In the seat hinge 50 of present embodiment, the second hinge member 52, rotates between the first state shown in Figure 4 and the second state shown in Figure 5 centered by link pin 67 with respect to the first hinge member 51.
Under the first state, can be seated at seat 31.Under the second state, the opening of baggage container 30 is opened, and can the luggage such as the helmet be put into respect to baggage container 30 and take out.
Under the first state shown in Figure 4, link pin 67 due to the elastic force pressure of leaf spring 54 by pushing and pressing in the upper end of pin support holes 56a, 57a, thereby be formed with the gap of regulation between the bottom of link pin 67 and pin support holes 56a, 57a.And, under this state, the length L 3 between the rising wood of end (protrusion) 60a, the 60b of camming surface 64b, 65b and rod-like members 60 is longer than the length L 4 in the lower edge of the axial region of link pin 67 and the gap between pin support holes 56a, 57a.
Under the first state shown in Figure 4, if the occupant is seated at seat 31, apply the load of downward direction, so as shown in Figure 6, link pin 67 is resisted the elastic force pressure of leaf springs 54 and is descended, and moves downwards until pushed against on the bottom of pin support holes 56a, 57a.Like this, upper wall portions 66 pushings that together descended with link pin 67 of test section 70.Thus, seat switch 53 detects the situation that the occupant takes a seat.
In addition, the length L 3 between the rising wood of end (protrusion) 60a, the 60b of camming surface 64b, 65b and rod-like members 60 can also be set as shorter than the length L 4 in the lower edge of the axial region of link pin 67 and the gap between pin support holes 56a, 57a.In this situation, link pin 67 moves downwards until camming surface 64b, 65b are pushed against on the end of rod-like members 60 (protrusion) 60a, 60b.
Then, under state shown in Figure 6, if the occupant gets on or off the bus from seat 31, as shown in Figure 4, link pin 67 rises by the elastic force pressure of leaf spring 54, returns to by the state of pushing and pressing in the upper end of pin support holes 56a, 57a.So the upper wall portions 66 of pushing test section 70 together rises with link pin 67.Thus, seat switch 53 detects the situation that the occupant does not take a seat.
On the other hand, under the second state shown in Figure 5, similarly, link pin 67 is pushed against the upper end at pin support holes 56a, 57a under the effect of the elastic force pressure of leaf spring 54.Herein, constitute, under the first state from the center P of pin support holes 64a, 65a the length L 1 of camming surface 64b, the 65b below be positioned at than from the center P of pin support holes 64a, 65a to the length L 2 of camming surface 64b, 65b below being positioned under the second state short (with reference to Fig. 4 and Fig. 5).Therefore, under the second state, length L 5 between the rising wood of the end of camming surface 64b, 65b and rod-like members 60 (protrusion) 60a, 60b is than the length L 3 short (with reference to Fig. 4 and Fig. 5) between the rising wood of end (protrusion) 60a, the 60b of the length L 4 in the lower edge of the axial region of link pin 67 and the gap between pin support holes 56a, 57a and camming surface 64b, 65b under the first state and rod-like members 60.Thus, if applying the load of downward direction under the second state on seat 31, under link pin 67 had descended the state of length L 5, end (protrusion) 60a of camming surface 64b, 65b and rod-like members 60,60b butt stoped link pin 67 further movement downwards.
That is to say, under the second state shown in Figure 5, camming surface 64b, 65b be close to end (protrusion) 60a, the 60b of rod-like members 60, is arranged on seat 31 on the second hinge member 52 and compares with the first state in the movement of above-below direction and be restricted.
Two-wheeled motor vehicle 1 according to having seat hinge structure of the present invention described above can obtain following effect.
