Claim:
1. An oil injector for a vehicle comprising: a body being transparent and having a flowing hole formed at a front end thereof, a flexible tube member connected to the body and corresponding to the flowing hole, a storing space formed in an internal portion of the body; and one end of a piston member entered into the storing space, the piston member being movable relative to the body; wherein, the piston member provides a pushing function in the storing space so that a fluid flows into or out from the body via the tube member, and the transparent body is provided for observing a storing amount of the fluid in the body; wherein the front end of the body is integrally protrudingly tapered and formed with a threaded portion around the flowing hole, a valve member is threaded to the threaded portion, a controlling member is disposed around the valve member; wherein the controlling member includes an outer tubular member disposed around the valve member and an inner tubular member sleeved between the outer tubular member and the valve member, and the inner tubular member integrally taperedly projects out of the outer tubular member to form a necked tube portion for the flexible tube member to be sleeved thereon; wherein the inner tubular member is helically movable between a first position and a second position relative to the outer tubular member and the valve member for controlling a flowing amount between the valve member and the tube member; a rib portion and at least one through hole are disposed at a front end of the valve member; when the inner tubular member is located at the first position, the rib portion does not abut against an internal wall of the inner tubular member, so that the flowing hole communicates with the through hole and the tube member; when the inner tubular member is located at the second position, the valve member abuts against the internal wall of the inner tubular member, so that the through hole does not communicate with the tube member.
