The object of the present invention is to provide an oil garter which is provided in a transmission and which forms an oil passage through which lubricating oil flows and which has an oil drop hole formed at the bottom of the oil passage. A step portion is formed in the bottom portion along the longitudinal direction through the oil drop hole,
That is, the low bottom portion and the high bottom portion are formed in a stepped shape via the step portion.

Since the oil flows through the narrow low-bottom portion, the oil flow is not disturbed, and the oil can be satisfactorily supplied from the oil drop hole to the shift hawk or the like.

よりシフトホークが潤滑されるように構成されている。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an essential part of the oil garter. The oil garter 1 forms a trough-like oil passage R having an open upper side, and side walls 2, which are erected on both sides of the oil passage R. 2 is formed, and a distribution portion 5 is formed at a right angle at the downstream end of the oil passage R. In this example, the oil passage R is formed.
The step portion 4 is formed in a rising shape along the longitudinal direction at the center of the bottom of the
Is formed, and due to the step portion 4, in the width direction of the oil passage R,
A high bottom Ra with a high height and a low bottom Rb with a low height are formed in a step shape, and two oil spills penetrate downward in the distribution section 5 side of the step section 4. When the holes 3 and 3 are opened and the oil garter 1 is arranged in the transmission, the shift fork is lubricated by the oil falling from the oil drop hole 3.

ができるものである。Since the oil drop holes 3 and 3 are formed in the step portion 4, they communicate with the low bottom portion Rb and also with the high bottom portion Ra. When the flow rate of the oil flowing through the oil passage R is large, the oil flows through the entire oil passage R, that is, the oil flows through the low bottom portion Rb and the high bottom portion Ra, so that the flow has a width shown by B in the drawing, and the distributor 5 Oil supply holes 3, 3
It is possible to lubricate the shift hawk by dropping it from the bottom to the bottom.

In such a case, the oil flows even when the vehicle leans or a front and rear G occurs. Flows in the low bottom portion Rb within the narrow width of A, the oil does not concentrate on the side wall 2 side as in the conventional case, and the oil flows along the step portion 4 in the low bottom portion Rb.
The oil flows through the oil drop hole 3 even when the vehicle is tilting and the oil is supplied to the shift hawk. It does not decrease, and the oil can be supplied to the shift hawk side with almost no change even when the vehicle leans.

A step portion is formed at the bottom of the oil passage along the longitudinal direction through the oil drop hole, and the low bottom portion and the high bottom portion are formed in a step shape through the step portion, so that the flow rate of the oil flowing particularly through the oil passage is increased. When the vehicle is leaning, the vehicle will lean, and when G occurs on the vehicle, the oil will flow through the narrow low bottom, so that the oil can be dropped well from the oil drop hole and the shift hawk etc. can be lubricated well. Therefore, the oil can be satisfactorily supplied from the oil drop hole without being affected by the inclination of the vehicle.
