FIG. 7 is a cross-sectional view illustrating a mounting structure and an operation of the operation unit 58.
The cross-sectional view of the locked state of the operation unit 58 illustrated in A is a cross-sectional view taken along line VII-VII of FIG. 2, and the operation unit 58 is not movable with respect to the vertically extending portion 53b. In addition, in the unlocked state of the operation unit 58 illustrated in B, the operation unit 58 is movable with respect to the vertically extending portion 53b. 
The vertically extending portion 53b of the fixing member 53, at the upper end portion and the lower end portion of the guide hole 53g, has a large-diameter hole portion 53n having an inner diameter larger than the width in the front-rear direction of the vertically intermediate portion 53m of the guide hole 53g. The inner peripheral surface of the large-diameter hole portion 53n is formed in a tapered shape in which the inner diameter increases toward the outside in the vehicle width direction. The shaft 67 penetrates the large-diameter hole portion 53n. 
The lower upright portion 56d of the screen attachment member 56 includes a cylindrical portion 56e protruding outward in the vehicle width direction at the lower end portion and surrounding the periphery of the shaft 67, and a lower cover portion 56f covering the cylindrical portion 56e from below.
The operation unit 58 includes an inner cylinder 58a, a bottom portion 58b, a male tapered portion 58c, a small-diameter cylinder portion 58d, and a grip portion 58e. 
The inner cylinder 58a is movably inserted into the cylindrical portion 56e of the screen attachment member 56. The male tapered portion 58c is formed in a tapered shape in which the outer peripheral surface becomes smaller toward the inside in the vehicle width direction, extends inward in the vehicle width direction from the bottom portion 58b of the inner cylinder 58a, and is fitted into the large-diameter hole portion 53n of the guide hole 53g of the fixing member 53.
The small-diameter cylinder portion 58d extends outward in the vehicle width direction from the bottom portion 58b of the inner cylinder 58a. The grip portion 58e is an outer cylinder that once extends radially outward from the outer end portion in the vehicle width direction of the inner cylinder 58a and covers the periphery of the inner cylinder 58a, and includes an outer grip portion 58f, an inner grip portion 58g, and a flange portion 58h in order from the outer side in the vehicle width direction.
The outer grip portion 58f and the inner grip portion 58g are portions to be gripped by hand at the time of operation, and the inner grip portion 58g has an outer diameter smaller than that of the outer grip portion 58f so that it is easy to place a hand on the outer grip portion 58f when sliding the operation unit 58 in the axial direction of the shaft 67.
The flange portion 58h is a portion that prevents fingers of the hand from entering between the operation unit 58 (specifically, the flange portion 58h) and the lower upright portion 56d of the screen attachment member 56 when the outer grip portion 58f and the inner grip portion 58g are gripped by hand.
An inner cylindrical portion 58j is integrally provided on the inner side of the flange portion 58h in the vehicle width direction. The inner cylindrical portion 58j constitutes a part of the operation unit 58.
The inner cylindrical portion 58j forms a labyrinth structure with the lower cover portion 56f of the screen attachment member 56 and is a portion that makes it difficult for a scattering object from the road surface side to enter between the cylindrical portion 56e of the screen attachment member 56 and the grip portion 58e. 
In the shaft 67, a pair of left and right retaining members 101 is fitted inside the fixing member 53 in order to prevent it from becoming detached from the fixing member 53.
In addition, collar members 103 are fitted to both ends of the shaft 67. The collar member 103 integrally includes a small-diameter inner cylinder portion 103a fitted to the shaft 67 and a large-diameter outer cylinder portion 103b extending radially outward and outward in the vehicle width direction from a lengthwise intermediate portion of the inner cylinder portion 103a. 
The inner cylinder portion 103a includes a tapered diameter-reduced portion 103c at an outer end portion in the vehicle width direction. The diameter-reduced portion 103c is fitted into an annular groove 67a formed at both ends of the shaft 67.
A compression coil spring 105 is disposed between the bottom portion 103d of the outer cylinder portion 103b and the bottom portion 58b of the inner cylinder 58a of the operation unit 58, and both end portions of the compression coil spring 105 are pressed against the bottom portion 103d and the bottom portion 58b, respectively.
As a result, the operation unit 58 is biased inward in the vehicle width direction with respect to the collar member 103, the male tapered portion 58c of the operation unit 58 is pressed against the inner peripheral surface of the large-diameter hole portion 53n of the guide hole 53g of the fixing member 53, and the operation unit 58 is maintained in the locked state.
In the locked state of the operation unit 58 illustrated in A, the windscreen 42 (see FIG. 6) is held at a low position. In order to change the locked state of the operation unit 58 illustrated in A to the unlocked state of the operation unit 58 illustrated in B, first, as indicated by arrow C, the grip portions 58e of the left and right operation units 58 are respectively gripped and slid outward in the vehicle width direction along the shaft 67. As a result, the male tapered portion 58c of the operation unit 58 is detached from the large-diameter hole portion 53n of the guide hole 53g of the fixing member 53.
Then, in this state, as indicated by arrow D, the left and right operation units 58 are moved to the side of the large-diameter hole portion 53n at the upper end portion of the guide hole 53g along the guide hole 53g. Then, the left and right operation units 58 are slid inward in the vehicle width direction, and the male tapered portion 58c is inserted into the large-diameter hole portion 53n on the upper side. At this time, since the operation unit 58 is biased inward in the vehicle width direction by the compression coil spring 105, the male tapered portion 58c is pressed against the large-diameter hole portion 53n of the guide hole 53g, and the operation unit 58 is in the locked state. As a result, the windscreen 42 is held at a high position.
FIG. 8 is a perspective view illustrating a low position abutment portion 107 between the fixing member 53 and the screen attachment member 56.
On the front surface 53p of the upper portion of each of the left and right vertically extending portions 53b of the fixing member 53, a vertically long fixing portion upper protruding portion 53q protruding forward is integrally formed.
The fixing portion upper protruding portion 53q includes, on a front surface 55b thereof, a flat surface 55c formed at a lower portion, and a curved surface 55d extending so as to curve backward from an upper end of the flat surface 55c. 
In addition, an inner portion protruding portion 56h which protrudes inward in the vehicle width direction and is brought into contact with the fixing portion upper protruding portion 53q of the fixing member 53 is formed on a rear portion of an inner side surface 56g of the upper attachment seat 56b of the screen attachment member 56.
The fixing portion upper protruding portion 53q and the inner portion protruding portion 56h described above constitute a low position abutment portion 107 that comes into an abutting state when the windscreen 42 (see FIG. 6) is at a low position.
When the screen attachment member 56 together with the windscreen 42 (see FIG. 6) descends from above to the lowermost end of elevation, the inner portion protruding portion 56h is in contact with the fixing portion upper protruding portion 53q. In this state, the screen attachment member 56 is held without rattling with respect to the fixing member 53.
In addition, when the screen attachment member 56 ascends from the lowermost end of elevation, the inner portion protruding portion 56h is separated from the fixing portion upper protruding portion 53q, so that holding of the screen attachment member 56 with respect to the fixing member 53 is released.
Since the front surface 55b of the fixing portion upper protruding portion 53q gradually curves backward from the lower end side to the upper end side, the abutment force of the inner portion protruding portion 56h with respect to the fixing portion upper protruding portion 53q gradually increases after the inner portion protruding portion 56h starts being in contact with the fixing portion upper protruding portion 53q from above. With such a structure, it is possible to make the inner portion protruding portion 56h easily and smoothly be in contact with the fixing portion upper protruding portion 53q and also secure the holding force by which the fixing member 53 holds the screen attachment member 56 easily.
FIG. 9 is a side view illustrating a high position abutment portion 108 between the fixing member 53 and the screen attachment member 56.
A front surface 53r of each of the left and right side wall portions 53e of the fixing member 53 includes upper and lower surfaces 53s extending vertically and a curved surface 53t curved forward from the upper end of the upper and lower surfaces 53s, and a front protruding portion 53u protruding forward is formed over the upper and lower surfaces 53s and the curved surface 53t. 
In addition, a rear protruding portion 56m which protrudes rearward and is brought into contact with the front protruding portion 53u of the fixing member 53 is formed at a rear portion of a cylindrical lower cylinder portion 56j (specifically, an outer peripheral surface 56k of the lower cylinder portion 56j) provided at a lower portion of the lower upright portion 56d of the screen attachment member 56.
The front protruding portion 53u of the fixing member 53 described above and the rear protruding portion 56m of the screen attachment member 56 constitute a high position abutment portion 108 that comes into an abutting state when the windscreen 42 (see FIG. 6) is at a high position.
When the screen attachment member 56 together with the windscreen 42 ascends from below to the highest end of elevation, the rear protruding portion 56m is in contact with the front protruding portion 53u. In this state, the screen attachment member 56 is held without rattling with respect to the fixing member 53.
In addition, when the screen attachment member 56 descends from the uppermost end of elevation, the rear protruding portion 56m is separated from the front protruding portion 53u, so that holding of the screen attachment member 56 with respect to the fixing member 53 is released.
The front protruding portion 53u is formed over the upper and lower surfaces 53s and the curved surface 53t. Since the front surface 55e of the front protruding portion 53u curves so as to gradually protrude forward from the lower end side to the upper end side, the abutment force of the rear protruding portion 56m with respect to the front protruding portion 53u gradually increases after the rear protruding portion 56m starts being in contact with the front protruding portion 53u from below. With such a structure, it is possible to make the rear protruding portion 56m easily and smoothly be in contact with the front protruding portion 53u and also secure the holding force by which the fixing member 53 holds the screen attachment member 56 easily.
