot 204 is a groove recessed in the side portion 202. The slider 205 has a rotating portion 206 and a slider portion 208 coupled to the rotating portion 206. The slider portion 208 is a pair of shaft members protruding from both side portions of the rotating portion 206 in a direction close to each other, and is arranged coaxially with each other. The slider portion 208 is slidably and rotatably supported with respect to the rail 201 by each slot 204. Further, as shown in FIG. 15, a pair of shaft members may be formed in which the slot 204 penetrates the side portion 202 in the left-right direction and the slider portion 208 protrudes from both side portions of the rotating portion 206 in opposite directions. ..

The slider unit 208 can slide up and down between the first position and the second position with respect to the slot 204. A protrusion 212 is provided between the first position and the second position of each slot 204. The protrusion 212 narrows the cross-sectional area of the slot 204. The protrusion 212 imparts resistance to the slider portion 208 when the slider portion 208 moves from one of the first position and the second position to the other. That is, the protrusion 212 keeps the slider portion 208 in the first or second position in the slot 204. A wind screen 214 is fixed to the front surface 213 of the rotating portion 206. One of the first locking portion 216 and the second locking portion 217 is a plurality of holes provided in one of the rail 201 and the rotating portion 206. Further, the other of the first locking portion 216 and the second locking portion 217 protrudes from the other of the rail 201 and the rotating portion 206 and can enter at least one of the holes. In the second embodiment, the first locking portion 216 is a hole provided in the rotating portion 206, and the second locking portion 217 protrudes from the rail 201.

When the slider portion 208 is arranged in the first position, the second position, or a predetermined position maintained by the protrusion 212 of the slot 204, the user rotates the rotating portion 206 to rotate the rotating portion 206 and the rail 201. The second locking portion 217 rushes into the first locking portion 216. As a result, the sliding movement of the slider unit 208 with respect to the rail 201 in the vertical direction is restricted. Further, when the user rotates the rotating portion 206 to separate the rotating portion 206 and the rail 201, the second locking portion 217 is disengaged from the first locking portion 216. As a result, the slider portion 208 can slide and move in the vertical direction with respect to the rail 201. The user can adjust the position of the windscreen 214 by sliding the slider portion 208 with respect to the rail 201. In the windscreen device 200, the shapes of the slider portion 208 and the rotating portion 206 are simplified, and the molding of the slider 205 can be facilitated.

Although the description of the specific embodiment is completed above, the present invention can be widely modified without being limited to the above embodiment.
