Abstract

A motorcycle includes a main frame, a seat frame connected to a rear portion of the main frame and extending backward to support a seat, an auxiliary frame reinforcing the seat frame, and an acceleration sensor. The acceleration sensor is supported at a position under the seat frame and above the auxiliary frame in a side view by a bracket extending from the seat frame or the auxiliary frame. Side surfaces of the acceleration sensor are covered with a vehicle body cover.

First claim

The invention claimed is:

1. A motorcycle ( 10 ) comprising:
a main frame ( 21 ) extending backward from a head pipe ( 11 );
a seat frame ( 23 ) connected to a rear portion of the main frame ( 21 ) and extending backward to support a seat ( 19 );
an auxiliary frame ( 29 ) provided under the main frame ( 21 ) and having a rear end connected to the seat frame ( 23 ) to reinforce the seat frame ( 23 ); and
an acceleration sensor ( 60 ) configured to detect an acceleration, wherein the acceleration sensor ( 60 ) is supported at a position under the seat frame ( 23 ) and above the auxiliary frame ( 29 ) in a side view by a bracket ( 61 , 62 ) extending from the seat frame ( 23 ) or the auxiliary frame ( 29 ), and
side surfaces of the acceleration sensor ( 60 ) are covered with a vehicle body cover ( 50 );
the bracket includes:
an arm portion ( 64 ) extending in a vehicle longitudinal direction;
a cross portion ( 65 ) extending in a vehicle width direction and connected to an end of the arm portion ( 64 ); and
support portions ( 66 ) at two ends of the cross portion ( 65 ) in which tubular elastic members ( 67 ) are fitted;

the acceleration sensor ( 60 ) is fixed to the bracket by bolts ( 73 ) through the tubular elastic members ( 67 ) and nuts ( 76 ) fastened to the bolts ( 73 ).

2. The motorcycle according to claim 1 , wherein the acceleration sensor ( 60 ) is arranged in a tilting state.

3. A motorcycle ( 10 ) comprising:
a main frame ( 21 ) extending backward from a head pipe ( 11 );
a seat frame ( 23 ) connected to a rear portion of the main frame ( 21 ) and extending backward to support a seat ( 19 );
an auxiliary frame ( 29 ) provided under the main frame ( 21 ) and having a rear end connected to the seat frame ( 23 ) to reinforce the seat frame ( 23 );
a swing arm ( 25 ) to which a rear wheel ( 26 ) is rotatably attached,
a rear cushion ( 28 ) configured to be bridged over the swing arm ( 25 ) and the rear portion of the main frame ( 21 ), and
an acceleration sensor ( 60 ) configured to detect an acceleration, wherein the acceleration sensor ( 60 ) is supported at a position under the seat frame ( 23 ) and above the auxiliary frame ( 29 ) in a side view by a bracket ( 61 , 62 ) extending from the seat frame ( 23 ) or the auxiliary frame ( 29 ),
side surfaces of the acceleration sensor ( 60 ) are covered with a vehicle body cover ( 50 ), and
in a plan view of the motorcycle, the bracket and an upper end support portion ( 83 ) of the rear cushion ( 28 ) are positioned on a line of a vehicle width direction.

4. A motorcycle ( 10 ) comprising:
a main frame ( 21 ) extending backward from a head pipe ( 11 );
a seat frame ( 23 ) connected to a rear portion of the main frame ( 21 ) and extending backward to support a seat ( 19 );
an auxiliary frame ( 29 ) provided under the main frame ( 21 ) and having a rear end connected to the seat frame ( 23 ) to reinforce the seat frame ( 23 ); and
an acceleration sensor ( 60 ) configured to detect an acceleration, wherein the acceleration sensor ( 60 ) is supported at a position under the seat frame ( 23 ) and above the auxiliary frame ( 29 ) in a side view by a bracket ( 61 , 62 ) extending from the seat frame ( 23 ) or the auxiliary frame ( 29 ),
side surfaces of the acceleration sensor ( 60 ) are covered with a vehicle body cover ( 50 ), and
the acceleration sensor ( 60 ) is arranged at a position where the acceleration sensor ( 60 ) at least partially overlaps the seat frame ( 23 ) or the auxiliary frame ( 29 ) in a plan view.

5. A motorcycle ( 10 ) comprising:
a main frame ( 21 ) extending backward from a head pipe ( 11 );
a seat frame ( 23 ) connected to a rear portion of the main frame ( 21 ) and extending backward to support a seat ( 19 );
an auxiliary frame ( 29 ) provided under the main frame ( 21 ) and having a rear end connected to the seat frame ( 23 ) to reinforce the seat frame ( 23 ); and
an acceleration sensor ( 60 ) configured to detect an acceleration, wherein the acceleration sensor ( 60 ) is supported at a position under the seat frame ( 23 ) and above the auxiliary frame ( 29 ) in a side view by a bracket ( 61 , 62 ) extending from the seat frame ( 23 ) or the auxiliary frame ( 29 ),
side surfaces of the acceleration sensor ( 60 ) are covered with a vehicle body cover ( 50 ), and
the acceleration sensor ( 60 ) is stored in a case ( 71 ) made of a resin, and is provided with a connecting port ( 60 A) of a coupler ( 60 C) on a lower surface side.
