Claim 0:
1. A trim and tilt device comprising:
a bottomed cylindrical cylinder that stores a fluid;
a piston that is slidable on an inner peripheral surface of the cylinder in an axial direction of the cylinder;
a rod that is a rod-shaped member, the rod including a first end to which the piston is fixed and a second end located at an opposite side to the first end in the axial direction and located outside the cylinder; and
a rod guide that is fixed to the cylinder and slidably supports an outer peripheral surface of the rod in the axial direction,
wherein over an entire periphery of the rod guide, a lower end of a first outer peripheral surface of the rod guide that is in contact with the inner peripheral surface of the cylinder is located closer to the second end than a lower end of a first inner peripheral surface of the rod guide where the outer peripheral surface of the rod is slidable,
wherein the piston includes a second outer peripheral surface that is slidable on the inner peripheral surface of the cylinder and an insertion hole to which the first end of the rod is inserted, and
wherein an upper end of the second outer peripheral surface is located closer to the second end than an upper end of the insertion hole.
