Thereby, the portion between the nut 62 that is fixed to the fixing member 6 of the front plate 1 and the nut 63 is screwed, and the portion between the nut 63 and the pillar portion 61 is from the front in the notch 5a. The open part is inserted into the gap 5a. In this way, the front portion of the front plate 1 is provided with the notch 5a in which the front end of the front plate 1 is opened. Therefore, even in the state in which the nut 63 is screwed to the bolt 62 in the fixing member 6, the screw can be screwed to the bolt 62. The bolt 62 is inserted into the notch 5a.

Further, the notch 7b has a shape in which the width in the lateral direction (Y direction) is wide from the base portion to the front end on the front side which is opened. In other words, the edge portion of the fork plate 5 constituting the notch 7b is widened from the base portion in the notch 7b to the front end at the front side. Thereby, the bolt 62 between the nut 63 and the pillar portion 61 is easily inserted into the cutout 7b from the front end side of the cutout 7b.

Next, as shown in FIG. 3(c), the nut 63 screwed to the bolt 62 is fastened toward the pillar portion 61 in a state in which the bolt 62 is inserted into the notch 5a. As a result, the fork plate 5 around the periphery of the notch 5a is sandwiched by the support portion 61 by the nut 63, and the front portion of the fork plate 5 is fixed to the front plate 1 through the fixing member 6. In (a) to (c) of FIG. 3, the width of the notch 5a (insertion portion) is smaller than the outer diameter of the nut 62 and the pillar portion 61 and larger than the outer diameter of the bolt 62.

When the front portion of the front plate 1 and the fork plate 5 are taken out, the order of the steps described in (a) to (c) of Fig. 3 may be reversed.

That is, in (c) of FIG. 3, the nut 63 is loosened toward the upper end of the bolt 62 so as not to fall off from the bolt 62. Thereby, as shown in FIG. 3(b), the nut 63 is separated from the fork plate 5. Then, the fork plate 5 is relatively moved (sliding) rearward with respect to the front plate 1. The result is as shown in the figure As shown in (a) of FIG. 3, the portion between the nut 63 and the pillar portion 61 in the bolt 62 in a state in which the nut 63 is screwed is separated from the notch 5a. Thereby, the portion between the nut 63 and the pillar portion 61 in the bolt 62 in which the nut 63 is screwed is released from the cutout 5a.

The outer diameter is small and larger than the outer diameter of the bolt 62. The nut 63 that has been fixed to the fixing member 6 of the front plate 1 in a state where the nut 63 has been screwed to the bolt 62 is inserted through the through hole 5b. Since the front through portion of one of the through holes 5b is larger than the outer shape of the nut 63, even if the nut 63 is screwed to the bolt 62 in the fixing member 6, the nut 63 can be inserted into the through hole. 5b.

Next, as shown in FIG. 4(b), the fork plate 5 is relatively moved (sliding) forward relative to the front plate 1, whereby the nut 63 in the bolt 62 in a state in which the nut 63 is screwed is The portion between the pillar portions 61 is inserted through the through hole 5b and the through portion.

Then, as shown in FIG. 4(c), the nut 63 screwed to the bolt 62 is fastened toward the pillar portion 61 in a state in which the bolt 62 is inserted through the through hole 5b. As a result, the fork plate 5 around the periphery of the through hole 5b is sandwiched by the support portion 61 by the nut 63, and the rear portion of the fork plate 5 is fixed to the front plate 1 through the fixing member 6.

When the front portion of the front plate 1 and the fork plate 5 are taken out, the order of the steps described in (a) to (c) of Fig. 4 may be reversed.

That is, in (c) of FIG. 4, the nut 63 is loosened toward the upper end of the bolt 62 so as not to fall off from the bolt 62. Thereby, as shown in FIG. 4(b), the nut 63 is divided from the fork plate 5 from. Then, the fork plate 5 is relatively moved (sliding) rearward with respect to the front plate 1. As a result, as shown in FIG. 4(a), the portion between the nut 63 and the pillar portion 61 of the bolt 62 in a state in which the nut 63 is screwed is inserted into the through portion of the through hole 5b. . Then, the fork plate 5 is separated from the front plate 1, whereby the portion between the nut 63 and the pillar portion 61 in the bolt 62 in which the nut 63 is screwed is released from the through portion of the through hole 5b. .

In this manner, the rear portion of the fork plate 5 can be easily taken out from the front plate 1.

Further, in the fork plate 5, the insertion portion of the two portions on the front sides of the both sides may be provided as a through hole which is closed at the front end of the front side instead of the notch 5a, and the two portions at the rear portions of the both sides are also provided. The insertion portion is provided as a notch in which the front end of the rear side is opened instead of the through hole 5b. Also with this configuration, the fork plate 5 can be easily taken out from the front plate 1 in the same manner.

(Structure in the vicinity of the opening portion 7a of the foot support plate 7)

The structure in the vicinity of the opening 7a of the leg support plate 7 will be described with reference to Figs. 5 and 6 . Fig. 5 is a view showing a mounting step of the rear plate 2 and the foot support plate 7. Fig. 6 is a cross-sectional view showing the vicinity of the opening portion 7a of the leg supporting plate 7.

As shown in FIGS. 5 and 6, the leg support plate 7 has a concave portion 7c that protrudes downward from the opening portion 7a on the back surface (the surface facing the rear plate 2). The recessed portion 7c is sandwiched by the nut 63 of the fixing member 6 and the pillar portion 61, whereby the leg supporting plate 7 and the rear plate 2 are fixed. The concave portion 7c extends in the lateral direction (Y direction).

Further, as shown in FIG. 6, the fixing member 6 has a bolt 65 extending downward from the lower surface of the pillar portion 61, and the bolt 65 is inserted into the rear plate 2 from the upper surface of the rear plate 2. Thereby, the fixing member 6 and the rear plate 2 are fixed. The bolt 62 is separated from the bolt 65. In FIG. 6, two spacers 64 are inserted between the bottom of the recessed portion 7c and the pillar portion 61. The spacer 64 is arbitrarily set Just fine. The configuration of the fixing member 6 will be further described below.

The bottom of the recess 7c is parallel to the flat central portion of the foot support plate 7. Among the recessed portions 7c, the upper end of the side portion on the side after the bottom portion is connected to the flat portion of the foot support plate 7 is connected to the back surface of the flat portion of the foot support plate 7. Among the recesses 7c, the side portion on the front side on the front side of the bottom portion is curved upward from the bottom portion (a direction approaching the center portion of the foot support plate 7). Further, a part of the side portion on the front side is separated in the lateral direction, thereby providing a notch 7b which is a shape in which the front portion of the bottom portion of the concave portion 7c is open. In the notch 7b, the bolt 62 in a state in which the nut 63 is screwed can be inserted as shown in Figs. 5 and 6 .

In addition, the curved portion provided on the side of the side of the concave portion 7c is a portion that suppresses the function of shifting the position of the fixing member 6 that has been inserted into the notch 7b, and functions to improve the structural strength of the concave portion 7c. section.

The suppression of the positional shift is specifically described, and the side portion on the front side of the concave portion 7c is configured as the positional deviation suppressing portion 7d. The upper end of the positional deviation suppressing portion 7d is separated from the rear surface of the central portion of the foot support plate 7 to form an opening portion, and a part of the positional deviation suppressing portion 7d is separated in the lateral direction and is displaced from the bottom of the concave portion 7c to the positional deviation. The portion 7d is formed with a notch 7b. Thereby, the bolt 62 in a state in which the nut 63 is screwed can be inserted into the notch 7b of the recess 7c from the opening. The nut 63 fastened in the inserted state interferes with the inner side surface of the positional deviation suppressing portion 7d. Therefore, even when the snowmobile 10 is used for sliding on the snow, the positional deviation suppressing portion 7d suppresses the nut. The positional displacement of 63 is such that the positional deviation of the fixing member 6 is suppressed.

Further, the curved portion of the positional deviation suppressing portion 7d is realized to maintain the flatness of the bottom portion of the concave portion 7c, particularly the periphery of the notch 7b. Specifically, the bottom of the recess 7c is particularly the periphery of the notch 7b, since the bolt 62 is inserted or the nut 63 is screwed in. The load is applied, so it is assumed that in the case where the bent portion is not provided, the load may cause the periphery of the notch 7b to be distorted, bent, etc., making it difficult to perform smooth insertion without causing pressure on the user, and may also cause the foot support plate 7 Poor fixing to the rear plate 2. However, by providing the curved portion, it is difficult to bend and bend the periphery of the notch 7b. Therefore, the structural strength around the notch 7b can be improved by providing the curved portion.

(Loading and unloading of the rear plate 2 and the foot support plate 7)

The steps of attaching and detaching the rear plate 2 and the foot support plate 7 will be described with reference to Figs. 5 and 6 .

As shown in FIG. 5(a), the foot support plate 7 is relatively moved (sliding) forward with respect to the rear plate 2. Further, as shown in FIG. 5(b), among the fixing members 6 fixed to the rear plate 2, among the bolts 62 to which the nut 63 has been screwed, the portion between the nut 63 and the pillar portion 61 is provided. From the open portion of the front end of the notch 7b, it is inserted into the notch 7b. In this manner, since the front end of the rear side of the notch 7b of the rear plate 2 is opened, even in the state in which the nut 63 is screwed to the bolt 62 in the fixing member 6, the bolt 62 can be inserted. Notch 7b.

Next, as shown in FIG. 5(c), the nut 63 screwed to the bolt 62 is fastened toward the pillar portion 61 in a state in which the bolt 62 is inserted into the notch 7b.

Here, as shown in FIG. 6, the foot support plate 7 is provided with the opening part 7a above the recessed part 7c so that it may overlap with the inside of the recessed part 7c in planar view. The tool 9 for tightening or loosening the nut 63 by a wrench or the like is inserted into the opening 7a from the upper side of the opening 7a, and is inserted into the inside of the recess 7c. Then, the front end of the tool 9 is fitted to the nut 63, and the nut 63 is fastened toward the pillar portion 61.

As a result, as shown in FIG. 5(c) and FIG. 6, the concave portion of the periphery of the notch 7b is obtained. The nut 63 is held by the nut 63 and the post portion 61, whereby the leg support plate 7 is fixed to the rear plate 2 through the fixing member 6. In this manner, the foot support plate 7 can be simply attached to the rear plate 2.

Further, the foot supporting plate 7 is provided with an opening portion 7a for performing the work of fastening or loosening the nut 63, so that the work is easy.

Further, a positional deviation suppressing portion 7d that is bent upward from the bottom of the concave portion 7c is provided around the notch 7b. Further, the width (length in the Y direction) of the notch 7b provided in the positional deviation suppressing portion 7d is smaller than the outer diameter of the nut 63. Thereby, the nut 63 interferes with the inner side surface of the positional deviation suppressing portion 7d in a state where the nut 63 is tightened, and the position of the nut 63 in the recessed portion 7c can be prevented from being displaced while sliding on the snow.

By providing the positional deviation suppressing portion 7d, it is possible to provide the snowmobile gliding 10 which is easy to attach and detach and which is highly reliable in the state in which the foot supporting plate 7 and the rear plate 2 are fixed.

Further, the tool 9 can also be used for fastening or loosening the nut 63 when the front plate 1 and the fork plate 5 are attached and detached.

When the rear plate 2 and the foot support plate 7 are taken out, the order of the steps described in FIGS. 5(a) to 5(c) and FIG. 6 may be reversed.

That is, in (c) of FIG. 5 and FIG. 6, the tool 9 inserted into the recessed portion 7c from the opening portion 7a is fitted into the nut 63, and the nut 63 is loosened toward the upper end of the bolt 62 so as not to be released. The degree of detachment from the bolt 62. Thereby, as shown in FIG. 5(b), the nut 63 is separated from the foot support plate 7. Then, the foot support plate 7 is relatively moved (sliding) rearward with respect to the rear plate 2. As a result, as shown in FIG. 5(a), the portion between the nut 63 and the pillar portion 61 in the bolt 62 in a state in which the nut 63 is screwed is separated from the notch 7b. Thereby, the portion between the nut 63 and the pillar portion 61 in the bolt 62 in which the nut 63 is screwed is released from the notch 7b. So able to The foot support plate 7 is simply taken out from the rear plate 2.
