Zusammenfassung:	A tilt-trim device (17) for a marine propulsion unit comprises a cylinder means 18 with a rod guide (29) is fixed to the end portion of an outer cylinder (22) a piston (23)fixed to one end portion of a piston rod (24)is freely slidably disposed within an inner cylinder (21) and a hydraulic fluid is filled within the cylinder; and the piston rod passes through the rod guide; a tank device (20) in which the hydraulic fluid can be stored; and a pump device (19) intended to supply into and discharge from the cylinder device the hydraulic fluid within the tank device, thereby causing the expansion and contraction operation of this cylinder device. In this tilt-trim device, each of the inner and outer cylinders is made of pipe material, and the end portion of the outer cylinder is bent inwardly, whereby the rod guide is fixed to the outer cylinder by bent portion(30).
