A coolant collector body is provided to block primarily a coolant, which is introduced into a cylinder, by a coolant collecting case, so that an amount of coolant introduced into the cylinder is minimized. A coolant collector case includes a coolant shielding plate(110) formed with a stopper insertion hole. The coolant collector case is coupled to the rear portion of a cylinder(2) to collect coolant. A coolant insertion member having a ring-shape protrusion is a stopper insertion hole of the coolant collector case. A stopper insertion hole is formed at the center portion of the coolant shielding member. A ring-shape protrusion(121) is formed at the edge of the stopper insertion hole. An attachment ring with a bolt hole is formed at the outer side of the ring-shape protrusion.
