Trim and tilt device and marine vessel propelling machine
A trim and tilt device includes: a cylindrical cylinder; a partition member provided in contact with the cylinder so as to be movable in an axial direction of the cylinder and partitioning a space inside the cylinder; a rod member to which the partition member is attached on one end side of the rod member and which moves relatively in the axial direction of the cylinder together with the partition member thereby adjusting a tilt angle of a marine vessel propelling machine body with respect to a hull; and a rod guide member electrically connected to a sacrificial anode and having a hole so that the rod member passes through the hole, and the rod guide member has a conductive portion disposed at a position, where the hole is formed, so as to electrically connect the rod member and the rod guide member.
1. A trim and tilt device comprising:
a cylindrical cylinder;
a partition member provided in contact with the cylinder so as to be movable in an axial direction of the cylinder and partitioning a space inside the cylinder;
a rod member to which the partition member is attached on one end side of the rod member and which moves relatively in the axial direction of the cylinder together with the partition member thereby adjusting a tilt angle of a marine vessel propelling machine body with respect to a hull; and
a rod guide member electrically connected to a sacrificial anode and having a hole so that the rod member passes through the hole, wherein
the rod guide member includes a conductive portion comprising a bearing that supports the rod member and is disposed at a position, where the hole is formed, so as to electrically connect the rod member and the rod guide member.
2. A marine vessel propelling machine comprising:
a marine vessel propelling machine body having a propeller;
a sacrificial anode; and
a trim and tilt device comprising a cylindrical cylinder; a partition member provided in contact with the cylinder so as to be movable in an axial direction of the cylinder and partitioning a space inside the cylinder; a rod member to which the partition member is attached on one end side of the rod member and which moves relatively in the axial direction of the cylinder together with the partition member thereby adjusting a tilt angle of the marine vessel propelling machine body with respect to a hull; and a rod guide member having a hole so that the rod member passes through the hole, wherein
the rod guide member of the trim and tilt device includes a conductive portion comprising a bearing that supports the rod member and is disposed at a position where the hole is formed so as to electrically connect the rod member, the rod guide member and the sacrificial anode.
3. The trim and tilt device of claim 1 , wherein the hole is formed through a body of the rod guide member and the bearing is disposed internally within the hole and contacts the rod member which passes through an opening formed in the bearing.
4. The marine vessel propelling machine of claim 2 , wherein the hole is formed through a body of the rod guide member and the bearing is disposed internally within the hole and contacts the rod member which passes though an opening formed in the bearing.
5. The trim and tilt device of claim 3 , wherein the body of the rod guide member circumferentially surrounds the bearing.
6. The marine vessel propelling machine of claim 4 , wherein the body of the rod guide member circumferentially surrounds the bearing.
