The specific embodiment

Now, will describe the embodiment of motor bike of the present invention with reference to the accompanying drawings in detail hereinafter.Fig. 1 is the left side view of motor scooter, Fig. 2 is the planar view at the rear portion of motor scooter, seat and bonnet have been taken off from this rear portion, Fig. 3 is the right side view at the rear portion of motor scooter, seat and bonnet have been taken off from this rear portion, Fig. 4 is the left side view of the structure of rear shock absorber, Fig. 5 is the planar view of the structure of rear mudguard, Fig. 6 is the right side view of the supporting structure of rear shock absorber, Fig. 7 is the section-drawing along the line VII-VII of Fig. 6, Fig. 8 is the planar view in helmet cabin, and Fig. 9 is the back view in helmet cabin.

Reference marker 1 among the figure is illustrated in the motor scooter that is provided with stretcher 7 between handle 3 and the seat 5.Motor scooter 1 has the seat 5 that is formed by jockey's seat portion section 5a and tandem seat portion section 5b, makes to take two people.Motor scooter 1 has front fork 6, and this front fork can turn to by handle about 3, and front-wheel 8 is supported by front fork 6.

Unit oscillating-type driving engine 10 is installed on the motor scooter 1, is used for swing up and down.Driving engine 10a that unit oscillating-type driving engine 10 forms as one and transmission gearbox 10b, this transmission gearbox comprise the V band (not shown) that is used for power is passed to from driving engine 10a trailing wheel 20.Transmission gearbox 10b extends back from the left side of the crankcase of driving engine 10a, and trailing wheel 20 is supported in the inboard at the rear portion of transmission gearbox 10b.The rear end of transmission gearbox 10b is supported by the after-frame 41 that constitutes vehicle body 40 by rear shock absorber 30.

Vehicle body 40 trailing wheels 20 and unit oscillating-type driving engine 10 relative sides are provided with postbrachium 11, and trailing wheel 20 is bearing in the rear portion of postbrachium 11.Postbrachium 11 is supported by the after-frame 41 that constitutes vehicle body 40 by rear shock absorber 31, and noise silencer 36 is by postbrachium 11 supportings.Noise silencer 36 extends back from the front portion of driving engine 10a, and is positioned at the right side of trailing wheel 20.

Rear shock absorber 31 on postbrachium one side at one end 31a supports by the attachment section 11a of support unit 32 by postbrachium 11, and is supported by the horizontal adapter 44 that is connected on a pair of after-frame 41 by support unit 33 at other end 31b.As shown in Fig. 6 and 7, support unit 33 includes bolt 33a and nut 33b, and bolt 33a is fastened on the support 49 with nut 33b, and this support is fixed in the horizontal adapter 44.

The other end 31b of rear shock absorber 31 is supported by bolt 33a by sleeve pipe 45.So that when being released, rear shock absorber 31 pivots around the support unit 33 of other end 31b when mobile support parts 32, makes it to move to the place ahead of the front edge of trailing wheel 20, as illustrating by long and two-short dash line among Fig. 3.

In addition, vehicle body 40 is provided with rear mudguard 70, and this rear mudguard is arranged on the top of trailing wheel 20, so that cover its top.Rear shock absorber 30 on driving engine one side passes the opening 71 that is formed in the rear mudguard 70, and the rear shock absorber 31 on postbrachium one side passes the opening 72 that is formed in the rear mudguard 70.

Opening 71 is opened to the degree that the rear shock absorber 30 on driving engine one side can pass, and as shown in Fig. 2 and 5, opening 72 longitudinal extensions, and be opened into like this, be that rear shock absorber 31 on postbrachium one side can pass, and rear shock absorber 31 can move, and makes that the rear shock absorber 31 on postbrachium one side can move to the place ahead of trailing wheel 20 with a kind of so simple structure.

In addition, vehicle body 40 has the helmet cabin 60 below the jockey's seat portion section 5a that is arranged between a pair of after-frame 41.Helmet cabin 60 is arranged in the top of trailing wheel 20 and the top of the place ahead and driving engine 10a in the mode of compactness.Helmet cabin 60 covers with car bonnet 42 in its side, covers with seat 5 at its top.

Seat 5 can pivot forward around preceding bolster 46, makes the top in helmet cabin 60 to open, so that the helmet is put into and taken out.

As shown in Fig. 2,3,8 and 9, helmet cabin 60 is in being formed with recess 60a, so that the rear shock absorber 31 on postbrachium one side can be moved in its part on the right side at its rear portion.Be arranged into depositing of the helmet backward by a part and be not subjected to the degree of interfering helmet cabin 60, the surface of recess 60a form approach flat.Therefore, the rear shock absorber 31 on postbrachium one side can move to the place ahead of trailing wheel 20 with a kind of so simple structure.

In the present embodiment, when when taking off trailing wheel 20 and safeguard, the noise silencer 36 on the right side takes off from postbrachium 11, then, takes off the support unit 32 of rear shock absorber 31, so that discharge the supporting of an end 31a.At one end under the d/d situation of the supporting of 31a, when promoting forward, rear shock absorber 31 rotates pivotly around the support unit 33 of other end 31b, and moves to the place ahead of the front edge of trailing wheel 20, as among Fig. 3 by shown in the long and two-short dash line like that.

After this, when postbrachium 11 when vehicle body 40 takes off, can take off trailing wheel 20.Therefore, can take off trailing wheel 20 and need not to take off rear shock absorber 31 on postbrachium one side, so help handling labor.
