Frame structure for saddle-type vehicle
First Claim
1. A frame structure for a saddle vehicle, comprising:
- a hollow main frame extending rearwardly from a head pipe; and
an air cleaner including a filter element disposed in the hollow main frame, said air cleaner being divided into a dirty side and a clean side by the filter element, the hollow main frame having a front opening defined in a front portion thereof for introducing intake air,wherein the hollow main frame includes an inner wall surface having a first rib extending peripherally and projecting inwardly into a space in the hollow main frame, and a second rib disposed upstream or downstream of the first rib with respect to an intake air flow and projecting inwardly into the space in the hollow main frame,wherein the filter element has an engaging member extending substantially along the inner wall surface and engageable with the second rib,wherein the first rib peripherally surrounds the filter element to provide a division wall with the second rib engaging the filter element to support the filter element, andwherein, as viewed in a sectional side elevation of the hollow main frame, a lower rib wall section of the first rib and a lower wall surface of the inner wall surface which is slanted downwardly toward a projection proximal portion of the lower rib wall section jointly define therebetween a downwardly recessed space disposed upstream of the lower rib wall section of the first rib with respect to the intake air flow.

Abstract
A hollow main frame extends rearwardly from a head pipe. An air cleaner includes a filter element disposed in the main frame forming a dirty side and a clean side. The main frame includes a front opening for introducing intake air. The main frame includes an inner wall surface having a first rib extending peripherally and projecting inwardly into the space in the main frame. A second rib is disposed upstream or downstream of the first rib with respect to an intake air flow and projects inwardly into the space in the main frame. The filter element has an engaging member extending substantially along the inner wall surface and engageable with the second rib. The first rib peripherally surrounds the filter element to provide a division wall with the second rib engaging the filter element to support the filter element.

12. A frame structure for a saddle vehicle, comprising:
-
a hollow main frame extending rearwardly from a head pipe; a front opening defined in a front portion of the hollow main frame for introducing intake air into a space formed in the hollow main frame; an inner wall surface formed within the hollow main frame, said inner wall surface having a first rib extending peripherally and projecting inwardly into the space in the hollow main frame, and a second rib disposed upstream or downstream of the first rib with respect to an intake air flow and projecting inwardly into the space in the hollow main frame; an air cleaner including a filter element disposed within the space formed in the hollow main frame, said air cleaner being divided into a dirty side and a clean side by the filter element; an engaging member formed on the filter element, said engaging member extending substantially along the inner wall surface and engageable with the second rib; and the first rib peripherally surrounds the filter element to provide a division wall with the second rib engaging the filter element to support the filter element, wherein, as viewed in a sectional side elevation of the hollow main frame, a lower rib wall section of the first rib and a lower wall surface of the inner wall surface which is slanted downwardly toward a projection proximal portion of the lower rib wall section jointly define therebetween a downwardly recessed space disposed upstream of the lower rib wall section of the first rib with respect to the intake air flow. - View Dependent Claims (13, 14, 15, 16, 17)
