Abstract
A recording tape cartridge includes a reel, a case where the reel is accommodated, an engagement gear that is provided in the reel, and a brake gear which is provided in the case side brake member and in which a mesh state with the engagement gear or a mesh release state with the engagement gear is switched by relative displacement of an axis line direction of the brake member with respect to the reel. In a piece taper tooth of the engagement gear, a mesh surface that is oriented in a winding rotation direction is approximately parallel to a reel axis line direction and an opposite mesh surface is inclined with respect to the reel axis line. A piece taper tooth of the brake gear is a taper tooth that is opposite to the piece taper tooth of the engagement gear.
