The invention claimed is: 1. A hand power tool, having a housing (6), an electric motor accommodated in the housing, a battery pack (4), releasably locked to the housing with a detent-locking device (26) and having detent elements (30), for supplying the electric motor with electric current, and at
The invention claimed is: 1. A hand power tool, having a housing (6), an electric motor accommodated in the housing, a battery pack (4), releasably locked to the housing with a detent-locking device (26) and having detent elements (30), for supplying the electric motor with electric current, and at least one spring-like damping element (38), mounted between the battery pack (4) and the housing (6) of the hand power tool (2), for damping vibration and for eliminating a locking-dictated play between the battery pack (4) and the housing (6), wherein said at least one spring-like damping element (38) is provided in said housing and is integrally joined to said housing (6) and wherein the at least one spring-like damping element (38) is configured to rest against a surface (42) of the detent-locking device (24) and is deformable in a direction (R) of deflection of the detent elements (30) upon locking together of the battery pack (4) and the housing (6). 2. The hand power tool according to claim 1, characterized in that at least one spring-like damping element (38) enters into touch engagement with the battery pack (4) upon locking together of the battery pack (4) and the housing (6). 3. The hand power tool according to claim 2, characterized in that the spring-like damping element (38) enters into touch engagement with a surface (42) oriented substantially perpendicular to a primary vibration direction (P) of the hand power tool. 4. The hand power tool according to claim 3, characterized in that the surface (42) is inclined or rounded. 5. The hand power tool according to claim 1, characterized in that the spring-like damping element (38) is deformable in a direction that corresponds to a primary vibration direction (P) of the hand power tool. 6. The hand power tool according to claim 1, characterized in that the spring-like damping element (38) is deformable in a direction that is perpendicular to a direction (R) of a deflection of detent elements (32) upon locking together of the battery pack (4) and the housing (6). 7. The hand power tool according to claim 1, characterized in that the spring-like damping element (38) comprises a rubber-elastic material. 8. The hand power tool according to claim 1, characterized in that the spring-like damping element (38) comprises a material that is joined integrally to the housing (6) by injection molding. 9. The hand power tool according to claim 1, characterized in that the spring-like damping element (38) comprises a thermoplastic elastomer. 10. The hand power tool according to claim 1, characterized in that a plurality of spring-like damping elements (38) are spaced apart from one another and integrally joined to the housing. 11. The hand power tool according to claim 1, characterized in that the spring-like damping element comprises one spring element and one damping element.
