Abstract

PURPOSE:To achieve the stable fixing of a sleeve by clamping the outer peripheral groove of the sleeve from both sides, and fixing the sleeve to a valve hole of a valve body by engaging means engaged in the inner peripheral groove of the valve hole. CONSTITUTION:An engaging means 8 made of elastic material rich in rigidity comprises circular-arc both side clamping portions 81 for clamping the base of an outer peripheral groove 3 of a sleeve 4 from both sides, a connecting portion 83 engaged with the wall surface of a slit 5 and adapted to connect both clamping portions 81, and forward end engaging portions 85 extended from the clamping portions 81, bent and expanded outward to be put in an inner peripheral groove 7 of a valve hole 2. When external force is applied to the sleeve 4, the engaging portions 85 and the connecting portion 83 are engaged with the wall of the inner peripheral groove 7 and the wall of the slit 5.

いた。[Prior Art] Automatic transmissions use a hydraulic control device that incorporates a spool, a spring, a sleeve, etc. into a valve body in which valve holes, oil passages, etc. are provided in a predetermined pattern. The sleeve serves as a plug for the valve hole, and is usually fitted into the front end of the valve hole to facilitate machining of the valve hole and assembly of the spool, such as when providing a spool with a difference in the outer diameter of the land. Conventionally, the sleeve is fixed in the valve hole 2 provided in the valve body 1, as shown in FIG.
A sleeve 4 having a circumferential outer groove 3 formed therein is fitted into the sleeve 4, and a slit 5 is formed in the wall of the pulp body 1 so as to correspond to the outer circumferential groove 3 and perpendicular to the central axis of the valve hole 2.
, both end locking portions 61.61 made of a bar-shaped or band-shaped metal bending body and fitted into the outer circumferential groove 3; and a connecting portion that is locked to the wall of the slit 5 and connects the both locking portions 61.61. This was done by inserting a locking tool 6 having a diameter of 62.

Since there is a gap (backlash) between the locking tool 6 and the locking tool 6 due to manufacturing tolerances and play for smooth installation of the locking tool 6, the fifth
As shown in the figure, when an external force in the direction of the arrow is applied to the sleeve 4 due to hydraulic pressure, the locking tool 6 is pried and the sleeve 4 is
is displaced outward, resulting in unstable fixation of the sleeve 4 and easy deformation of the locking tool, making it difficult to obtain an appropriate fixing position for the sleeve 4.
