PROBLEM TO BE SOLVED: To provide a lubrication oil feeding device to stably feeding lubrication oil for a very long period by supplying lubrication oil from an external part to a lubrication oil occlusion body in a casing and to provide a linear motion device. SOLUTION: This feeding device 4 is mounted on a slide member engaged with a track shaft 1 through a rolling body and lubrication oil is applied on the track shaft along with relative movement between the slide member and the track shaft. In this case, the lubrication oil feeding device comprises a coating body 41 brought into contact with the track shaft 1 and coating the track shaft 1 with lubrication oil; an occlusion body 42 to absorb lubrication oil and hold this oil and meanwhile feed lubrication oil to the coating body 41; a flow rate control means 43 to control an amount of lubrication oil fed from the occlusion body 42 to the coating body 41; a casing 40 having a lubrication oil containing chamber 44 to contain the coating body 41, the occlusion body 42, and the flow rate control means 43 and fixed at the slide member. Further, a lubrication oil supply hole 6 to supply lubrication oil to the occlusion body 42 is formed in the casing 40.
