To provide a motor case which has a large amount of a propellant and a small number of components and inhibits occurrence of burst.SOLUTION: A rocket motor 1 has: a propellant 5 for propelling a rocket; a motor case 1a which encloses the propellant 5 therein and includes a nozzle 3b at one end part; and an insulator including an inner peripheral surface facing the propellant 5 and an outer peripheral surface facing the motor case 1a. The inner peripheral surface of the insulator has: an insulator adhesion area 4g adhered to an entire outer periphery of the propellant 5. The outer peripheral surface of the insulator has: a case adhesion area 6b adhered to an inner peripheral surface of the motor case 1a; and a case non-adhesion area 6a which is not adhered to the inner peripheral surface of the motor case.SELECTED DRAWING: Figure 3

    【課題】推進薬の量が多く、かつ部品点数が少なく、しかもバーストが生じることが抑制されたモータケースを提供する。【解決手段】ロケットモータ1であって、ロケットを推進させるための推進薬5と、推進薬5を内包しかつ一端部にノズル3bを備えるモータケース1aと、推進薬5に対向する内周面とモータケース1aに対向する外周面を具備するインシュレータを有し、インシュレータの内周面は、推進薬5の外周全体に接着されるインシュレータ接着領域4gを有し、インシュレータの外周面は、モータケース1aの内周面と接着されるケース接着領域6bと、モータケース内周面に接着されないケース未接着領域6aを有する。【選択図】図3
