Abstract

PURPOSE:To obtain a smooth tilt-up by providing a means to detect a helm angle of a propelling unit so that tilt-up operation by a tilt-up device can be performed only when the helm angle indicates an almost neutral position. CONSTITUTION:When a tilt switch 48 is closed toward a up-relay 46 side, a tilt motor 45 makes tilt-up operation via a relay in order to tilt-up a propelling unit. On the other hand, when the switch 48 is closed toward a down-relay 47 side, the motor 45 tilts down the propelling unit via the relay 47. At that time, since a detector 35 turns ON only when the helm angles of the propelling unit and a steering lever indicate an almost neutral position, tilt-up or tilt-down operation is not allowed when helm angle indication is not almost neutral. With this contrivance such accident as the propelling unit and a crank bracket interfere to damage each other, which occurs during tilt-up operation with the large helm angle, can be prevented.

Description

[Detailed description of the invention] The present invention relates to a bouncing device 1' for an inboard/outboard motor.

Conventionally, there was a clamp bracket that was integrated into the hull, a swivel bracket that was supported by the clamp bracket so that it could tilt around a tilt axis that was approximately horizontal, and a swivel bracket that was supported so that it could rotate around a steering axis that was approximately perpendicular to the swivel bracket. There is a typical inboard/outboard motor that has a propulsion unit that is attached to the boat, and a tilt device that is interposed between the hull side and the swivel bracket and tilts the swivel bracket and the propulsion unit to a tilt-up position.

That is, the above-mentioned inboard/outboard motor can be steered by rotating the propulsion unit with respect to the swivel bracket via the steering shaft, and the propulsion unit and the swivel bracket can be clamped via the tilt shaft. When tilting with respect to the bracket: 1 = iJ function of flipping up to the tilt-up position side.

However, in the above-mentioned inboard/outboard motor, when the propulsion unit is tilted up while being held at a large steering angle position from the neutral position, interference occurs between the upper part of the propulsion unit and the clamp bracket, making it difficult to tilt smoothly. A large mJ unit or 6.1 which makes it difficult to operate the amplifier may cause damage to the clamp bracket. .

The present invention C1 is to prevent interference between the soil 111 of the propulsion unit and the clamp bracket. '−r.
