Abstract: A trim and tilt device includes: a cylinder; a piston; a rod; and a rod guide. The rod includes a first end to which the piston is fixed, and the piston includes an insertion hole to which the first end of the rod is inserted. Over an entire periphery of the rod guide, a lower end of an outer peripheral surface of the rod guide that is in contact with the inner peripheral surface of the cylinder is located closer to a second end of the rod than a lower end of a first inner peripheral surface of the rod guide where the outer peripheral surface of the rod is slidable. An upper end of an outer peripheral surface of the piston is located closer to the second end of the rod than an upper end of the insertion hole.

Abstract: A valve device includes an operating portion including an operating rod switchable between a first state where the operating rod is at a first position, a second state where the operating rod is displaced from the first position, and a third state where the operating rod is displaced from the first position, a push member that can advance by being pushed by the operating rod, a first valve that can be opened and closed in accordance with the amount of displacement of the operating rod and the push member from the first position, a housing storing the first valve, and a second valve that can open and close a communication passage allowing communication inside and outside the housing by switching operation of the operating rod so as to switch from the first state to the second state.
