Abstract

Provided is a routing structure for a braking force-transmitting member in a motorcycle in which a front part of a unit-swing engine supporting a rear wheel is supported on a vehicle body frame via a link mechanism, and the braking force-transmitting member is routed to extend in the fore-and-aft direction so as to transmit a braking force to a rear wheel brake disposed coaxially with the rear wheel, wherein the link mechanism includes a first link linked to the vehicle body frame and a second link linked to the unit-swing engine while having an engine suspension boss portion pivotably linked to the first link, and a guide member retaining the braking force-transmitting member extending in the fore-and-aft direction beneath the unit-swing engine is mounted on the second link. This can suppress swinging of a braking force-transmitting member and enables the mass around the braking force-transmitting member to be concentrated.

First claim

The invention claimed is:

1. A routing structure for a braking force-transmitting member in a motorcycle in which a unit-swing engine extending in a fore-and-aft direction so as to axially support a rear wheel via a rear part thereof has a front part swingably supported on a vehicle body frame via a link mechanism, and the braking force-transmitting member for transmitting a braking force to a rear wheel brake disposed coaxially with the rear wheel so as to brake the rear wheel is routed so as to extend in the fore-and-aft direction, wherein the link mechanism comprises a first link linked to the vehicle body frame and a second link linked to the unit-swing engine while having an engine suspension boss portion pivotably linked to the first link, and a guide member retaining the braking force-transmitting member extending in the fore-and-aft direction beneath the unit-swing engine is mounted on the second link,
a center stand is pivotably supported on the second link, and an elastic spring urging the center stand toward a retracted position side is provided between the center stand and a support shaft provided on the second link so as to support the guide member.

2. The routing structure for the braking force-transmitting member in the motorcycle according to claim 1 , wherein the unit-swing engine comprises an engine main body and a transmission case provided so as to be connected to the engine main body and extending rearward, and a cooling duct for introducing cooling air into an interior of the transmission case is disposed above the guide member and the braking force-transmitting member retained by the guide member when viewed from a side.

3. The routing structure for the braking force-transmitting member in the motorcycle according to claim 2 , wherein the guide member is formed so as to comprise a first insertion portion through which the braking force-transmitting member is inserted and retained and a second insertion portion through which a drain tube is inserted and retained, the drain tube guiding water drained from auxiliary equipment mounted on the motorcycle.

4. The routing structure for the braking force-transmitting member in the motorcycle according to claim 1 , wherein the guide member is formed so as to comprise a first insertion portion through which the braking force-transmitting member is inserted and retained and a second insertion portion through which a drain tube is inserted and retained, the drain tube guiding water drained from auxiliary equipment mounted on the motorcycle.

5. The routing structure for the braking force-transmitting member in the motorcycle according to claim 4 , wherein the first insertion portion is formed so as to open in a vehicle width direction when viewed from the side in a state in which the guide member is mounted on the second link and so that an opening area thereof is a maximum in an oblique direction and a minimum when viewed from a rear.
