Abstract

A saddle type vehicle to improve the workability in fastening a frame and an engine together and thereby to enhance productivity. The saddle type vehicle includes a head pipe, a main frame extending rearwardly from the head pipe, and a seat rail located rearwardly of the main frame for supporting a seat. The main frame is fastened to the engine by fastening members being directed from an outer side toward an inner side in the vehicle widthwise direction. A knock pin is provided between the main frame and the engine, in a position in the vicinity of at least one of the fastening members.

First claim

What is claimed is:

1. A saddle vehicle comprising:
a head pipe;
a main frame extending rearwardly from the head pipe; and
a seat rail located rearwardly of the main frame, the seal rail being adapted to support a seat;
wherein the main frame is fastened to an engine by a fastening member being directed from an outer side toward an inner side in a vehicle widthwise direction; and
a knock pin including first and second knock pins provided between the main frame and the engine, in a position adjacent to the fastening member;
wherein the first knock pin is set along a direction orthogonal to the vehicle widthwise direction and the second knock pin is set along the vehicle widthwise direction and wherein the first knock pin is located between the fastening member and the second knock pin in a longitudinal direction of the vehicle.

2. The saddle vehicle according to claim 1 , wherein the main frame and the seat rail are separate bodies from each other, and the fastening member is provided only on the main frame, and is provided at each of four parts including front left, front right, rear left, and rear right parts of a lower portion of the main frame.

3. The saddle vehicle according to claim 1 , wherein the first knock pin is provided at each of a front-side or a rear-side of the fastening member including the front left, front right, rear left, and rear right parts of the lower portion of the main frame, the first knock pin being located under the fastening member.

4. The saddle vehicle according to claim 1 ,
wherein the second knock pin is provided under the fastening member at a front left, front right, rear left, and rear right parts of the lower portion of the main frame; and
the second knock pin includes a male screw portion and a fitting portion, the male screw portion being for screw coupling with a female screw portion provided in the main frame, the fitting portion being located more to a tip side than the male screw portion and being for fitting to a fitting portion provided in the engine.

5. The saddle vehicle according to claim 1 , wherein the engine has a V-bank configuration in which cylinders are arranged in a V-shape in a side view, in which a rear portion of a front bank and a front portion of a rear bank are fastened by the fastening member, and in which the fastening member, the first knock pin, and the second knock pin are arranged in this order along a direction from a center line of the V-bank configuration toward an outer side in the longitudinal direction of the vehicle.

6. The saddle vehicle according to claim 3 , wherein the engine has a V-bank configuration in which cylinders are arranged in a V-shape in a side view, in which a rear portion of a front bank and a front portion of a rear bank are fastened by the fastening member, and in which the fastening member, the first knock pin, and the second knock pin are arranged in this order along a direction from a center line of the V-bank configuration toward an outer side in the longitudinal direction of the vehicle.

7. The saddle vehicle according to claim 5 ,
wherein a mating surface between the main frame and the engine where the first knock pin is accommodated is provided in each of four places including front left, front right, rear left, and rear right places; and
the mating surface and the center line of the V-bank configuration are orthogonal to each other in the side view.

8. The saddle vehicle according to claim 5 , wherein an intake funnel is provided between the cylinders arranged in the V-shape in the side view, the intake funnel is opening into an air cleaner case formed inside the main frame, and a dirty side of the air cleaner case is provided with a water drain hole through which to release water that tends to accumulate in the dirty side.

9. The saddle vehicle according to claim 7 , wherein an intake funnel is provided between the cylinders arranged in the V-shape in the side view, the intake funnel is opening into an air cleaner case formed inside the main frame, and a dirty side of the air cleaner case is provided with a water drain hole through which to release water that tends to accumulate in the dirty side.

10. A saddle vehicle comprising:
a main frame; and
a seat rail located rearwardly of the main frame;
a fastening member for fastening the main frame to an engine, said fastening member being directed from an outer side toward an inner side in a vehicle widthwise direction; and
a knock pin including first and second knock pins provided between the main frame and the engine, in a position adjacent to the fastening member;
wherein the first knock pin is set along a direction orthogonal to the vehicle widthwise direction and the second knock pin is set along the vehicle widthwise direction and wherein the first knock pin is located between the fastening member and the second knock pin in a longitudinal direction of the vehicle.

11. The saddle vehicle according to claim 10 , wherein the main frame and the seat rail are separate bodies from each other, and the fastening member is provided only on the main frame, and is provided at each of four parts including front left, front right, rear left, and rear right parts of a lower portion of the main frame.
